038776236240FFFB2DEFB18DFA7A5DB2.taxon	description	Recognition. In addition to the characters states of subtribe Metallicina (Shpeley, 1986: 268), adults of the genus Parena can be recognized by: Head and pronotum yellowish brown to piceous, not metallic; elytra color various, unicolor or with pattern, metallic or not; antennomeres 5 – 11 with sensory pits on ventral and dorsal surfaces; elytral interval 9 less than half width of normal intervals; each claw with six to ten long pectinations; male mesotarsi with biseriate adhesive setae ventrally. Endophallus of male genitalia with a well chitinized primary sclerite; without flagellum or with flagellum much shorter than aedeagus (compared to Euproctinus); without a group of spines (compared to Metallica and Pachycallida). Gonocoxite II of female ovipositor subquadrate or dichotomous, with four to seven ensiform setae, without membranous apex. Compared with other Lebiini genera showing similar appearances (e. g., Calleida, Paraphaea, Peliocypas), Parena can be recognized by the combination of following external features: mandibles strongly widened; mentum without median tooth; apex of glossal sclerite with four or more apical setae; terminal palpomeres fusiform; cleaning spur close to inner margin of protibia; tarsomeres 4 bilobed; claws strongly pectinate. Morphology. General features: Members of genus Parena are median-sized truncatipennes ground beetles, body length between 6.3 – 11.7 mm; body form sub-depressed, slightly widened at the apical third of elytra. Color: The head uniformly reddish brown to piceous in most species. Frons with a triangular red patch in some dark species of subgenera Parena and Bothynoptera. Clypeus same color as frons or paler (in some dark species). Mouthparts slightly paler than the head in most species, with terminal palpomeres gradually lightened to apex. Antennomere 1 yellowish or reddish brown, slightly paler than head in most species. Antennomeres 2 – 4 same color as antennomere 1 in most species, but nearly black in some species of the P. testacea species group. Antennomeres 5 – 11, and also the apical half of antennomere 4 darkened in the subgenus Crossoglossa and part of the subgenus Parena, but same color as basal antennomeres in the subgenus Bothynoptera and part of the subgenus Parena. Pronotum with disc same color as the head, usually without a well-defined pattern, but with a pair of black stripes in P. emarginata sp. n.; lateral explanations somewhat lighter than disc. Elytral colors varied: uniformly brown or metallic, with diverse dark or light patterns, or with black or metallic lateral stripes. For some of those patterned species, the style of elytra pattern is stable and has importance in species determination; but in other cases, the elytra patterns present dimorphism (e. g., P. africana) or pleomorphism (e. g., P. fasciata), or are varied individually (e. g., P. nigrolineata) or in different geographical populations (e. g., P. malaisei). The entire venter same color as the pronotum in most species, with the exceptions of P. sciakyi sp. n. and P. heteronycha sp. n., which have the metasternum much darker than other parts. Major parts of the legs are usually in the same color as the pronotum. Femora are unicolor in most species, but those of P. picipes sp. n. are black at the apical half. Tibiae are usually the same color as the apical half of femora, with the only exception that the tibiae of P. cruralis are black in contrast to the pale yellow femora. Tarsomeres are the same color as the femora and tibiae for most species, but slightly lighter in some dark species (e. g., P. obscura), or distinctly darkened in all members of the P. testacea group and some of these African species. Microsculpture: Head and pronotum without microsculpture. Labrum with distinct isodiametric microsculpture. Elytra without microsculpture or with shallow isodiametric microsculpture (no species with transverse microsculpture). The presence of elytral microsculpture has no sexual dimorphism but is sometimes variable within species (e. g., P. tripunctata). Head: Vertex shallowly swollen, with surface smooth or finely punctate. Dorsal surface of the head without accessory setae, but with sparse short setae behind the vertex in some species (e. g., P. dorsigera). Frons with a Vshaped depression in the middle, shallow in some species but always recognizable. Frontal furrows shallow and wide, terminated before midpoint of the eyes. Frontoclypeal suture distinct in most species, but partly fused at the middle in some species. Clypeus subquadrate and bisetose. Eyes very large, hemispheric, and strongly convex. Tempora abruptly narrowed, very short with length approximately one-eighth diameter of eye in most species, but much longer in the P. tesari group (one-third to half diameter of eye). Head behind the tempora constricted, parallel-sided, forming the neck-constriction. The sum of the length of the neck-constriction and tempora (namely the distance between the posterior margins of eyes and pronotal anterior angles) is approximately one-third the diameter of the eye in most species, but more than two-thirds of the diameter of the eye in the P. tesari group. Postgenae with a pair of long suborbital setae close to the gular sutures in all species of subgenera Crossoglossa and Bothynoptera (Fig. 3 E). Suborbital setae are similar length to the supraorbital setae, but are short (less than half length of the supraorbital setae) in P. heteronycha sp. n. In the subgenus Parena, the suborbital setae absent (Fig. 3 F) for most species, but present in species of the P. bicolor and P. stigmatica groups. In a few individuals of the P. dorsigera group, there are two suborbital setae on each side. Antennae: Similar to other arboreal groups of Lebiini, members of Parena have relatively short antennae, barely extended to the base of pronotum in the subgenera Crossoglossa and Parena, extended about one antennomere length beyond the elytral base in the subgenus Bothynoptera. Antennomere 1 thick and arcuate, with a depressed posterior surface (accommodating the convex eyes), with dorsal-posterior margin distinctly ridged and ventral-posterior margin indistinctly ridged. Antennomere 1 with two primary setae near the apex, with the ventral one less than half length of the dorsal one (Figs 1 A, 1 B, 1 C) in most species, but only slightly shorter in the P. scutata group (Fig. 1 D). Antennomere 2 has two primary setae of similar length near the apex. Antennomere 3 has five or six primary setae forming the apical ring. The accessory setae on antennomeres 1 – 3 are absent or represented only by sparse, very short and fine ones in the subgenera Crossoglossa and Parena (Figs 1 A, 1 C, 1 D). Accessory setae are more abundant and longer in the subgenus Bothynoptera, with one or two of them on the antennomere 2 of similar length to the primary ones (Fig. 1 B). The apical half of antennomere 4 and all of the following more distal antennomeres are pubescent. Sensory pits are on both dorsal and ventral surfaces of antennomeres 5 – 11 (Fig. 1 E). Mouthparts: Labrum (Figs 1 F, 1 G) nearly quadrate or very slightly dilated towards the apex, length about two-thirds of width. with six apical setae almost evenly arranged. Apical margin nearly straight in most species (Fig. 1 F) or slightly convex, very weakly emarginate in several species of the P. tripunctata group and distinctly emarginate in P. emarginata sp. n. (Fig. 46 C). Mandibles widened, with arcuate external edges and strongly extended mandibular scrobes, conspicuously widened in subgenera Crossoglossa and Parena, with each roughly semicircular (Figs 2 A, 2 B), and less widened in subgenus Bothynoptera, with each rounded-triangular (Figs 2 C, 2 D, 2 E). Mandibular apices very shortly hooked and suddenly turned inward, but slightly more elongate and less turned inward in P. heteronycha sp. n. (Fig. 26 C). Left mandible with inner edge of the apical hook formed by the shortened terebral ridge and the cutting edge formed by the retinacular ridge. Right mandible with the cutting edge formed by the terebral ridge. Retinacular ridge of right mandible reduced to a retinacular tooth (rr in Figs 2 A, 2 B) in subgenera Crossoglossa and Parena, but present as a shortened ridge in subgenus Bothynoptera. In most species of Bothynoptera (rr in Figs 2 C, 2 E), its length is about one-third of the terebral ridge in ventral view, but more than half of the terebral ridge in P. heteronycha sp. n. (Fig. 26 C) and P. taiwana (rr in Fig. 2 D). Ventral grooves present, more than two-thirds length of the mandibular mesal edges. Maxillae (Fig. 1 H): apex of lacinia strongly hooked, with a smooth inner curved surface. Terminal maxillary palpomeres fusiform in both sexes, glabrous and longer than the penultimate palpomere. Penultimate and antepenultimate palpomeres with several short setae near apex. Mentum varied in shape, without a median tooth, with a pair of setae in subgenera Bothynoptera and Parena (very short in the P. nigrolineata and P. latecincta groups) and without such setae in Crossoglossa. In subgenus Crossoglossa (Fig. 3 A), lateral lobes extremely large, with inner margins nearly straight and outer margins fully arcuate; apices of lateral lobes widely rounded and extended well beyond the very narrow epilobes. In subgenera Parena and Bothynoptera (Figs 3 B, 3 C, 3 D), lateral lobes relatively short, with inner margins more or less oblique and outer margins nearly straight or arcuate, and the epilobes relatively wide; apices of lateral lobes narrowly rounded or slightly angulate, only slightly extended beyond the epilobes in subgenus Parena (Fig. 3 B), but the epilobes extended beyond the lateral lobes (Figs 3 C, 3 D) in subgenus Bothynoptera. Glossal sclerite apically truncate, with two to four pairs of setae, the paramedian pair longer than the others. Paraglossae fused to the glossal sclerite, with apices membranous and setose. Terminal labial palpomeres fusiform or subcylindrical, similar in both sexes. Terminal and penultimate labial palpomeres shortly setose, the penultimate palpomere with two long setae on the inner margin and one on the dorsal apex. Submentum with two setae on each side in most species, with the outer one much shorter than the inner one. However, there is only one long seta on each side of submentum in P. heteronycha sp. n. Pronotum: Pronotal shapes are varied among species: nearly rectangular to distinctly transverse. The pronotum of the subgenus Crossoglossa is often wider (PW / PL = 1.50 – 1.82, generally greater than 1.60) than in other two subgenera, and that of the subgenus Bothynoptera is often narrower (PW / PL = 1.19 – 1.43, generally less than 1.35). The pronotum is much wider than the head (PW / HW = 1.05 – 1.26, generally greater than 1.10) in the subgenus Crossoglossa, narrower or barely wider than the head (PW / HW = 0.85 – 1.13, generally less than 1.10) in the other two subgenera. Anterior margin nearly straight or weakly emarginate at middle, without distinct apical angles. Posterior margin nearly straight at the middle, and more or less oblique laterally. Maximum width of pronotum near the anterior third, but in some species of subgenus Bothynoptera (e. g., P. heteronycha sp. n.), distance between posterior angles is almost equal to the maximum width. Lateral margins more or less sinuate before posterior angles in most species, with two marginal setae, at the maximum width point and the posterior angle, respectively. Posterior angles narrowly rounded or faintly angulate at an obtuse or rectangular angle in most species, but not denticulate. The lateral explanations more or less widened. Basal foveae shallow and wide, without distinct limits. Disc moderately convex, glabrous or finely and sparsely punctate, sometimes faintly wrinkled. Median line fine, slightly deepened anteriorly and posteriorly in some species. Elytra and hind wings: Elytra broad and slightly widened apically. Humeri distinct, widely rounded, without a humeral denticle. Basal ridge incomplete, extended medially only to base of the fourth stria. Elytral disc with a pair of large and shallow depressions near the middle of the interval 3 in many species, absent from several species belonging to different subgenera. In ground plan, the discal depressions are elongate or subtriangular, occupying intervals 3 to 6 and one-third to half of the elytra length. Lateral margins are usually shallowly depressed near the basal third. Intervals 7 and 8 more or less tumid near the apex and elytral surface otherwise even; but in P. heteronycha sp. n., humps are present on the base and middle parts of the lateral intervals. Scutellar striae present on interval 1, of similar depth as normal striae, usually with free apex. Basal pore (bp) present adjacent to stria 1, slightly anterior to apex of scutellum (sa). Interval 3 has three discal setigerous pores (except P. dorsigera) with the basal two (d 1, d 2) adjacent to stria 3 and the apical one (d 3) next to stria 2. In P. dorsigera, one additional discal pore (with two or three as individual variants) is present between d 2 and d 3 adjacent to stria 2. Discal pores simple, with their diameter less than half of the interval width (Fig. 4 D) in most species, but are strongly enlarged forming foveae greater than interval width in P. dorsigera (Fig. 4 E), or forming black umbilicular spots in P. heteronycha sp. n. (Fig. 4 F). In subgenera Crossoglossa and Parena, d 1 very close to the elytra base, on the level only slightly posterior to the apex of scutellum. Thus the distance between d 1 and bp is subequal or slightly less than the distance between bp and sa (Figs 4 A, 4 B, 4 C). In contrast, in the subgenus Bothynoptera, d 1 is distant from the elytra base, on a level much more posterior to the apex of scutellum. Thus the distance between d 1 and bp is about two times the distance between bp and sa (Figs 4 D, 4 E, 4 F). Intervals 5 and 7 are without discal pore on most species, but in a few individuals of P. dorsigera, there is one pore near the middle of interval 5. Elytra striae not or shallowly incised, finely punctate. Intervals flat or slightly convex, with very fine and sparse punctures arranged in an irregular row in most species. Stria 7 with one pore near elytral apical margin. The interval 9 less than half-width of the preceding ones. Umbilicular series composed of 18 – 28 pores. In the truncatipennes groups of Carabidae, the elytral apex is referred to as the apical truncation, although it is not always evidently truncate. The elytral apex is distinctly truncate in most members of the subgenus Crossoglossa, with the sutural angles usually more or less pointed (Figs 14 A – G), except for P. sciakyi sp. n. (Fig. 14 H), and the outer apical angles well rounded or weakly angulate (Figs 14 I – L). In the subgenera Bothynoptera and Parena, the elytral apex is subtruncate in most species, with the sutural angles not pointed and the outer apical angles well rounded (Figs 5 A, 5 E). However, in three species groups (P. heteronycha, P. dorsigera, and P. scutata groups), the apex is distinctly truncate, with the apical margin nearly straight or slightly concave. In the P. heteronycha and P. scutata groups, the sutural angles are more or less denticulate (Figs 5 B – D, 5 F). In the P. heteronycha and P. dorsigera groups, the outer apical angles are prominent but apically rounded (Figs 5 F – J). Hind wings are fully developed, with large oblongum and wedge cells. (Fig. 6 A) Legs: Metacoxae with two long setae, near ante-lateral and post-lateral corners, and numerous shorter setae. Pro- and mesotrochanters each with one long seta near the apex. Metatrochanters with one long seta near the middle. All femora with four or more setae along the ventral surface. Cleaning organ of the protibiae with two cleaning setae and a well-defined cleaning spur very close to the inner margin (Fig. 6 H). Mesotibiae of males smooth on the ventral surface, without a notch or denticle. All tarsomeres strongly widened, with tarsomere 1 of all legs and metatarsomere 2 cylindrical, pro- and mesotarsomere 2 and tarsomere 3 of all legs subtriangular to cordate, and tarsomere 4 bilobed. Metatarsomere 1 slightly longer than metatarsomere 2. Tarsomeres sparsely setose dorsally. In all species of the genus, the ventral surfaces of protarsomeres 1, 2, and 3 have biseriate adhesive setae along their full length. However, the adhesive setae on the ventral surface of male mesotarsomeres are always present but varied: the apical half of mesotarsomere 1 has biseriate adhesive setae on its apical portion (Fig. 6 I) in many species, but these setae are absent from most species of the subgenus Bothynoptera (except for P. taiwana) and some species of the subgenus Parena (P. latecincta, P. monticola, P. politissima, P. fulva sp. n., and P. plagiata) (Fig. 6 J), or rudimentary (i. e., present as a single row near the apex) in P. circumdata. The ventral surface of mesotarsomere 2 has biseriate adhesive setae along its full length or nearly so in most species, but they are restricted to the apical half in some species of subgenera Parena (P. politissima, P. latecincta, P. circumdata) and Bothynoptera (P. kurosai, P. quadrisignata, P. gonggaica sp. n., P. triguttata sp. n.). The ventral surface of mesotarsomere 3 has well-developed biseriate adhesive setae except in P. politissima. Variation in the male mesotarsal adhesive setae in different species of genus Parena is summarized in the diagram in Fig. 7. Tarsal claws strongly pectinate, each with six to ten long pectinations (the medial one much smaller than others in some specimens) with the proximal one very close to the claw base (Figs 6 D – G). However, in the related genera Pachycallida and Metallica, there are four or five pectinations on each claw with the proximal one slightly distant from the claw base (Figs 6 B, 6 C). In the same individual, there can be a difference of one pectination between claws in same or different legs. The tarsal claws are usually symmetric or nearly so, but conspicuously asymmetric in P. heteronycha sp. n. (Figs 6 F, 26 E – G). In the latter species, the inner claws of meso- and metatarsi are longer than the outer ones (the outer claws of prolegs are homologous to the inner claws of meso- and metalegs, thus the claws of prolegs are in an opposite form), with all pectinations restricted to the basal half of claw and shorter than those on the outer claw. The apical half of the inner claw is smooth and elongated. The outer claw is the same as in other species. Venter: Pro- and mesothoracic venter glabrous or sparsely setose, metathoracic venter finely setose overall. Abdominal sternites each with numerous fine setae in addition to the primary setae. The abdominal sternite VII (terminal ventrite) with two or three primary setae (one or four in some specimens) on each side in both sexes. Apex of sternite VII of females straight in most species of the genus (Fig. 8 A), but weakly projected in P. mellea and P. cruralis (Figs 8 C, 8 D) and more distinctly projected in P. sulawesiensis (Fig. 8 B). Apex of sternite VII of males straight (Fig. 8 E) in most species of subgenera Crossoglossa and Bothynoptera, but distinctly emarginate in P. mellea (Fig. 8 F). In most species of subgenus Parena, apex of sternite VII of males is weakly emarginate (Fig. 8 H), but obviously emarginate (Figs 8 I, 8 J) in P. fasciata and P. andrewesi, or nearly straight (Fig. 8 G) in P. monticola, P. circumdata, and P. fulva sp. n. Male genitalia: Median lobe of aedeagus slightly bend near the base with shape varied. Relatively slender (AL / AW = 5.4 – 6.8) in subgenus Crossoglossa; very stout (AL / AW = 3.4 – 4.2) in most members of subgenus Bothynoptera, but only moderately stout (AL / AW = 4.5 – 5.1) in the P. tesari group, or slender (AL / AW = 5.5 – 6.0) in the P. taiwana group; varied from very to moderately stout (AL / AW = 3.7 – 5.6) in subgenus Parena. Apical orifice oriented toward the left or ventral-left side of the aedeagus. Apical lamella (the apical portion between the extreme apex and the apical orifice) laminar or relatively thick, often slightly bent toward dorsum in lateral view; right margin often more or less sinuate basal to the apical lamella in dorsal view. The endophallus has distinct sclerites and scaled regions, without large spines (compared to those in Metallica and Pachycallida), with a long flagellum-like sclerite in many species, but not pointed out to the apical orifice (as in Euproctinus). A total of four groups of structures are recognized on the endophallus. These structures exist in all species of the genus but differ in their shape. (1) Primary sclerite (blue in Fig. 9) is a heavily chitinized piece, extended from the base of median lobe. It is composed of a flared basal expansion and an elongated flagellum-like apex in most species of subgenera Parena and Bothynoptera (Figs 9 A, 9 D). The flared expansion is reduced in the P. bicolor group, thus the primary sclerite is filiform in these species (Fig. 9 C). The flagellum is thick and extended to the apical orifice, as in P. kurosai (Fig. 30), or thinner and gradually tapered and terminated before apical orifice such as P. tripunctata (Fig. 9 A). The primary sclerite is rudimentary in the subgenus Crossoglossa and is present as a very small triangular piece near the base of median lobe (Fig. 9 B). (2) Apical sclerite (magenta in Fig. 9) is a V-shaped (in subgenera Parena and Bothynoptera, Figs 9 A, 9 C, 9 D) or ribbon-form (in subgenus Crossoglossa, Fig. 9 B) piece near the apical orifice. It is less chitinized than the primary sclerite. Sometimes the major portion of the apical sclerite is weakly defined (such as in P. kurosai), but its left edge is always well chitinized. The basal core refers to the darkest area near the base of the apical sclerite which is usually heavily scaled. It is usually ovate or strongly elongated, but extended as a transverse scaled belt as in P. fulva (Fig. 75), or indistinct as in P. kurosai (Fig. 30). (3) Squamate sheath (green in Fig. 9) is the large scaled membranous portion extended from the base of median lobe to the apical orifice. It usually surrounds the apical part of the primary sclerite. There is a gap in the middle of the squamate sheath, dividing it into a basal sheath and an apical sheath. The apical sheath is usually much larger and more heavily scaled than the basal sheath. (4) Squamate sac (yellow in Fig. 9) refers to the small scaled sac present on the basal half of median lobe, well separated from the squamate sheath. It is usually on the dorsal side to the squamate sheath, sometimes turns to the right or left side. The squamate sac is simple (such as in P. malaisei, Fig. 44) or divided into two sacs (such as in P. tripunctata, Fig. 9 A): The proximal sac is usually like a scaled membranous sac (Fig. 9 D) but sometimes has a dentate chitinized apex as in P. bicolor (Fig. 9 C). The distal sac is usually the same size as the proximal one, but less chitinized. Left paramere large and rounded, with concave outer surface and rounded or slightly truncate apex. The right paramere is smaller than the left and trifurcate with the apex varied (Fig. 10). The parameres have very little taxonomical value in the genus Parena because they are similar among different species and the apices are somewhat varied infraspecifically. Female genitalia: Gonocoxite I of ovipositor without setae or spines, with its dorsal surface strongly concave in subgenus Crossoglossa, shallowly concave in subgenera Parena and Bothynoptera. Gonocoxite II subquadrate or dichotomous, with four to seven ensiform setae on the apex, without nematiform seta or membranous apical extension. In subgenus Crossoglossa, gonocoxite II dichotomous and strongly bent outwards forming a U-shaped structure (Figs 11 Y – γ). The inner branch with two ensiform setae on the apex. The outer branch slightly longer than the inner one in the P. laesipennis group (Fig. 11 Z), and similar length in the other two groups. It with two or three ensiform setae on the apex, of similar length to those on the inner branch in the P. testacea group (Figs 11 α – γ) and much shorter in the other two groups (Figs 11 Y, 11 Z). In subgenera Parena and Bothynoptera, gonocoxite II quadrate or nearly so, with the apex concave, nearly straight, or slightly convex (Figs 11 A – X). The apex with an evident tooth near the inner angle (e. g., Fig. 11 O) in many species, but the tooth very faint in most species of Bothynoptera and in P. fulva sp. n. (e. g., Fig. 11 U). The ventral surface of gonocoxite II with a large depression (e. g., Fig. 11 S) in most species, but the depression very shallow in subgenus Bothynoptera and in the P. scutata group of subgenus Parena (e. g., Fig. 11 V). The apex with four to seven ensiform setae. In most species of subgenus Bothynoptera, these setae are subequally arranged with two or three of them grouped on the outer angle (e. g., Fig. 11 B); but in P. kurosai and P. tesari (probably also P. obscura), there are three or four ensiform setae grouped on the inner and outer angles, respectively (Figs 11 C, 11 D). In most species of subgenus Parena, there are two or three ensiform setae on the outer angle, two on the inner angle, and another one next to the apical tooth (e. g., Fig. 11 N); but in P. fulva sp. n., these setae are nearly equally spaced except the inner two slightly close to each other (Fig. 11 U). In the P. bicolor group, P. scutata group, and the other two species of the P. stigmatica group, all of these setae are grouped to the inner and outer angles (e. g., Fig. 11 K), but one seta of each group may be slightly distant from others (e. g., Fig. 11 W) in some species. Female internal reproductive tracts are similar among different subgenera of Parena (Fig. 12). Spermatheca digitiform without a differentiated pedicel, strongly whorled on the surface of the apical half, inserted on the dorsal surface of bursa copulatrix close to the junction of common oviduct. Spermathecal gland similar in length to spermatheca, more or less branched near base, inserted to the lateral side of spermathecal base. The tubular sac slender and much longer than spermathecal gland, inserted near the base of spermathecal gland. Monophyly and relationships. The subtribe Metallicina was erected by Basilewsky (1984) for Metallica, Pachycallida and Parena. Soon after that, Euproctinus was included in Metallicina as well (Shpeley, 1986). As the result of a preliminary phylogenetic analysis (Shpeley, 1986), the monophyly of the subtribe Metallicina can be suggested by the following synapomorphic character states: antennomeres 5 – 11 each with ventral sensory pits; apex of glossal sclerite with four or more apical setae; head with suborbital setae; antennomere 1 with a carina. Within the subtribe Metallicina, the genus Parena is presumed to be the sister group of Metallica + Pachycallida, supported only by one synapomorphic character state: the retinacular ridge of right mandible reduced. Nevertheless, this relationship seems reliable as it fits the zoogeographical pattern as well. The monophyly of genus Parena could be supported by the following apomorphic character states: (1) male genitalia with endophallic sclerite; (2) gonocoxite II of ovipositor with four or more ensiform setae, without membranous apex or trichoid setae; (3) female reproductive tracts with extremely long tubular sac. Three subgenera are recognized under the genus Parena. The monophyly of two subgenera (Crossoglossa and Bothynoptera) seems to be well supported, whereas the third (Parena s. str.) could be paraphyletic. Detailed discussions on the infrageneric relationships are provided under each subgenus. Life history and larvae features. Adults of Parena can be found on leaves or trunks of various woody plants. They are frequently collected by beating dense vine plants or dead leaves hanging on small trees. They might be hidden inside the dead leaf rolls in the daytime and active at the night preying mainly on lepidopteral larvae. Many species are attracted by lights, whereas a few very rare species of the subgenus Bothynoptera were only collected from the canopy of trees with height between 5 and 8 m. Based on the literature by Andrewes, Habu, Yokoyama, Nawa, Minamikawa, etc., Habu (1967) reviewed the life history of some common Japanese species: the adults of P. nigrolineata nipponensis (= P. nigrolineata) are reported to prey on various lepidopteral larvae including the silk worm (Bombyx mori L.); the larvae of P. perforata (= P. dorsigera) are predatory on Spilosoma imparilis Butler (Arctiidae); P. cavipennis is predaceous on Phrixolepia sericea Butler (Heterogeneidea); the adults of P. tripunctata were found in the leaf-rolls of Paroplapoderus pardalis Vollenhoven (Attelabidae, Coleoptera), but it remains to be proven whether or not they feed on the weevils. More recently, Habu (1981) reported that P. cavipennis is predaceous on Scopelodes contracta Walker (Heterogeneidae). Mochizuki (1990) reported that P. laesipennis feeds on larvae of Pidorus glaucopis (Drury) (Zygaenidae). In India, P. nigrolineata was reported as a predator of Opisina arenosella Walker (Oecophoridae), the coconut caterpillar (Mohamed et al., 1982; Pushpalatha & Verresh, 1995), Nephopteryx eugraphella Ragonot (Pyralidae), the chiku moth (Sran & Sandhu, 1979), and Atteva fabriciella Swederus (Yponomeutidae), the ailanthus webworm (Misra, 1994). In China (Shandong) and Korea, P. cavipennis was reported as an important predator of Hyphantria cunea (Drury), the fall webworm (Ko & Ko, 1982; Wang et al., 1999). Both adults and larvae can attack larvae of the webworm. Zhao et al. (2011) reported P. cavipennis as a predatory natural enemy of Antheraea pernyi (Guérin-Méneville), the tussah silkworm, in Liaoning province. Larvae of the beetle bite the ventral side of the silkworm, sucking its body fluids and causing death in days. P. cavipennis was also reported as predaceous on larvae of various lepidopteral pests, including twenty-eight species belonging to ten families, and Arge captiva (Smith) (Argidae, Hymenoptera) (Zhou, 1988; Zhao et al., 2011). P. latecincta was reported as predaceous on Termioptycha bilineata (Wileman) (Pyralidae), an important pest on the staghorn sumac in Beijing. Both larvae and adults of the beetle can attack pyralid moth larvae inside their leaf rolls (Zhao et al., 2014). In China (Liaoning), P. cavipennis hibernates in the adult stage in dry habitat under trees, such as under dirt clumps, rocks, or dead leaves. Adults are active between May and October. The egg stage starts from middle July, lasting about five days. The average stadia of larvae, prepupa and pupa are 9 – 12 d, 2 – 3 d, 8 – 10 d, respectively (Zhao et al., 2011). Larvae of some East Asian species have been illustrated and described by different authors: Habu et al. (1963) for P. nigrolineata nipponensis (= P. nigrolineata); Habu & Sadanaga (1967) for P. perforata (= P. dorsigera); Habu (1981) for P. cavipennis; Hondo (2012) for P. tripunctata; and Zhao et al. (2014) for P. latecincta. Diversity and biogeography The genus Parena is composed of 46 species classified into three subgenera. This genus has an extensive distributional range in the Old World Tropics, from West Africa eastward through Madagascar, India, and Indochina to the Malay Archipelago, and easternmost to New Caledonia and Samoa; southward to the eastern coastal region of Australia; and northward through East Asia to Primorye, Russia. The specific diversity of genus Parena from Asia is far richer than that from Africa or Australia. The highest species richness occurs in south China and on the south slope of the Himalayan Range (Map 1). For example, in some regions (e. g., southern Yunnan and Taiwan) of southern China, as many as thirteen species occur in an area of no more than ten thousand square kilometers. Among the three subgenera of Parena, the nominotypical subgenus has the widest distributional range, reaching from Africa and Australia. The other two subgenera are confined to the Oriental Realm, the eastern part of Palaearctic Realm, and Papua New Guinea. The subgenus Crossoglossa is most diverse in the Malay Archipelago, and the subgenus Bothynoptera ranges farther north with its highest diversity in south China. Members of some species groups have strictly allopatric distributions, showing examples of geographical replacement. For example, in the P. tesari species group (Map 7), P. tesari (Jedlička) is widely distributed in south China, while its adelphotaxon, P. obscura Mateu, is only from Bhutan and Nepal. In the P. nigrolineata species group (Map 10), P. nigrolineata (Chaudoir) is widely distributed in the area west to Weber's Line, while its adelphotaxon P. picea (Macleay) is from the area east of Weber's Line. In the species groups of P. laesipennis, P. testacea, P. scutata, and P. plagiata, all species are strictly allopatric with some very widely distributed and others restricted to small areas. Although some species are very common and widely distributed (e. g., P. nigrolineata from Asia, and P. africana from African Continent), several species in the genus are relatively rare in collections. Some of these rare species are very narrowly distributed (e. g., P. picipes sp. n. and P. pendleburyi Andrewes are endemic to north Borneo, and P. heteronycha sp. n. is endemic to north Laos). A few species are only known from the holotype material (e. g., P. gonggaica sp. n. from Sichuan, and P. dorae Basilewsky from Angola), however some others are relatively widely distributed but still known from only very few specimens (e. g., P. monticola Shibata from China, and P. fulva sp. n. from Southeast Africa). It seems to be very difficult to collect these rare species on low vegetation, because individuals of some species (e. g., P. emarginata sp. n. from China) of the subgenus Bothynoptera were only collected from the canopy of medium-sized trees, by using a long-stick sweeping net. Species excluded from genus Parena Andrewes (1947) described Bothynoptera sticta based on four specimens collected from Kambaiti in Burma. This species was mentioned by Jedlička (1963) but its taxonomic status has not been discussed after that. In recent catalogues (Lorenz, 2005; L ̂ bl & L ̂ bl, 2017), it was placed in the genus Parena. A few years ago, the senior author examined one paratype (Fig. 13 B) of this species in NHML, and later, the holotype (Fig. 13 A) and another paratype deposited in NHRS were examined through photos thanks to the help of Dr. J. Bergsten. Based on these, we found that this species is different from all members of the genus Parena in the following aspects: (1) mandibles not widened, outer margins nearly straight; (2) interval 3 of elytra with only two setigerous pores; (3) terminal palpomeres acuminate to apex; (4) eyes not hemispheric, much less convex than other species of Parena; and (5) metatarsomere 1 longer than the combination of following two tarsomeres. Although we didn’t study the ventral or genital characters of this species, all the above character states support well that this species actually belongs to the genus Peliocypas Schmidt-Ĝbel. We propose the new combination herein: Peliocypas stictus (Andrewes, 1947) comb. nov.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

