            <p> Differential diagnosis. This species belongs to the genus  Benedictus as it has a distinct antebasal transverse impression and posteriorly open procoxal cavities, i.e. a combination of characters unique for  Benedictus among apterous moss and leaf litter inhabiting flea beetles in Asia.  Benedictus sagittalis sp. nov. is easily distinguishable from all other species of the genus in having a completely unique, arrow-like apex of the aedeagus (Fig. 1H). </p>
            <p>Description. Habitus (Figs 1 A–C). Body 1.7 mm long, 1.1 mm wide in maximum, oval in dorsal view, strongly convex in lateral view, 0.8 mm high in maximum. Color of all body surfaces light brown, eyes black, basal margins of pronotum and elytra somewhat darkened.</p>
            <p>Head hypognathous, triangular. Frontal calli subtriangular, distinct, but feebly projecting, nearly connected to each other. Interantennal space flat, projecting, finely chagrined. Vertex shiny, impunctate. Antennae 11-segmented. Antennomere I wide, antennomere II bulbose, antennomere III thinner and shorter than I and II. Antennomeres IV–XI gradually widening. Frontal ridge strongly projecting, wide in interantennal space and strongly narrowing below. Space on sides of frontal ridge strongly and widely depressed, depressions finely chagrined, surrounded anteriorly by longitudinal edges between antennal insertions and anterior margins of clypeus. Labrum with shallow notch in middle of anterior margin, dark brown, long, about 1.2 × as wide as long, with four long setae. Anterior margin of clypeus darker than head, clypeus with six setae (two pairs of setae laterally and one pair in the middle of clypeus).</p>
            <p>Thorax. Pronotum very convex, 1.3 × as wide as long, anterolateral and posterolateral margins of pronotum projecting, posterolateral corners of pronotum sharp, basal pronotal transverse impression deep, with row of punctures. Elytra strongly convex, with 11 well-developed rows of small punctures. Basal part of epipleura very wide, strongly narrowing to elytral apex. Legs light brown, metatibia straight, apex of metatibia pilose, metatibial spine slender and short, metatarsomere I about 0.8× as long as metatarsomeres II and III combined.Anterior coxal cavities open, intercoxal prosternal process surpassing coxae and feebly widening posteriorly.</p>
            <p>Abdomen with five visible ventrites, ventrite I nearly as long as ventrites II–V combined. Ventrite II slightly longer than III, ventrites III and IV equally long. Ventrite V as long as ventrites II and III combined.</p>
            <p>Genitalia. Aedeagus (Figs 1 H–I) long, with basal part slightly wider than apical, apex of aedeagus with distinct pointed arrow-like ending. Spermatheca (Fig. 1D) with receptacle bulbose, pump wide and long. Duct directing posteriorly, forming three round loops and then directing anteriorly. Vaginal palpi (Fig. 1G) long, slender, converging apically. Tignum simple (Fig. 1F).</p>
            <p>Etymology. The name is inferred from Latin sagitta meaning ‘arrow’, and refers to the distinctive shape of the apex of the aedeagus. Adjective.</p>
            <p> Biology. The specimens were found in pitfall traps in mountain areas. Other species of  Benedictus are considered to be leaf litter or moss-inhabiting. We cannot clearly justify  B. sagittalis is a moss-inhabitant, but it can be considered at least as a ground-living, leaf litter-inhabiting forest beetle, as it was found only in pitfall traps. </p>

            <p> Differential diagnosis. This new species belongs to the genus  Cangshanaltica based on following characters: (1) pronotal anterolateral setiferous pore placed in the middle of the pronotal side margin; and (2) antennomere VII with a distal protrusion.  