03877623625EFFF92DEFB341FA7B5FA2.taxon	description	Crossoglossa was erected by Chaudoir (1872) to accommodate his three species without considering the earlier name Parena Motschulsky, 1860. The name Crossoglossa was then widely used, and several species were described under that name (e. g., Bates, 1873; Alluaud, 1917). However, the type species of Crossoglossa was not fixed until Jeannel (1949) designated Crossoglossa testacea Chaudoir for it. The concept of Crossoglossa (sensu Bates, 1873; Alluaud, 1917) was similar to the genus Parena at present until Andrewes (1919, 1928) synonymized it with Phloeodromius and Parena. Thereafter, Crossoglossa was used as a subgenus name in different concepts (Jeannel, 1949; Jedlička, 1952). In the present study, Crossoglossa is treated as a subgenus of Parena to accommodate species related to P. testacea, which are different from members of the other two subgenera of the genus in the following unique character states: (1) pronotum much wider (PW / PL 1.50 – 1.82) than other species of the genus; (2) mentum without setae, lateral lobes extremely large, inner margin nearly straight, epilobes very narrow (Fig. 3 A); (3) male genitalia rather slender, endophallus with the primary sclerite rudimentary; (4) gonocoxite II of ovipositor dichotomous. The present concept of the subgenus Crossoglossa is similar to that of Jedlička (1952), containing nine species distributed through East Asia, all parts of the Oriental Realm, Papua New Guinea, and easternmost to the Solomon Islands. They are not known from Africa or Australia. Three species groups are recognized in the subgenus, each of them containing one or several strictly allopatric species. The exceptional male and female genital characters suggest Crossoglossa is monophyletic. However, its relationship in the genus Parena is difficult to infer before a comprehensive phylogenetic analysis is conducted. Based on the modified male and female genitalia, Crossoglossa is considered to be a highly specialized group in the genus.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

Crossoglossa cavipennis Bates: This species was originally described from an unspecified number of specimens from " Hiogo ", but more than one specimen was implied. In the collection of MNHN and NHML, a total of three specimens from Bates's collection are perfectly in accord with the original description. We herein designate the one deposited in MNHN bearing Bates's handwriting label (Fig. 15 A) as the lectotype. Parena rufotestacea Jedlička: The holotype (NMPC) and paratype (NHML) examined herein are perfectly in accord with the original description. They are all identical to P. cavipennis. P. laesipennis with dark color from southwest China and Southeast Asia was misidentified as P. rufotestacea by Xie & Yu (1993) at first and then applied in later literature (Kirschenhofer, 2006; Park et al., 2006).	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

03877623625DFFFD2DEFB2ECFA7A5EB0.taxon	diagnosis	Comparisons. P. cavipennis is similar to and sympatric with P. laesipennis, but can be readily distinguished from the latter species by: (1) elytral striae well incised, intervals slightly convex (in P. laesipennis elytral striae not incised, replaced by rows of fine punctures, intervals almost flat); (2) elytral sutural angles very faintly pointed, outer apical angles fully rounded (in P. laesipennis sutural angles sharply pointed, forming short spines, outer apical angles weakly angulate); (3) LL subequal to LW (in P. laesipennis LL more than 1.5 times LW). Besides above, for Japanese specimens, P. laesipennis is usually much larger than P. cavipennis; and for Chinese specimens, P. laesipennis is usually much darker than P. cavipennis. Despite the very different external features, P. cavipennis is similar to P. testacea in their male genitalia, in particular for the shape of the apical lamella. However, in P. cavipennis, the dorsal and ventral margins of the median lobe are parallel before apical orifice, and then abruptly narrowed to the apex. While in P. testacea, the dorsal and ventral margins are not parallel, but gradually attenuate from base to apex.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

03877623625DFFFD2DEFB2ECFA7A5EB0.taxon	description	Description. Body length 8.8 – 10.5 mm. Dorsum yellowish brown; basal three antennomeres, and basal half of antennomere 4 yellow, remainder of antennae nearly black; venter yellowish brown. Pronotum strongly transverse, PW / PL = 1.58 – 1.66, much wider than head, PW / HW = 1.13 – 1.19; widest at anterior third, lateral explanations very wide. Elytra without microsculpture; striae shallow, but well incised, finely punctate; intervals slightly convex, very finely and sparsely punctate; disc depressed near middle of third to sixth intervals; apices subtruncate, outer apical angles completely rounded; sutural angles very faintly pointed, without distinct tooth. Median lobe of aedeagus with dorsal and ventral margins parallel before apical orifice, and then abruptly narrowed to apex; apical lamella slightly narrowed to apex, LL subequal to LW, apex rounded. Endophallus (Fig. 16) very coarsely scaled on basal sheath, base of apical sheath subquadrate in dorsal view; squamate sac not divided, situated on basal fifth of median lobe, right to squamate sheath. Gonocoxite II of ovipositor dichotomous, inner branch with two long ensiform setae apically, outer branch with three ensiform setae apically, much shorter than those on the inner branch (Fig. 11 Y).	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

This species is widely sympatric with P. laesipennis in south China, but much more common in eastern provinces of China and less common in Taiwan and southwest China. Kirschenhofer (1994: 1023) reported P. cavipennis from Nepal. However, we only examined specimens of P. laesipennis from Nepal and adjacent regions (N. India, S. Xizang), but P. cavipennis were not seen. Probably his record was based on the misidentification of P. laesipennis. P. cavipennis was erroneously reported from Indonesia without specific specimen examination (Xie & Yu, 1993). Their record is far from all confirmed records of this species.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

038776236259FFC12DEFB3A0FF175A8D.taxon	discussion	Notes on types. This species was originally described from an unspecified number of specimens from " Nagasaki ", but more than one specimen was implied. In the collection of MNHN, a total of two specimens from Bates's collection accord with the original description. We herein designate the one bearing Bates's handwriting label (Fig. 17 A) as the lectotype. We also examined a female in NHML labeled as " type ", with a determination label not in accord with Bates's handwriting, and the locality " Hiogo " different from the type locality in the original description. Thus, this one is considered to be mislabeled as type and excluded from the type series.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

China (Zhejiang, Hunan, Fujian, Guangdong, Hainan, Chongqing, Yunnan, Xizang, Taiwan), Japan, South Korea, Vietnam, Laos, Thailand, Myanmar, Malaysia, India (Darjeeling), Nepal. Geographical variation. The southwestern specimens (from southwest China, Laos, Thailand, Nepal, and India, Figs 17 C – D, 18 A, 18 B, 19 A, 19 C) of P. laesipennis are slightly different from the typical specimens (from Japan and Taiwan, Figs 17 A – B, 19 B). They are usually slightly darker and smaller sized (9.5 – 11.0 mm versus 11.0 – 12.6 mm), and with elytral microsculpture less obvious. The male genitalia also differ slightly as well: in the southwestern specimens, the apical lamella is generally slightly more bent to the dorsum, and the ventral margin is slightly more curved in lateral view. However, the above differences are subtle, not always stable, and intermediate status is present in some individuals from Eastern China. Therefore, we believe that the above characters gradually vary by distance from northeast to southwest, and that all the above populations should be classified as the same species.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