Cangshanaltica sprynari sp. nov. differs from all other species of  Cangshanaltica by following characters: (1) round anterior pronotal margins (other species have anterior pronotal margins somewhat sharp), (2) short, broad and strongly diverging vaginal palpi (other species have long, slender and parallel vaginal palpi), and (3) nearly undivided frontal calli (  C. nigra Konstantinov et al., 2013 has poorly developed frontal calli,  C. siamensis Damaška &amp; Konstantinov, 2016 has distinctly divided triangular frontal calli). The species differs from  C. nigra in brown coloration (  C. nigra is black), in the shape of the aedeagus (  C. nigra has the apex of the aedeagus gradually narrowing,  C. sprynari has a narrow apex of the aedeagus, distinctly divided by a visible, abruptly narrowing step), in the shape of vaginal palpi (  C. nigra has parallel and long vaginal palpi, vaginal palpi of  C. sprynari are short, broad and strongly diverging), development of frontal calli (in  C. nigra , frontal calli are nearly invisible) and metatarsomere III long (in  C. nigra , the metatarsomere III is very short). The species also differs from  C. siamensis in the shape of the aedeagus (  C. siamensis has a distinctly pointed apex) and in having a bulbose spermathecal receptacle (  C. siamensis has a slender receptacle). </p>
            <p>Description. Habitus (Figs 1 A–C). Body 1.7 mm long, 1.3 mm wide in maximum, oval-rounded in dorsal view, convex in lateral view, 1 mm high in maximum. Color of both ventral and dorsal body surface dark brown, legs light brown, eyes black.</p>
            <p>Head nearly hypognathous. Frontal calli present, flat, feebly visible, indistinctly divided, distinctly surrounded ventrally and dorsally by longitudinal impressions. Interantennal space wide. Antennae with 11 antennomeres, antennomeres I–V and XI light brown, antennomeres VI–X darker. Antennomere VII bearing distal protrusion anteriorly.Antennomere I triangular, antennomere II oval, antennomeres III–XI regularly elongate. Maxillary palpi light brown. Frontal ridge broad, flat. Clypeus bearing two groups of three setae each, situated symmetrically on each side. Labrum bilobed, with incision reaching ¼ of labrum length, bearing six large setae in posterior parts and some scattered smaller setae on anterior margin.</p>
            <p>Thorax. Pronotum convex, twice as wide as long, sparsely covered with shallow punctures, anterior pronotal margins strongly rounded, posterior pronotal edges sharp. Elytra strongly convex with irregular punctation, punctures larger and deeper than those on pronotum. Metathoracic wings and humeral calli absent. Metatibiae curved in dorsal view, pilose, with exterior row of teeth reaching from proximal ¼ of length of metatibia to apex. Metatibial teeth gradually elongate apically. Metatarsus attached on metatibia in deep apical impression surrounded externally by long external teeth and internally by short apical row of long teeth. Metatarsomere I 2–3× longer than II, metatibial apical tooth as long as metatarsomere II.</p>
            <p>Abdomen with five distinct ventrites. Ventrite I as long as II and III combined, with II slightly longer than III. Longitudinal ridge on ventrite I long, reaching 2/3 of its length.</p>
            <p>Genitalia. Aedeagus (Figs 2 H–I) long, curved and broad in lateral view, parallel-sided in ventral view, apex abruptly narrowed in step-like fashion in apical eighth of aedeagus. Spermathecal pump long, receptacle bulbose, duct simple, short, directed parallel with the receptacle, reaching ½ of receptacle length (Fig. 2D). Vaginal palpi short, broad, strongly diverging, bearing group of long setae (Fig. 2E). Tignum long, slender, simple (Fig. 2F).</p>
            <p>Etymology. The species is named in honor of Pavel Špryňar, a Czech botanist and entomologist, who has contributed to Czech entomology by hosting an entomological club for children in Prague.</p>
            <p> Biology. The specimens were collected at night, walking on the surface of a thin layer of moss covering stones in secondary forest growth and orchard, near Wang Tong village, Lantau, Hong Kong (Figs 7 A–B).  Cangshanaltica sprynari sp. nov. appears to be active only at night, they usually begin to occur two hours after dusk (P. Aston frequently visits the locality during the day and early evening, finding no specimens) and only in periods of humidity or rainfall, never found when the moss is totally dry. One specimen was collected, with many other terrestrial beetles, in a stream after being washed away in heavy rainfall. </p>
            <p> Host plant. One of us (PA) found the beetles feeding on moss  Fissidens sp.,  Fissidentaceae (Figs 7 C–D). Also the gut contained the residua of moss (Fig. 7E). </p>