03877623626EFFC92DEFB48BFEE75CF7.taxon	diagnosis	Comparisons. P. mellea is distinguishable from the other four species in this species group by the combination of: elytra with sutural angles shortly pointed, forming small denticles; outer apical angles almost rounded; elytra without black patch; tibiae yellowish brown. This species is similar to P. testacea, especially for those specimens from Sumatra and the Philippines, which have the same antennal color as P. testacea. These two species are distinguishable by: (1) elytral sutural angles only slightly pointed, forming small denticles in P. mellea, but sharply pointed forming long spines in P. testacea; (2) elytral outer apical angles less distinct in P. mellea; (3) in P. mellea, elytra intervals with punctures much sparser, and stria with puncture rows more clearly defined; (4) in P. mellea, apex of abdominal sternite VII notched in males (Fig. 8 F), and projected in females (Fig. 8 C), but straight in both sexes of P. testacea; (5) apical lamella of aedeagus longer in P. mellea. Some specimens of P. mellea are similar in color to P. sulawesiensis, especially for those from the Maluku Islands. These two species are different in (1) elytral sutural angles only slightly pointed forming small denticles in P. mellea, but sharply pointed forming long spines in P. sulawesiensis; (2) in P. mellea, apex of abdominal sternite VII more distinctly notched in males, and less projected in females than in P. sulawesiensis; (3) apical lamella of aedeagus ovate in P. mellea, but subrectangular in P. sulawesiensis.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

Specimens from Borneo are somewhat different from the holotype from Java. They are much larger (ca. 11 mm vs 9.6 mm) and elytra disc with very shallow depressions in the middle of intervals 3 to 6 (without depression in the holotype). Based on their similar leg color, we determine them all as P. cruralis.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

03877623626CFFC82DEFB681FC455FF3.taxon	discussion	Remarks. P. cruralis was originally described as a variety of P. testacea, and recently (Lorenz, 2005) treated as a subspecific name under P. testacea. However, after the examination of the holotype, we found that P. cruralis is closer to P. mellea than to P. testacea for the similarities in elytra apices and interval punctures. The taxonomic position of P. cruralis is still doubtful because the male is unknown. We treat P. cruralis as a separate species for now because it is markedly different from other species in coloration.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

Later, some Parena species with relatively narrow pronotum were described under this genus (Bates, 1873, Andrewes, 1947, Jedlička, 1951). In Jedlička's monograph (Jedlička, 1963), Bothynoptera was regarded as a separate genus including six species, and distinguished from Parena by the differences in tempora length and pronotum shape. However, the generic characters mentioned are not in accord with all of these six species. Habu (1967) pointed out that Bothynoptera has no generic differences from Parena, and synonymized these two genera. In the present study, we find the following important diagnostic characters supporting a new concept of subgenus Bothynoptera: (1) first setigerous pore on elytral interval 3 distant from elytra base, on a level much behind scutellar apex (Figs 4 D, 4 E, 4 F); (2) male mesotarsomere 1 without adhesive setae ventrally (Fig. 7) in most species; (3) antennomeres 1 – 3 with well-developed accessory setae (Fig. 1 B). (4) mandibles rounded-triangular, less widened than in the other two subgenera (Fig. 2); (5) retinacular ridge of right mandible shortened but not reduced to a retinacular tooth (Fig. 2); (6) apex of mentum epilobes extending slightly beyond lateral lobes (Figs 3 C, 3 D). The above character states differentiate subgenus Bothynoptera from other members of Parena and are thought to be synapomorphies supporting the monophyly of the subgenus. In addition to the above characters, the following characters present in subgenus Bothynoptera probably have taxonomical importance as well: dorsum not metallic; pronotum relatively narrow; elytra discal depressions very shallow or absent; apex of abdominal sternite VII straight in both sexes; male genitalia in stout form in most species. Most of these above character states are only present in subgenus Bothynoptera and distinguish this subgenus. However, the second character state (adhesive setae absent from male mesotarsomere 1) is also found in five species (P. latecincta, P. monticola, P. politissima, P. fulva sp. n., and P. plagiata) of subgenus Parena. Based on several other important differences, including the pronotum relatively wide, postgenae without a long seta, terminal ventrite slightly emarginate, and the first pore on elytral interval 3 very close to elytra base, these species are considered not to be related to species of Bothynoptera. Subgenus Bothynoptera contains fourteen species, mainly distributed in East Asia, and many of them have relatively wide distributional ranges. China has the most diverse fauna of the subgenus, with twelve species recorded: five of them are endemic to China, five have ranges extended to the south slope of the Himalayan Range and the north part of Southeast Asian counties, and four species range Japan, Korea, and the Russian Far East. The subgenus Bothynoptera is not found in Africa, Australia, South India, or the Malay Archipelago. Five species groups are recognized in the subgenus, based mainly on differences in male genitalia (except for P. heteronycha for which male genitalia are unknown). The P. tripunctata species group has the highest species diversity, including eight species with very similar stout male genitalia. The P. taiwana group (containing only one species) is the most atypical in the subgenus for the presence of ventral adhesive setae on male mesotarsomere 1 and rather slender male genitalia; but based on the character states mentioned above, it should be assigned to the subgenus Bothynoptera.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

038776236274FFD52DEFB2ECFB945EFF.taxon	discussion	Notes on types and synonyms. Bothynoptera dorsigera Schaum: This species was originally described from a single specimen from Northern India. The female we examined in the collection of MNHU in accord with the original description is the holotype. Bothynoptera perforata Bates: This species was originally described from three specimens from Hiogo. We found two specimens in the collection of MNHN and NHML in accord with the original description. We herein designate the male deposited in MNHN bearing Bates's handwriting label (Fig. 27 B) as lectotype. As indicated in the original description (Bates, 1873), B. perforata is different from B. dorsigera in having the pronotum wider, elytra without yellow patch and the dorsum a lighter color. However, as discussed below, all these differences are considered as geographical variations, and specimens with intermediate features occurs in several localities of China. So, B. perforata is treated as a junior synonym of P. dorsigera herein. Parena nepalensis Kirschenhofer: In the original description (Kirschenhofer, 1994), this species was compared only with P. andrewesi Jedlička but not with any species previously placed in Bothynoptera. We did not examine the type of this species. However, from the original description and illustration, it is identical to the holotype of P. dorsigera and other specimens examined from Nepal (Fig. 27 D). So, we synonymize it with P. dorsigera (Schaum) herein. Parena kunmingensis Kirschenhofer: The original description (Kirschenhofer, 1996) pointed out that this species is very similar to P. nepalensis, and has small differences in pronotum shape, elytral pore size, and shape of elytral apices. As discussed below, these differences are considered as geographical variations. Thus, we synonymize this species with P. dorsigera (Schaum) herein.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

P. dorsigera is easily distinguishable from all other species of the genus in having four (occasionally five or six) very large setigerous pores on elytral interval 3. In the subgenus Bothynoptera, P. kurosai and P. tesari are somewhat similar to P. dorsigera in their relatively large body size and dorsum dark brown without a patch, but differ in having elytral interval 3 with only three discal pores. P. tesari also different from P. dorsigera in having the elytral apices evenly rounded.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

China (Beijing, Henan, Shaanxi, Zhejiang, Hunan, Guangxi, Sichuan, Yunnan, Xizang, Taiwan), Russia (Primorye), Japan, South Korea, Vietnam, Laos, Nepal, North India. Geographical variation. This species has a wide distributional range in East Asia, northeast to Japan and southwest to Nepal (Map 6). Its external features vary geographically in the following aspects: (1) Coloration: the dorsum is gradually darkened from north to south. In northern localities such as Japan, Russia, Korea, and North China, the dorsum is always reddish brown (Figs 27 B, 27 F); in southern localities such as Vietnam, Laos, and Taiwan, the dorsum is often piceous (Fig. 27 E), but dark brown individuals occur as well. In the western localities such as Yunnan, Nepal, and Sikkim, the dorum is usually dark brown to reddish brown (Figs 27 C, 27 D). (2) Elytra patch: the reddish yellow elytra central patch only presents in specimens from Nepal and North India (Fig. 27 D), such as the types of P. dorsigera and P. nepalensis. However, the background color of the elytra is light brown in some specimens, so that the patch is somewhat indistinct (Fig. 27 A). (3) Elytral apex: the elytral apical truncation is very distinct with prominent outer apical angles in this species. However, the shape of elytra apices varies slightly from northeast to southwest. In specimens from Japan and Primorye, the elytra apical truncation is bisinuate with the inner half curved outward and the outer half slightly concave inward (Fig. 5 J), as in the type of P. perforata. In specimens from northern and eastern China, the elytra apical truncation is often nearly straight (Fig. 5 I). In southern localities, such as Nepal, Vietnam, and southernmost China, the elytra apical truncation is strongly concave inward (Fig. 5 H). However, the degree of curvature gradually increases from north to south in China. Although these above differences are evident, we apply a wide species concept of P. dorsigera, without dividing it into subspecies, because these characters gradually vary by distance, and there is no significant difference in male genitalia among specimens from different localities (Figs 28, 29).	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

Specimens of P. kurosai from Japan are slightly different in having the elytral striae slightly incised, and the intervals slightly convex with denser punctures (Fig. 27 G). In contrast, specimens from the Asian mainland have the elytral striae not incised, and the intervals completely flat with very sparse punctures (Figs 27 H, 27 I). However, the male genitalia are almost identical between them (Figs 30, 31).	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

038776236270FFDB2DEFB18DFB015823.taxon	discussion	Remarks. P. kurosai is similar to P. dorsigera in the shape of the elytral apices and male genitalia, so we place them into the same species group. However, P. kurosai is also similar to P. tesari and P. obscura in: (1) abdominal sternite VII usually with three setae on each side; (2) gonocoxite II of ovipositor with ensiform setae grouped on outer and inner angles of the apex. These two characters are thought to be important because they are sexual and only present in these three species in subgenus Bothynoptera. Thus, it is inferred that these two species groups could be closely related. In addition, P. kurosai is unique in the genus in having an endophallus with a very large and thick apical flagellum of the primary sclerite, the apex of which is extended to the base of apical orifice.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

03877623627FFFDE2DEFB62EFDAD5E50.taxon	discussion	Notes on types and synonyms. Bothynoptera tesari Jedlička: This species was originally described from a single specimen from Karenko. The female we examined in the collection of NMPC in accord with the original description is undoubtedly the holotype. Parena esakii Habu: Kirschenhofer (2006) firstly proposed it is a synonym of P. tesari. We agree with this treatment according to the original description and illustrations. Parena nantouensis Kirschenhofer: We did not examine the type of this species. However, from the description and illustrations in the original description (Kirschenhofer, 1996), this species is almost identical to P. tesari except for its size (slightly smaller) and interval 3 with only two setigerous pores. We examined one specimen of P. tesari from Taiwan with two setigerous pores (the middle one missing) on the right elytron. Thus, we believe that the holotype of P. nantouensis is just an aberrant individual but not representing a separate species. Parena kataevi Kirschenhofer: This species was described from Hubei, Shennongjia. We examined specimens from Hubei and many other localities in central China that are in accord with it. Their male genitalia are identical to that of P. tesari from Taiwan. Thus, we treat P. kataevi as a junior synonym of P. tesari.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

This species ranges throughout southern China. Its external features vary slightly and geographically in the following aspects: (1) Coloration: Dorsum is gradually darker from north to south. In most parts of China, the dorsum is always reddish brown. In southern provinces such as Taiwan and Yunnan, the dorsum is often nearly piceous, but dark brown individuals occur there as well. (2) Elytra striae: For specimens from most localities of China, elytra striae are well incised and intervals slightly convex. However, for specimens from Yunnan and Vietnam (Fig. 32 D), the elytra striae are so shallow that striae 7 and 8 are hardly visible in the apical half. (3) Vertex setae: For specimens from mainland China and Vietnam, there is a pair of additional setae on vertex, which are shorter than the primary posterior supraorbital setae and placed posteromedial to them. However, such additional setae are absent from all specimens examined from Taiwan. Based on the above external differences, P. tesari can be divided into three populations: Taiwan, S. Yunnan + N. Vietnam, and other localities of China. We do not think they should be treated as subspecies because their male genitalia are almost identical (Fig. 34).	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

038776236278FFDD2DEFB73BFC925A2C.taxon	description	This species group contains only one species endemic in south China. It is characterized by: dorsum yellowish brown; antennae slender, extended beyond elytra base; retinacular ridge of right mandible about two-thirds length of terebral ridge (Fig. 2 D); elytra intervals strongly punctate; elytral apices evenly rounded; males with biseriate adhesive setae near the full length of mesotarsomere 1 ventrally; median lobe of aedeagus very slender (AL / AW 5.5 – 6.0), apical lamella thin; gonocoxite II of ovipositor nearly ovate, apex with six ensiform setae, two on each angle and two near the middle. This species group is unique in the subgenus for its males with adhesive setae on mesotarsomere 1 and male genitalia very slender. These two genital characters are in accord with some groups of the subgenus Parena. In P. taiwana, the adhesive setae occupy nearly the full length of mesotarsomere 1, whereas in subgenus Parena, the adhesive setae at most occupy slightly more than the apical half of mesotarsomere 1. Based on many other important characters mentioned above, we assigned P. taiwana into the subgenus Bothynoptera and considered that it is not closely related to species of subgenus Parena. Although P. taiwana is very similar to the P. tripunctata group in external features and female ovipositor, we consider P. taiwana to be relatively isolated in the subgenus because of its atypical male genitalia and the pattern of tarsal adhesive setae.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

038776236279FFA22DEFB2ECFF075C1B.taxon	discussion	Remarks. Parena formosana Ohkura is a primary homonym of Parena formosana Jedlička, although the latter species belongs to the genus Paraphaea now (Shi et al., 2013). A replacement name was proposed by Hua (2002) in the List of Chinese Insects. However, this literature was ignored by recent catalogues (Lorenz, 2005; L ̂ bl & L ̂ bl, 2017).	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

038776236207FFA12DEFB3F3FA7B5EC9.taxon	description	This species group contains eight species distributed mainly in East Asia. They are characterized by: body smallsized, length 6.4 – 9.1 mm; retinacular ridge of right mandible about one-third length of terebral ridge (Fig. 2 E); mentum with a pair of long setae, longer than terminal labial palpomere; elytra with distinct pattern in most species; antennae extended slightly beyond elytra base; tempora short, abruptly narrowed behind eyes, length of tempora plus neck-constriction approximately one-third of diameter of eye; elytral intervals slightly convex, very sparsely punctate; interval 3 with three setigerous pores; elytral apices evenly rounded, sutural angles indistinct; males without adhesive setae on mesotarsomere 1; abdominal sternite VII with two pairs of setae in both sexes; median lobe of aedeagus very stout (AL / AW 3.3 – 4.0); gonocoxite II of ovipositor nearly rectangular or rounded-rectangular, apex with five to seven ensiform setae, nearly evenly arranged. The endophallus in this group is very similar among different species: primary sclerite with very wide flared basal expansion, its right-basal angle strongly pointed; flagellum short, ending before the middle of median lobe; apical sclerite widely V-shaped, well-defined, basal core distinct, large, ovate, heavily chitinized and scaled; basal sheath reduced to a triangular scaled structure left-ventral to flagellum; apical sheath large and coarsely scaled; squamate sac divided or undivided, near the middle of median lobe, right to squamate sheath. The species of this group are easily differentiated by their elytra pattern (see the key above), but it is difficult to find other differences on the external features besides the color. Their stout male genitalial shaft and endophallus are also similar in all the species. Although the shape of the apical lamella varies slightly individually in some species, differences in the apex and ventral margin of aedeagus can well define each species (except for P. emarginata sp. n. with male unknown). To interpret these differences better, we provide an alternate key for the male genitalia of this group.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

Bothynoptera tripunctata Bates: This species was originally described from an unspecified number of specimens from " Tanga " and " Kawachi ". In the collection of MNHN, one male specimen from Bates's collection is perfectly in accord with the original description. We herein designate it as the lectotype (Fig. 38 A). There are three other specimens in NHML from the collection of G. Lewis without a detailed locality label that may belong to the type series as well. Crossoglossa piceola Chaudoir: This species was originally described from two specimens from " Amour ", perfectly in accord with our examined two syntypes in MNHN. We herein designate the male as lectotype (Fig. 38 B). This species was synonymized with P. tripunctata by Lafer (1989). After examining the types of both species, we found that they are only subtly different in the apical lamella of male genitalia (slightly narrower in P. tripunctata), and the synonymy is confirmed.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

038776236203FFA42DEFB367FC055C8B.taxon	discussion	Notes on types and synonyms. Parena shapingensis Xie & Yu: The holotype of this species is briefly labeled as " Shaping, 27. IX. 1943 " in handwritten Chinese without other explanation of this locality. In the original description, the type locality was explained as Guangdong (Shaping), referring to Shaping town of Heshan city. However, this speculation could be wrong because Guangdong is far from all other known localities of this species. The handwriting of the locality label is identified that of a famous Chinese entomologist, Prof. Sicien Chen. He worked in Academia Sinica in Chongqing from 1939 to 1946. Thus the type locality " Shaping " is very likely to refer to Shapingba (N 29 ° 32 ' E 106 ° 27 ') in Chongqing City. Parena yunnana Kirschenhofer: We did not examine the type of this species, but the specimens from very close to its type locality that we examined are perfectly in accord with the original description and illustration of P. yunnana. So, we confirmed that P. yunnana is identical to P. shapingensis in external and male genital characters.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

038776236201FFAB2DEFB059FA6E596F.taxon	discussion	Notes on types and synonyms. Crossoglossa monostigma Bates: Several specimens were mentioned from " Hiogo " and " Nagasaki " in the original description. In the collection of MNHN and NHML, we found four specimens in accord with the original description. We designate the only male of them as lectotype herein, although another female bears Bates's determining label. We examined two additional specimens of this species in NHML labeled as " cotype ". However, they do not belong to the type series, because their locality " Miyanoshita " is not listed in the original decription. Bates described this species as having five pores on elytral interval 3; however, we found that all examined type series have only three pores, which are consistent with most species in the genus. Parena japoincia Jedlička: This species was erected based on the different number of pores on the elytral interval 3 compared with P. monostigma. Habu firstly designated it as a synonym of P. monostigma and pointed out that the number of discal pores noted in original description of P. monostigma is incorrect. We agree with this synonymy based on our examined the types of both species. Parena koreana Kirschenhofer: The original description (Kirschenhofer, 1994) noted that P. koreana is different from P. monostigma in having the elytral black patch occupying the inner five intervals (versus three intervals). However, we found that the holotype of P. koreana has the black patch only four intervals wide. This state should be considered as individual variation and occurs in some specimens from Japan as well. Therefore, we herein synonymize P. koreana with P. monostigma.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

Laos without comparison with the very similar species P. quadrisignata. We examined the types of the two species and found that they are slightly different in the following three aspects: the background color of P. phongsalyensis is much darker; the humeral patches smaller and slightly distant from elytra base, and the subapical patches have the oblique extension very narrow and almost invisible. We cannot compare their male genitalia because the types of P. quadrisignata are females. Instead, we examined several specimens from west Yunnan, which geographically intermediate and present intermediate states of these above characters (Fig. 43 F). These specimens are almost identical to the holotype of P. phongsalyensis in male genitalia (Fig. 45). Thus, we treat P. phongsalyensis as a junior synonym of P. quadrisignata.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

03877623620AFFAE2DEFB2ECFBAC5E4F.taxon	diagnosis	Comparisons. This species is easily distinguished from all other species of subgenus Bothynoptera by dorsum dark brown with black patches on elytra. It is also distinctly larger than all other species of the P. tripunctata group. The male genitalia of this species are very similar to those of P. tripunctata, but the apical lamella is rounded-triangular and not bent toward the dorsum. In P. tripunctata, the apical lamella is rounded-truncate and weakly bent toward the dorsum.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

03877623620BFFAD2DEFB11DFE625A76.taxon	diagnosis	Diagnostic characters. Dorsum pale yellow, pronotum with a pair of dark stripes, elytra with a pair of short basal stripes and a pair of well separate subapical spots; labrum slightly dilated to apex, apex strongly emarginate; antennae extended only slightly beyond elytral base; elytra intervals with very sparse fine punctures. Comparisons. The new species is different from all other species of the genus Parena by the apex of labrum strongly emarginate (Fig. 46 C). Several other species of the P. tripunctata group have the labrum apex very weakly emarginate, but the labrum apex is straight or slightly curved in all other species groups of the genus. The elytral color pattern of the new species is similar to some individuals of P. taiwana with four spots. However, the new species can be easily distinguished from P. taiwana by: labrum apex emarginate; pronotum with a pair of dark stripes; elytral intervals without dense punctures; and antennae shorter, extended beyond the elytra base by the length of only one antennomere.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

038776236209FFB22DEFB2ECFF055C3F.taxon	diagnosis	Diagnostic characters. Dorsum reddish yellow, elytra with four black spots: a pair of basal spots distant from elytra base, not covering first discal pore; a pair of subapical spots adjacent to interval 1, each of them large and oblique-rounded, divergent from each other toward the elytral base, interval 1 yellow between the two subapical spots; labrum apex straight; median lobe of aedeagus well narrowed at apex, apical lamella narrow and long, LL subequal to LW. Comparisons. The new species is distinguished in subgenus Bothynoptera by its unique elytra pattern. It is most similar to another new species, P. triguttata sp. n., which may be sympatric with it. These two new species differ as follows: (1) in P. gonggaica, the dorsal background color is dark reddish yellow, but in P. trigutata, it is vivid reddish yellow, slightly brighter than P. gonggaica sp. n.; (2) in P. gonggaica, the elytra basal spots are more distant from elytra base, not covering first discal pore on interval 3, but in P. trigutata, the basal spots cover the first discal pore; (3) in P. gonggaica, the elytra subapical patch (composed of two nearly adjacent spots) is concave at the anterior margin, and the interval 1 is yellow between the patches, but in P. trigutata, the subapical patch is extended anteriorly at its anterior margin, and the first interval is black inside the patch; and (4) in P. gonggaica, the median lobe of the aedeagus is more narrowed toward the apex and apical lamella is longer, LL equal to LW, whereas in P. trigutata, the apical lamella is shorter, LW much greater than LL. There are other two species (P. taiwana and P. emarginata sp. n.) that also have four black patches on the elytra, but in these species the subapical spots are well separated, not adjacent to the middle.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

038776236214FFB72DEFB7D7FA7B5F12.taxon	description	The subgenus Parena s. str. includes twenty-three species, defined by the combination of the following characters: pronotum moderately transverse; mandibles strongly widened, semicircular; mentum with a pair of setae, very short in some species, lateral lobes narrow and short, apex slightly extending beyond epilobes, inner margins strongly oblique; accessory setae on antennomeres 1 and 2 absent or very short; elytral first pore on interval 3 close to base, on level of scutellar apex; gonocoxite II of ovipositor nearly rectangular, apex with five to seven ensiform setae. However, all of the above characters are inferred to be plesiomorphic, so subgenus Parena s. str. may be paraphyletic. Moreover, because the species of this subgenus are morphologically similar, treatment of these species as a subgenus is at least convenient for recognition in classification. Subgenus Parena has the widest distributional range of the three subgenera. Thirteen species have Oriental-Australian distributions, with ten species confined to the Oriental Realm (some of them can reach to the south part of Palaearctic Realm), two to the Australian Realm, and one to both realms. Some of these species are very widely distributed in the Oriental Realm (e. g., P. fasciata), while others are restricted to certain islands (e. g., P. andrewesi). Ten species occur in the African Realm, with two of them endemic to Madagascar and the other eight to the Sub-Saharan African mainland. In the present work, we revise the subgenus Parena with African and Oriental-Australian species separately, for the purpose of providing a taxonomy system easier for species determination. Otherwise, some species groups might be difficult to define. Three Oriental-Australian species groups and three African species groups are recognized, based mainly on the presence or absence of the suborbital setae and male genital characters, including the shape of the median lobe and the copulatory piece of the endophallus.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

Dorsal surface reddish brown to piceous; elytra entirely reddish brown, with dark patch or lateral stripes, or entirely metallic green or bluish green. Tempora short, abruptly narrowed behind eyes, length of tempora plus neck-constriction approximately one-third of diameter of eye; antennomeres 1 – 3 with sparse very short accessory setae in most species; postgenae with or without suborbital setae; mandibles extremely widened, semicircular, retinacular ridge of right mandible reduced to retinacular tooth (Fig. 2 B); mentum with a pair of setae, very short in some species; lateral lobes short and wide, apically rounded, inner margins strongly oblique, outer margins slightly arcuate, epilobes relatively wide, apices not extending beyond lateral lobes. Pronotum moderately wide, PW / PL = 1.26 – 1.56, slightly wider than head in most species, PW / HW = 0.92 – 1.13; lateral explanations wide; lateral margins usually more or less sinuate before posterior angles; posterior angles usually forming rounded angles. Elytral interval 3 with three setigerous pores, first pore close to elytra base, on level of scutellar apex; disc not, weakly, or strongly depressed near middle of interval 5, lateral sides slightly depressed near anterior third. Abdominal sternite VII often with two setae on each side, apex straight in females, usually more or less emarginate in males. Male mesotarsomere 1 usually with biseriate adhesive setae restricted on apical half (but without setae in five species), mesotarsomeres 2 and 3 usually with well-developed adhesive setae.