            <p> Clavicornaltica Scherer, 1974</p>
            <p> The genus  Clavicornaltica is represented by very small (0.6–1.5 mm long), round and strongly convex beetles of brown to nearly black color. The genus is simply distinguishable from all other Oriental flea beetle genera by the presence of clavate antennae, which are unique among Alticini – the only other genus with clavate antennae and rounded, tiny body shape known to date is  Kiskeya Konstantinov &amp; Chamorro-Lacayo, 2006 . This genus is distributed in the Carribean and is not likely related to  Clavicornaltica (KONSTANTINOV &amp; CHAMORRO- LACAYO 2006). The identification of  Clavicornaltica species is, however, extremely difficult. First described species (SCHERER 1974) were documented without the description of genitalia, because the dissection of genitalia is very complicated.  Clavicornaltica species are generally uniform externally, however vary in small details of their bodies which led to a erroneously wide concept of every species and multiple forms (‘formA’,‘form B’, etc.) were described to demonstrate small morphological nuances, which were understood as intraspecific variability (MEDVEDEV 1996). However, recent studies (KONSTANTINOV &amp; DUCKETT 2005, SUENAGA &amp; YOSHIDA 2016) revealed that  Clavicornaltica species are externally similar, but can be distinguished by examination of their genitalia. The former broad concept of  Clavicornaltica species was therefore abandoned and new species are diagnosed primarily by characters on both male and female genitalia. However, this study shows that also careful searching for external characters is necessary in  Clavicornaltica studies, because in one collecting event, multiple externally uniform species can be found. </p>

            <p> Differential diagnosis. This species is very similar to two species described from Vietnam –  C. longsheng Konstantinov &amp; Duckett, 2005 and  C. vietnamensis Konstantinov &amp; Duckett, 2005 in having an unusual shape of spermatheca with a long, slender receptacle. From  C. longsheng , it differs by following characters: (1) posterior process of the metaventrite only slightly convex in the middle (in  C. longsheng , the metaventrite has a high ridge in its middle part); (2) long receptacle and pump of spermatheca with spermathecal duct directed to the pump (in  C. longsheng , the pump is wider, the receptacle shorter and the duct is initially directed downwards and after running length of the receptacle, it is curved back to its base); (3) long vaginal palpi with three apical setae (in  C. longsheng , vaginal palpi have four apical setae). From  C. vietnamensis , the new species differs in following characters: (1) base of the spermathecal duct situated before the apex of the receptacle (in  C. vietnamensis , the duct base is situated directly on the apex of the receptacle); (2) slender, not widening apices of vaginal palpi (in  C. vietnamensis , apices of vaginal palpi are somewhat widened); (3) body very convex dorsoventrally (in  C. vietnamensis , the body is less convex dorsoventrally, especially the elytra); (4) aedeagus robust, basal opening wide, basal part of the median lobe slender, apex of the aedeagus flat (in  C. vietnamensis , orificium basale is slender and the shape of the median lobe gradually narrows from the base to apex, apex of aedeagus is pointed). In the shape of the body, the species is very similar to sympatric  C. longipenis sp. nov. , but differs in having (1) metaventral process slightly convex with deep punctures on basal margins of the process (Fig. 3C), while in  C. longipenis , metaventrite is very flat, wide and nearly impunctate (Fig. 4C); (2) wide and short aedeagus with flat apex (in  C. longipenis , aedeagus is extremely slender with very elongate orificium basale and pointed apex); (3) C-shaped spermatheca with slender receptacle and voluminous pump (in  C. longipenis , spermatheca has bulbose receptacle and a small, slender pump); (4) male macropterous (in  C. longipenis , male is brachypterous); (5) intercoxal abdominal process arrow-like, nearly pointed (Fig. 5A), while in  C. longipenis , intercoxal abdominal process has flat apex (Fig. 5B); (6) antennomere XI nearly rectangular (Fig. 5D), while in  C. longipenis , antennomere 11 has elongated posterior edge (Fig. 5E). </p>