038776236212FFB72DEFB0E1FC6A5EA2.taxon	description	This species group contains three species, distributed through nearly all of the Oriental Realm and part of the Australian Realm. The two metallic species are very close to each other and are allopatric in geographical distribution. The third species is widely distributed and highly varied in elytra color pattern. Despite the different appearances, similarity in characters of the endophallic copulatory piece suggest a close relationship of these three species. Members of this species group differ from all other Oriental-Australian species in two aspects: (1) postgenae with a pair of suborbital setae; and (2) primary sclerite of endophallus linear, without a distinctly flared basal expansion (Figs 51, 52, 54). This group is most similar to the P. stigmatica group from Africa, but in the latter the basal expansion of the primary sclerite of endophallus is distinctly flared.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

038776236213FFBB2DEFB2ECFBCB5C1B.taxon	distribution	Distribution (Map 9, red). Java, Sumatra, Sulawesi, The Philippines. This species was recorded from China (Anhui) by Xie & Yu (1993). After examining the specimen, we found that their record was based on a misidentified specimen of P. monticola. Geographical variation. This species is known from four regions of the Malay Archipelago. Specimens from different localities are different in the following aspects. (1) Elytra color. Elytra are generally metallic green (Fig. 50 A) but slightly different in some specimens. For all examined specimens from the Philippines and a few from Sumatra, the elytra are bluish green (Fig. 50 C); for some other specimens from Sumatra, the elytra have bright copperish lustre near the apices (Fig. 50 B), giving them an appearance very similar to P. pendleburyi. (2) Color of venter, including mesothorax, metathorax, abdomen, epipleura, and metatibiae. These parts are always in the same color in any one specimen. They are piceous in specimens from Java and Sumatra (Fig. 50 B), and red in those from Sulawesi and the Philippines (Fig. 50 C). (3) Color of antennae. In most specimens, the antennae are completely reddish brown or apical the seven antennomeres slightly darker (Fig. 50 B). However, for the two examined specimens from the Philippines, antennae are distinctly bicolor with the basal four antennomeres reddish brown and apical seven black (Fig. 50 C). (4) Elytra microsculpture. The elytra are without or with very faint isodiametric microsculpture in specimens from most localities, but distinctly present in one female from Makassar examined.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

Phloeodromus hastatus Heller: The original description did not indicate how many types there are, but a serial number " 7243 " implied a single holotype, which is in accord with our examined specimen. For other names treated here, all holotypes were original clearly fixed by monotypy. All examined type materials of the above synonyms are very similar to each other except for the different patterns on their elytra. We studied specimens with different elytra pattern forms from various localities. Their identical male genitalia (Figs 54, 55) suggest that they all belong to the same species. So, we herein treat Phloeodromus sellatus Heller, Phloeodromus hastatus Heller, Crossoglossa sellatoides Jedlička, Parena fasciata var. unicolor Louwerens, and Parena sumatrana Kirschenhofer all as junior synonyms of Crossoglossa fasciata Chaudoir.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

03877623621FFFBE2DEFB48CFE925AD0.taxon	diagnosis	Comparisons. This species can be distinguished from all other Oriental-Australian species in subgenus Parena by the combination of the following two characters: (1) elytra yellow, with or without black patch; (2) postgenae with a pair of suborbital setae. The " unicolor " form of P. fasciata (Figs 53 E, 53 F) is similar to some other uniformly brown species, especially those African species of the P. stigmatica group, which also have the suborbital setae. P. fasciata is different from these African species in having the antennae completely yellow, versus apical seven antennomeres black. We provide a key for all uniformly yellowish brown species belonging to the subgenus Parena at the end of this paper. In P. fasciata, the rhombic form (Fig. 53 H) is somewhat similar to P. monostigma, but differs in having elytra patch wider, extended laterally at least to interval 5, and the different position of first elytral discal pore. The melanic form (Fig. 53 G) is similar to the dark form of P. africana, but differs in having suborbital setae and the elytra disc without depression.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

03877623621FFFBE2DEFB48CFE925AD0.taxon	description	Description. Body length 6.7 – 8.9 mm. Dorsum reddish yellow to yellowish brown, elytra with varied black patch, a single large patch behind middle in most specimens, without a black patch in some specimens; antennae, legs, and venter yellow. Postgenae with a pair of suborbital setae; antennae extended to elytral base; labrum quadrate, apex straight or very weakly concave; mentum with a pair of short median setae. Pronotum nearly cordate, PW / PL = 1.34 – 1.47, wider than head, PW / HW = 1.08 – 1.15; widest at anterior third, slightly rounded at anterior half, more or less sinuate before posterior angles; posterior angles widely obtuse.

Australia, Papua New Guinea, Sulawesi, Maluku, Timor, Java, Sumatra, the Philippines, Vietnam, Thailand, China (Taiwan, Hainan, Zhejiang). Variation. P. fasciata is widely distributed through Southeast Asia and the north part of Australasia. Its elytra color is highly varied, as might be expected with such a distribution. Generally, the following seven color forms can be recognized, but with intermediate specimens also seen. In the citations of examined materials above, we recorded the color form of each specimen by abbreviation in brackets. (1) The " fasciata " form [f] (Fig. 53 A): elytra with a transverse black patch. Type of P. fasciata belongs to this form. Most specimens from regions eastern to the Wallace’s line are of the typical " fasciata " form, which has a very large black patch near elytral mid-length. A few specimens from Java and the Philippines also have the " fasciata " form, but the patch is usually shorter than in typical specimens. (2) The " sellata " form [s] (Figs 53 B, 53 D): elytra with a triangular black patch. Types of P. sellata, P. sellatoides and P. sumatrana all have this form. It is the most common form in regions west of Wallace’s line, but not found in regions east of that line. (3) The " unicolor " form [u] (Figs 53 E, 53 F): elytra unicolorous, without a black patch. Type of P. unicolor belongs to this form. The " unicolor " form occurs in Java and Timor, and is relatively common in Javan populations. (4) The rhombic form [r] (Fig. 53 H): elytra with a narrow rhombic black patch. This form occurs in Vietnam, the Philippines and Java at a low frequency. (5) The " hastata " form [h] (Fig. 53 C): elytra black patch with anterior margin notched. Type of P. hastata has this form. The " hastata " form occurs in Java and the Philippines at a low frequency. (6) The melanic form [m] (Fig. 53 G): elytral black patch very large, with only a narrow apical region brown. This form was found in only one specimen from Papua New Guinea and is very similar to another species, P. africana. (7) The trident form [t] (Fig. 53 I): elytra with trident black patch. This form was found in only one specimen from the Philippines.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

038776236218FFBC2DEFB4CCFAA85805.taxon	description	This species group contains six species distributed through nearly all the Oriental Realm and part of the Australian Realm. This group is characterized in the Oriental-Australian species of subgenus Parena as follows: postgenae without suborbital setae; elytra not metallic; male mesotarsomere 1 with or without adhesive setae ventrally; male genitalia with apical lamella thin, apex bent dorsally in lateral view; endophallus with distinct flared basal expansion of primary sclerite; gonocoxite II of ovipositor slightly pointed near apical inner angle, ensiform setae grouped near apical angles. This species group is very similar to the P. plagiata group from Africa, even in the characters on male and female genitalia, so they may be very closely related. Four species of this group are very similar externally, except for differences in coloration. The other two species P. andrewesi and P. politissima, are quite different from the other four in having elytra with deep depressions and very shallow striae. Moreover, P. andrewesi is also different from other species of this group in having male abdominal sternite VII more deeply emarginate and gonocoxite II of ovipositor longer than in other species.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

038776236219FF802DEFB7DCFC765AD7.taxon	discussion	Notes on types and synonyms. Plochionus nigrolineata Chaudoir: This species was described from an unspecified number of specimens from " nord de l'Hindostan " presented by Captain Boys. We examined three specimens in Chaudoir's collection in MNHN. Only one of them is in accord with the original description. We designate this male as lectotype herein. The other two specimens, not belonging to the type series, could be subsequently added to Chaudoir's collection. One of them, a female labeled as " lateralis m., in India Orient " is the type of a nomen nudum, Plochionus lateralis Dejean, 1836: 11. Parena nigrolineata nipponensis Habu: This subspecies was erected based on having its elytra stripes much wider than the nominotypical subspecies from India. We studied specimens from different localities and confirmed that all specimens from Japan have wider elytra stripes than those from India. However, their male genitalia are almost identical, and the width of stripes is quite varied in some other localities (e. g. China). Thus, the width of elytra stripes cannot be used to define subspecies within P. nigrolineata. So we herein treat Parena nigrolineata nipponensis Habu as a junior synonym of Plochionus nigrolineata Chaudoir. Parena schillhammeri Kirschenhofer: This species was described from Sulawesi and differs from P. nigrolineata only in having the elytra lateral stripes very wide, extended medially to stria 3 at the middle of elytra. All specimens from Sulawesi examined have this form of elytra pattern. We studied the holotype and found that its male genitalia are identical to those of P. nigrolineata except for having the right margin of the median lobe slightly sinuate before the apex. Considering that P. nigrolineata is a widely distributed and varied species, we treat Parena schillhammeri Kirschenhofer as a junior synonym of Plochionus nigrolineata Chaudoir herein. Crossoglossa latecincta Bates: The syntypes of Bates's species belong to two species. Based on the examination of some of syntypes, Crossoglossa latecincta Bates was erroneously synonymized with Plochionus nigrolineata Chaudoir by authors (Andrewes, 1921; Jedlička, 1963). Detailed discussions on these two species are provided under P. latecincta.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

This species can be distinguished from all other Oriental-Australian species in subgenus Parena by a combination of the following three characters: (1) elytra with black lateral stripes in most specimens, without metallic lustre; (2) all legs reddish brown; (3) median lobe of aedeagus slender (AL / AW = 5.3 – 6.0), apex slightly bent upwards. We examined one male of P. nigrolineata from China (Shanghai) without elytra stripes (Fig. 56 D), which is very similar to P. picea from Australia. It can be distinguished from the latter species by dorsal color lighter, apical lamella of aedeagus narrower, and a different distribution. We examined one female of P. nigrolineata from China (Guizhou) with elytra stripes ended much before the elytral apices (Fig. 56 E), which is very similar to P. amamiooshimensis from the Ryukyu Islands. It can be distinguished from the latter species by elytral background color lighter and a different distribution.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

Geographical Variation. The elytra black stripes of this species vary geographically. In most specimens from East Asia, the lateral black stripes are extended medially to interval 5 or 6 in the middle (Fig. 56 F). In specimens from Sulawesi, elytra have the widest lateral black stripes reaching the fourth interval in the middle (Fig. 56 B). Specimens from India have the narrowest lateral black stripes extended only to interval 7 in the middle (Fig. 56 A). However, the elytral stripes are sometimes varied among specimens from same locality. For example, in some specimens from China examined, the elytra stripes extend medially interval 7 only (Fig. 56 E) or are absent (Fig. 56 D). The apex of the aedeagus also varies slightly in this species in two aspects: the shape of the apical lamella and the degree of sinuation of the right margin before the apex (Figs 57, 58). However, these variations are subtle and continuous and do not support a subspecific division of this species.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

038776236222FF852DEFB2ECFAD35EDB.taxon	diagnosis	Comparisons. This species can be distinguished from all other Oriental-Australian species in subgenus Parena by a combination of the following two characters: (1) dorsum completely dark reddish brown; (2) postgenae without suborbital setae. P. picea is similar in general appearance to individuals of P. fasciata without an elytra patch but differs in having postgenae without suborbital setae and the dorsum generally much darker. P. picea is also similar to some unicolorous species in the P. plagiata group from Africa, but differs in having the dorsum darker in color, elytral striae more deeply incised, and dark apical antennomeres less contrasting with the basal yellow antennomeres. P. picea could be very close to P. nigrolineata. Their male genitalia are very similar to each, even for the apical lamella, with the contour and length-width ratio almost identical. The main difference between their male genitalia is that the median lobe of aedeagus is a little thicker in P. picea, with the AL / AW = 4.7 – 5.0 (versus AL / AW = 5.3 – 5.9 in P. nigrolineata). In addition, these two species also have small differences in the endophallus, mainly in the length of the flagellum, width of apical sclerite, and size of squamate sacs.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

Externally, P. amamiooshimensis differs from P. nigrolineata mainly in having the elytra black stripes obliterated from the apices and background color darker. According to Habu (1967), these differences are valid when determining Japanese species. However, we examined one specimen of P. nigrolineata from Guizhou, China (Fig. 56 E) having elytral stripes similar to P. amamiooshimensis, and two specimens of P. nigrolineata from Yunnan having dark reddish brown background similar to P. amamiooshimensis. Thus, distributional information is sometimes necessary when identifying this species.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

038776236221FF8A2DEFB6CBFBF2596F.taxon	diagnosis	Diagnostic characters. Dorsum reddish brown, elytra with black lateral stripes, without metallic lustre, elytra lateral margins black; legs with apical third of femora and entire tibiae black; postgenae without suborbital setae; median lobe of aedeagus stout, right margin weakly sinuate before apex, apical lamella narrow, LL 1.5 times LW, apex slightly bent dorsally. Comparisons. P. picipes sp. n. is distinguishable by its black tibiae among all Parena species with elytral lateral stripes. It is most similar to P. nigrolineata and P. amamiooshimensis, but different in the black color of tibiae, femoral apices, and elytra lateral margins. The new species also has the male genitalia very different from the other two species. Compared to P. nigrolineata, the new species is different in the median lobe stouter (AL / AW 4.4 – 4.6, versus 5.3 – 6.0 in P. nigrolineata) and apical lamella much narrower (LL 1.5 times LW, versus LL slightly greater than LW in P. nigrolineata). Compared to P. amamiooshimensis, the new species is different in median lobe less stout and apical lamella much narrower.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

It could be close to P. politissima for the similarities in their external features and male genitalia. These two species are different from others in the P. nigrolineata group by: elytra striae barely incised, elytra disc distinctly depressed near basal third. P. andrewesi is also different from the other species of this species group in: apex of abdominal sternite VII well emarginate in males; gonocoxite II of ovipositor more elongate.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

03877623622DFF8F2DEFB1F1FEB65A7F.taxon	discussion	Remarks. This species is only known by four specimens collected from three Pacific Islands. However, the three ones from Samoa and Vanuatu (Fig. 62 F) are somewhat different from the holotype (Fig. 62 E) in: (1) size much smaller, Body length = 7.3 – 8.3 mm (10.1 mm for the holotype); (2) dorsal color lighter, dark reddish brown (pitchy for the holotype); (3) pronotum much narrower, PW / PL = 1.30 – 1.39 (PW / PL = 1.55 for the holotype). These three specimens were determined as P. politissima by Andrewes (1927 b). We follow his treatment and consider the above differences as geographical variation, whereas the males from the type locality are necessary for future studies to prove this.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

03877623622BFF912DEFB71EFBA25E4F.taxon	discussion	Notes on types and synonyms. Crossoglossa latecincta Bates: The original description did not indicate how many specimens were in the type series but mentioned three type localities: " Hiogo ", " Yokohama " and " Hong Kong ". In the collection of MNHN, we found two specimens that used to be in Bates's collection in accord with the type localities. However, they belong to different species: the first one (male from Yokohama, Fig. 56 C) is P. nigrolineta and the second one (female from Hiogo, Fig. 66 A) accords with P. latecincta sensu Habu (1967) and P. viridilineata Jedlička. Bates's brief original description accords with both species. Because Habu (1967) provided an ample description and illustrations for P. latecincta, and his concept was followed by several essential literature (e. g., Kryzhanovskij et al. 1995, L ̂ bl & Smetana, 2003), we herein designate the female from Hiogo as lectotype of Crossoglossa latecincta Bates for the purpose of taxonomical stability. Hereafter, P. latecincta (Bates) is fixed as a valid species name, and P. viridilineata Jedlička as its junior synonym. There are two other specimens in the collection of MNHN also labeled as type of this species: the first from the Bates collection labeled " Kiu-Kiang " and the second from the Chaudoir collection labeled " Japan, G. Lewis ". They are not in accord with the original description and do not belong to the type series. In the collection of NHML, we examined three specimens labeled as type of Crossoglossa latecincta, all from G. Lewis's collection and not in accord with the type localities. Thus, they also are not part of the type series .. The above five " types " are all identical to P. nigrolineata. Several authors (Andrewes, 1921; Jedlička, 1963; Kirschenhofer, 2006) treated P. latecincta as junior synonym of P. nigrolineata. Their decisions might all be based on these " false " types of P. latecincta in the collection of NHML.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

In P. circumdata, the large central brown area of the elytra has a strong metallic purple hue and narrower green lateral stripes, which extend only to interval 7 at middle. Individuals of C. latecincta with very wide green stripes maybe somewhat similar to P. rubripicta, but can be distinguished from the latter species by the absence of suborbital setae. This species also might be confused with P. nigrolineata, but the elytral lateral stripes have no trace of metallic green in the latter species. We examined one very atypical male specimen of P. latecincta from Taiwan with completely black elytra stripes; but this specimen is different from P. nigrolineata in having the vertex more densely punctate, pronotum more strongly constricted toward the base, male mesotarsomere 1 without adhesive setae, and very different male genitalia.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

Korea, Russia (Primorye), China (Liaoning, Beijing, Shaanxi, Henan, Shandong, Anhui, Zhejiang, Hunan, Fujian, Sichuan, Chongqing, Guizhou, Yunnan, Taiwan, Hong Kong), Vietnam (Tonkin), Laos, Thailand, India (Darjeeling), Nepal, the Philippines (Mindanao, Negros). Geographical variation. The external features of this species vary slightly geographically, mainly in the elytra color pattern. Specimens from most parts of China (except for Yunnan) and Japan have the elytral lateral stripes well separated at the base, only extended medially to intervals 4 or 5 (Fig. 66 C). In contrast, most specimens from India, Yunnan and Indochina have the lateral stripes continuous at the base or, in a few specimens, slightly separated (Figs 66 D, 66 E). The four examined specimens from the Philippines have an elytra pattern very different from the others: the lateral stripes are cyanic green in color and in sharp contrast with reddish brown disc; the green stripes are widely continuous basally, inner intervals with basal fourth completely green; epipleura and elytra lateral margins metallic green (Fig. 66 F). However, one other male from the Philippines has the elytra pattern almost the same as other specimens from Indochina, and its genitalia are the same as the other males with wide lateral stripes. Thus, we conclude that these individuals from the Philippines with the atypical elytra pattern represent only a local form. In addition, most specimens from western Yunnan, Indochina, India, and Nepal have a darker color (very dark brown) on the head and pronotum. Most specimens from China and Japan have the antennae completely reddish brown, compared with these from other localities, which have the apical antennomeres more or less darkened. The male genitalia of this species vary only slightly among different localities, mainly in the shape of the apex of the median lobe. In specimens from Japan, Taiwan, and northern China, the apical lamella is very wide in dorsal view, LL much smaller than LW, slightly declined to the left and the right margin of the shaft is gradually sinuate before apex in dorsal view (Fig. 67 B). In specimens from most parts of southern China, the apical lamella is narrower in dorsal view, LL equal to LW, slightly declined to left; and the right margin of the shaft is gradually sinuate before apex in dorsal view (Fig. 67 A). In specimens from western Yunnan, Indochina and India, the apical lamella is straight, not declined to the left, and the right margin of the shaft has an abrupt small angle before the apex in dorsal view (Figs 68 A, 68 B). In specimens from the Philippines, the apical lamella is straight, not declined to the left, and the right margin of the shaft is straight, without angle or sinuation before apex in dorsal view (Fig. 68 C). The differences in male genitalia between localities seem to be stable, but we tend to treat them all as one species without division into subspecies because there are no stable external differences between them, and the present treatment as one species is corresponding to that in other widely distributed species of the genus.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

This species differs from other species of the genus by the combination of: elytra entirely metallic green, postgenae without suborbital setae, and males with adhesive setae on mesotarsomere 1. Compared with other species in this group, P. monticola is most similar to P. pendleburyi in having elytra without lateral stripes and microsculpture. However, P. monticola is different in having elytra without reddish copper lustre on elytral humeri and subapices, elytral striae deeper, elytra discal depressions deeper, venter lighter in color, and apical lamella of aedeagus narrower. This species is also similar to P. bicolor in having elytra entirely metallic green. However, P. monticola is slightly larger in body size, most specimens have the elytra with a slightly copperish hue, and, most importantly, the postgenae lack suborbital setae.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

03877623623EFF9B2DEFB2ECFD915FFE.taxon	description	This species group contains three allopatric species from Africa. Each of them was known from only a few specimens and narrow distributional ranges. This group is readily distinguished from other African species by the presence of suborbital setae. Compared with the P. fasciata group from the Oriental Realm, another species group of subgenus Parena with suborbital setae present, the P. stigmatica group differs in its male genitalia, with a large, flared expansion of the primary sclerite of the endophallus. All three of these species in P. stigmatica group are uniformly yellowish brown to dark brown, but they are distinguished from each by the differences on the color of antennae, the elytral discal depression, pronotal shape, and depth of the elytral striae. Although the presence of suborbital setae unites this African species group, the shape of male genitalia suggests otherwise. The two species of this group for which male are known differ significantly in the shape of aedeagus. P. fulva sp. n. has a very stout median lobe with thick apical lamella which is unique among African Parena, and P. stigmatica has a slender median lobe with dorsally bent apical lamella, which is somewhat similar to the other Madagascan species, P. madagascariensis.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

Dorsum yellowish brown, elytra without pattern; antennae with basal three antennomeres yellow, apical half of fourth and remaining tarsomeres black; tarsi black; postgenae with a pair of suborbital setae; pronotum with lateral margins nearly straight before posterior angles; elytra discal depression indistinct; median lobe of aedeagus very stout; apical lamella thick and coniform. Comparisons. P. fulva sp. n. is different from most African species in having suborbital setae. Compared with the two other African species with suborbital setae, the new species can be readily distinguished in having the dorsum with paler color, antennae distinctly bicolored, elytra without discal depressions, and pronotum with lateral margins nearly straight before posterior angles. From the original labels, we found that several specimens of this new species were misidentified as P. ferruginea. However, P. fulva sp. n. is different from the latter species in having suborbital setae present and the pronotum wider and with lateral margins only faintly sinuate before posterior angles. In several important features, the " unicolor " form of P. fasciata distributed in the Oriental Realm is most similar to P. fulva sp. n., but the Oriental species differs in having antennae uniformly yellow and male genitalia much slenderer. The new species also differs from all other African species in having its male genitalia very stout (AL / AW = 3.7 – 3.9), resembling some species from the Oriental realm, such as P. latecincta.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

03877623623BFF9D2DEFB44EFE685CAF.taxon	description	This species group contains three species distributed in the Sub-Saharan African mainland and one species from Madagascar. This group is characterized by: postgenae without suborbital setae; elytra not metallic, uniformly reddish brown or with dark patches; elytral apices distinctly truncate, apical margin nearly straight, sutural angles more or less pointed, very faintly so in some species; elytra with or without microsculpture; antennomere 1 with the ventroapical seta only slightly shorter than the dorsoapical one; male genitalia with LL greater than LW, apex slightly bent dorsally; gonocoxite II of ovipositor quadrate, apex more or less emarginate. This species group is most similar to the P. plagiata group in having postgenae without suborbital setae and a similar elytra color pattern (four species of these two groups have their elytra largely dark with a narrow red apical band). Although members of these two groups have similar external appearances, we divided them into different species groups based on differences in the following important aspects: shape of elytral apices, length of the apical setae of antennomere 1, and shape of the male genitalia and female ovipositor. Species of the P. scutata group have distinctly truncate elytral apices with the sutural angles more or less pointed, although very faint so in some species (Figs 5 B, 5 C, 5 D). This character state is unique in the subgenus Parena, but presents in several species of the subgenus Crossoglossa. Moreover, in the P. scutata group, the ventroapical seta of antennomere 1 is only slightly shorter than the dorsoapical one (Fig. 1 D), whereas, in all other species of this genus, the ventroapical seta is less than half the length of the dorsal-apical one (Figs 1 A, 1 B, 1 C). In all studied species, the male genitalia and female ovipositor also have significant differences between these two groups. In the P. scutata group, the median lobe of aedeagus is slenderer and the apical lamella is much longer than in the P. plagiata group. In the P. scutata group, gonocoxite II of the ovipositor is nearly quadrate with its inner and outer margins equally in length, whereas in the P. plagiata group, gonocoxite II is strongly pointed near its inner apical angle with its inner margin much longer than the outer margin.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

Crossoglossa madagascariensis Alluaud: The original description mentioned three specimens from " Montagne d'Ambre ", but no holotype was fixed. In the collection of MNHN, we found two males perfectly in accord with the original description. We herein designated the one with Alluaud's handwriting label as the lectotype. Parena alluaudi Jeannel: The original description mentioned one female from " Mahatsinjo ". In the collection of MNHN we found one specimen perfectly in accord with the original description, but the holotype is a male. This specimen is very similar to the type of P. madagascariensis, except the color is slightly lighter. After examining the male genitalia of the holotype of P. alluaudi, we found that it is perfectly identical with P. madagascariensis (Figs 77, 78). Thus, we treat Parena alluaudi Jeannel as a junior synonym of Crossoglossa madagascariensis Alluaud herein.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

038776236239FF622DEFB2ECFBB45C8B.taxon	diagnosis	Comparisons. This species can be readily distinguished from all other species of the subgenus Parena by the shape of elytral apices, which are distinctly truncate, with outer apical angles rounded-angulate and sutural angles forming sharp spines (Fig. 5 D). For species of all other species groups in the subgenus Parena, the elytra apical margin is evenly curved with sutural angles not pointed (Fig. 5 A). In the other three species of the P. scutata species group, the elytral apical margin is only moderately truncate, with the outer apical angles nearly rounded and sutural angles forming very small denticles (Figs 5 B, 5 C). P. madagascariensis is also different from the other three species of the same species group in having elytra without a dark pattern, elytra with shallow isodiametric microsculpture, and slightly larger size. P. madagascariensis is quite distinct from all other known species in the subgenus Parena but is externally similar to an Oriental species, P. kurosai, of subgenus Bothynoptera. These two species can be distinguished by differences in the position of the first elytral discal pore.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

This species differs from other African species of Parena by the combination of: dorsum reddish brown, elytra with a pair of dark stripes gradually fading toward apices; postgenae without suborbital setae; antennae and legs uniformly reddish brown. As indicated in the original description (Facchini, 2011), this species is similar to P. ferruginea, but differs in its unique color: elytra with dark stripes, antennae unicolor, and tarsomeres not darkened. Furthermore, we found one more difference between these two species: the elytra sutural angles are slightly pointed, forming short denticles in P. valeriae, but indistinct in P. ferruginea. We considered this species to be closest to P. madagascariensis based on having the elytral apex truncate, sutural angles pointed; antennae completely brown, and apical lamella of aedeagus elongate. Compared to the latter species, P. valeriae differs in having the elytra with black lateral stripes, elytral outer apical angles rounded (Fig. 5 C), elytral striae shallower, elytra without microsculpture, apical lamella of the aedeagus shorter, and the endophallus of male genitalia with the primary sclerite present only in the basal half.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

0387762362C4FF602DEFB623FADF5E93.taxon	diagnosis	Comparisons. P. scutata can be readily distinguished from other African species of Parena by its unique elytral color pattern: elytra largely black with well defined central red patch before middle, occupying inner four or five intervals. This species is most similar to P. africana and P. plagiata, also having their elytra are all largely black. In addition to the presence of the elytra red patch, P. scutata also differs from these other two species in having the elytral apices slightly truncate, sutural angles forming small denticles, elytra without microsculpture, and body size generally slightly larger. Similar shape of the elytral apices and absent of elytral microsculpture suggest that this species is closer to P. valeriae than to the above mentioned species, but it differs from P. valeriae in having the antennae distinctly bicolor, elytral sutural angles less pointed; and a different elytra color pattern.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

0387762362C4FF602DEFB623FADF5E93.taxon	discussion	Remarks. Basilewsky (1961) proposed the synonymy of P. scutata and P. plagiata without detailed explanation. From our study of the types of P. scutata and non-type materials of P. plagiata from South Africa, we found that these two species are quite different: (1) P. scutata has a well defined red central patch on elytra, but this patch is vague in P. plagiata; (2) the red apical margin on the elytra is much wider in P. scutata; (3) P. scutata has no microsculpture on the elytra, but isodiametric microsculpture is evident on the elytra of P. plagiata; (4) in P. scutata, the elytral apices are more distinctly truncate with sutural angles slightly denticulate, but in P. plagiata, the elytral apices are subtruncate with sutural angles not pointed. Although the male genitalia of P. scutata is unknown, these above external differences indicate that P. scutata and P. plagiata are two distinct species. Furthermore, P. scutata is considered to be closer to P. valeriae than to P. plagiata or P. africana, although the latter two species share with it similar elytra patterns, because P. scutata and P. valeriae both have truncate elytra apices, denticulate sutural angles, and elytra without microsculpture. The following species, P. ruficornis sp. n,. shows some intermediate characters between these two species (detailed discussions are provided below).	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

0387762362C5FF672DEFB66BFF175B2F.taxon	diagnosis	Diagnostic characters. Dorsum reddish brown, elytra largely black, suture and apex reddish brown; antennae uniformly reddish brown; tarsi yellow; elytra without microsculpture; elytral apices evidently truncate, outer apical angles well rounded, sutural angles slightly pointed, forming small denticles; gonocoxite II of ovipositor nearly quadrate, apex shallowly emarginate, with very long ensiform setae. Comparisons. This new species is very similar to other two African species, P. plagiata and P. africana, in elytra pattern (elytra largely dark with narrow red apices). However, the new species is quite different from them in: (1) elytra without microsculpture (with shallow isodiametric microsculpture in the other two species); (2) elytral apices distinctly truncate, apical margin straight near suture, and sutural angles slightly denticulate (Fig. 5 B) (apical margin evenly rounded, sutural angles not pointed in the latter two species, Fig. 5 A); and (3) antennomere 1 with the ventroapical seta only slightly shorter than the dorsoapical seta (Fig. 1 D) (the ventroapical seta less than half length of the dorsoapical seta in the other two species, Fig. 1 C). These three characters are considered to be important and support placing these three species in different species groups. (see discussions for P. scutata species group). The new species is sympatric with P. africana in the Central African Republic. In addition to the differences mentioned above, these two species are also different in having (1) first elytral interval completely reddish brown in P. ruficornis sp. n., but largely black in P. africana; (2) pronotum with lateral margins hardly sinuate before posterior angles in P. ruficornis sp. n., but more evidently sinuate in P. africana; and (3) in P. ruficornis sp. n., gonocoxite II of ovipositor nearly quadrate with very long ensiform setae (much longer than half of the basal width), but in P. africana, gonocoxite II of ovipositor nearly subulate (strongly pointed near inner angle) with relatively short ensiform setae (less than half of the basal width). Despite the different elytra pattern, P. ruficornis sp. n. is considered to be close to P. scutata and P. valeriae based on similarities in the shape of the elytral apices, elytra microsculpture, and setae on antennomere 1. The new species is different from P. scutata in: (1) P. scutata has seven apical antennomeres nearly black and basal ones reddish brown, but in the new species the antennae are entirely reddish brown; (2) in P. scutata, the elytral disc has a large red central patch which occupies the inner four or five intervals, but in the new species the elytra have no such red patch, instead just a narrow red stripe occupying the full length of interval 1; (3) in P. ruficornis sp. n., the elytral apices are more distinctly truncate and the sutural angles are more strongly pointed. The new species differs from P. valeriae in having slightly shallower elytra striae, smaller elytral sutural denticles, and a quite different elytra pattern. The above differences, especially for the color of antennomeres and shape of the elytral apices, are consistently useful for distinguishing different species in other groups of the genus. Therefore, we are confident that the new species is different from all related species, although the males of P. scutata and P. ruficornis sp. n. are both unknown at present.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

0387762362C2FF662DEFB4BAFF205C47.taxon	description	This species group contains three species distributed in the Sub-Saharan African mainland. This group is characterized by: postgenae without suborbital setae; elytra not metallic, uniformly reddish brown or with large dark patches; elytral apices subtruncate, apical margin evenly curved, sutural angles not pointed (Fig. 5 A); elytra with shallow isodiametric microsculpture; antennomere 1 with the ventroapical seta shorter than half length of the dorsoapical one; male genitalia with apical lamella small, LL much shorter than LW, apex slightly bent dorsally; gonocoxite II of ovipositor subulate, strongly pointed near inner apical angle. In P. africana, the most widespread and common species of this group, the elytra color pattern shows pleomorphism: some individuals have the typical dark elytra pattern while a few others are evenly yellowish brown. In other species of this group, elytral pleomorphism may occur as well, but more material from Africa is required to prove this.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

This species differs from other African Parena by the combination of dorsum uniformly reddish brown, postgenae without suborbital setae, elytral striae very shallowly incised, antennae distinctly bicolored, and tarsomeres much darker than tibiae. Among specimens that we examined in collections, two other African species with completely brown elytra were misidentified as P. ferruginea by previous experts, including P. fulva sp. n. and the pale form of P. africana. P. fulva sp. n. differs from P. ferruginea in having postgenae with suborbital setae and antennae uniformly yellow.

0387762362C3FF642DEFB7F0FE4A5FF3.taxon	discussion	Remarks. The pale form of P. africana was misidentified as P. ferruginea by Basilewsky (1955). He noticed the differences between these specimens and the type of P. ferruginea: tarsi not black but at most dark brown; eight apical antennomeres dark brown (Basilewsky, 1955). We found two more differences between them: the elytra striae in P. africana are evidently deeper, shallow but incised throughout their length, while the elytra striae are shallower and not incised on the apical half of elytra in P. ferruginea; the pronotal lateral margins in P. africana are strongly sinuate before posterior angles, but only very gently sinuate in P. ferruginea. Because the above two characters are constant in P. africana, we treat these as two distinct species for now. However, whether the above external characters can support the validity of these two species is still in doubt because the male genitalia of the typical P. ferruginea are unknown.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

P. plagiata is distinguished among the African species of Parena by its unique elytra pattern: elytra with a very narrow red apical margin, inner intervals somewhat reddish at the middle, forming a vague central patch. This species is most similar to the dark individuals of P. africana in elytra pattern and the shape of elytral apices; but it differs from the latter species in: (1) elytral red apical margin much narrower; (2) elytral discal depressions more elongated; (3) lateral margins of pronotum less sinuate before posterior angles; and (4) median lobe of aedeagus stout, much stouter than in P. africana.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

0387762362CEFF692DEFB6ACFE46589B.taxon	diagnosis	Comparisons. P. africana can be readily distinguished from other African species of Parena by the combination of elytra mainly black with brown apical margin or entirely brown; antennae distinctly bicolor; tarsi same color as tibiae; postgenae without suborbital setae; pronotum with lateral margins strongly sinuate before posterior angles; elytral sutural angles not pointed. There are two very different color forms in this species. The pale form is externally very similar to P. ferruginea, and the dark form is similar to P. plagiata and P. scutata. The differences between P. africana and those three species are provided under each of them, respectively.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

0387762362CEFF692DEFB6ACFE46589B.taxon	description	Description. Body length 7.3 – 10.4 mm. Dorsum reddish brown, moderately polished; elytra color dimorphic: entirely reddish brown (Fig. 80 D) or mainly black with narrow red apical margin, red area occupied apical tenth to eighth of elytra, disc without central red patch (Figs 80 C, 80 E, 80 F). Antennae distinctly bicolor: basal four antennomeres reddish yellow, apical ones nearly black. Scutellum reddish brown; venter reddish brown; legs uniformly reddish brown. Vertex with sparse fine punctures; postgenae without suborbital setae; mentum with a pair of median setae, which are shorter than terminal labial palpomere; antennae extended to pronotal base. Pronotum sub-cordate, PW / PL = 1.32 – 1.46, subequal width as head, PW / HW = 0.97 – 1.07; widest at anterior third, lateral margins evenly rounded before middle, strongly sinuate before posterior angles; posterior angles rounded-obtuse, not prominent; lateral explanations slightly wide; disc finely wrinkled and punctate near median line. Elytra slightly dilated to apex; with isodiametric microsculpture, usually very shallow; striae faintly incised on apical half, with rows of fine punctures; intervals faintly convex, with fine punctures; discal depressions shallow, nearly triangular, occupying intervals 3 to 6, less than one-third of elytra length; elytral apices well rounded, sutural angles not pointed. Males with biseriate adhesive setae on apical half of mesotarsomere 1 and almost full length of mesotarsomeres 2 – 3. Apex of abdominal sternite VII straight, with two setae on each side in both sexes. Median lobe of aedeagus slenderer than the previous species (AL / AW = 4.5 – 4.8), ventral margin nearly straight at middle; apical lamella slightly thick, LW slightly greater than LL, apex rounded; in lateral view, apical lamella slightly bent upward. Endophallus with very widely flared basal expansion of primary sclerite; flagellum extending almost to base of apical orifice; apical sclerite widely V-shaped, well-defined, basal core distinct, small and strongly scaled; basal sheath coarsely scaled, apical sheath finely scaled, slightly larger than basal sheath; squamate sac divided, dorsal to squamate sheath; proximal sac large and dorsal-ventrally compressed, distal sac much smaller than proximal sac, closer to apex. Gonocoxite II of ovipositor nearly quadrate, length subequal to basal width, apex concave, inner apical angle strongly pointed; with two or three ensiform setae on outer apical angle, three on inner apical angle.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).

0387762362CEFF692DEFB6ACFE46589B.taxon	discussion	Remarks. P. africana is the most common and widespread Parena species in the African continent. After studying materials with dark and pale elytra from several localities, we found that these two forms with entirely different elytra colors belong to the same species. Aside from their different elytral color, they are identical in pronotal shape, elytral apices, microsculpture, antennal color, and, most importantly, the male genitalia (Fig. 82). We examined a total of 37 specimens, nine of which were of the pale form (marked by an asterisk in the citations of examined materials) and the other 28 of the dark form. The pale form of P. africana might be confused with several other species without a distinct elytra color pattern. Within subgenus Parena, ten species have uniform elytral color, which varies from reddish yellow to dark brown. All members of seven of these have monochromatic elytra, but the other three species are pleomorphic, with only a few individuals having the yellowish-brown unicolorous form. These ten species are classified into several different species groups, but their similar external appearances make their identification troublesome. To facilitate the identification of specimens of these species, we provide a key to species in the subgenus Parena with uniformly yellowish brown elytra.	en	Shi, Hongliang, Liang, Hongbin (2023): Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina).