            <p> Differential diagnosis. The new species is similar to the Taiwanese  Clavicornaltica mizusawai Suenaga &amp; Yoshida, 2016 . It resembles it in having (1) a short, projecting, U-shaped spermathecal duct (in  C. mizusawai , the duct follows closely the receptacle and exceeds ½ of the receptacle length), and (2) aedeagus slender, very long, strongly curved and pointed apically, orificium basale extremely long and slender, forming 2/3 of the total length of the aedeagus (in  C. mizusawai , the aedeagus is short and robust, not very curved apically, with orificium basale wide and a round, dull apex). The spermatheca of  C. longipenis is also somewhat similar to spermatheca of  C. takizawai Döberl, 2009 , but in  C. takizawai , the duct is very simple, following parallel to the receptacle (in  C. longipenis , the duct is shorter and U-shaped).  Clavicornaltica longipenis also conspicuously differs from  C. takizawai in having an impunctate frons (  C. takizawai has a strongly punctate frons) and by the morphology of the aedeagus (in  C. takizawai , aedeagus is shorter and broad, similarly to  C. mizusawai in proportions and not curved apically). Externally, the new species resembles sympatrically living  C. doeberli sp. nov. , see the diagnosis of the latter species. The species also resembles  C. dali Konstantinov &amp; Duckett, 2005 in having flightless males and an extremely long orificium basale of aedeagus, but in  C. dali , the aedeagus is robust and strongly widened before apex (in  C. longipenis , aedeagus is only slightly widened, nearly paralell-sided, and very slender). </p>
            <p>Description. Habitus (Figs 4 A–C). Body round, very convex in lateral view, 1.1 mm long, 0.8 mm wide in maximum, 0.6 mm of maximum height. Color of dorsal surface dark reddish brown, ventral parts of thorax darkened, appendages yellowish to reddish brown.</p>
            <p>Head hypognathous, triangular. Vertex and frons impunctate, frons with extremely feebly visible small frontal calli. Eyes small, eye diameter equal to or smaller than interantennal distance. Eyes connected to antennal insertions by deep groove, frons bare, frontal groove disappearing between antennal insertions. Clypeus feebly narrowed with groups of setae between antennal insertions and margin of clypeus. Labrum incised, with two pairs of long setae. Antennae forming club, yellowish brown. Antennomere I triangular, bulbose, antennomere II long, triangular, narrowing apically, antennomere III equally long or slightly shorter than II, slender, slightly curved, antennomere IV extremely short and nearly reduced, antennomeres V and VI short and small, antennomere VII slightly broader than VI, antennomeres VIII and IX short and strongly widening, antennomere X broad, but shorter and longer than IX, antennomere XI round triangular, incised apically. Antennomeres VII–XI forming antennal club. Antennomeres I–III covered with few scattered setae, antennal club densely pilose by white setae. Clypeus feebly narrowed with groups of some setae between antennal insertions and margin of clypeus. Labrum incised, with two pairs of long setae.</p>
            <p>Thorax. Pronotum convex, 2.1× as wide as long. Elytra convex, slightly punctate, punctures arranged in 11 regular rows, puncture size gradually decreases towards elytral apex. Epipleura wide, reaching 4/5 of elytra. Tibiae slightly curved, widened apically. Metatibia with apical spur with one, two or none wide teeth. Metaventrite flat. Metaventral process long, rounded, wide, reaching beyond mesocoxae and covering entire surface of mesoventrite, flat with shallow marginal row, forming small punctures basally, and with developed marginal edge, surface shining with some scattered setae. Males brachypterous with wing reduced to small winglets (Fig. 5C), females wingless.</p>
            <p>Abdomen with five ventrites (Fig. 5B). Intercoxal process of ventrite I with short, wide apex. Anterior margins of ventrite I with row of deep punctures. Carina of ventrite I surrounded by deep punctures at base of intercoxal process, intercoxal process impunctate.</p>
            <p>Genitalia. Aedeagus (Figs 4 G–H) extremely long, orificium basale reaching thorax, slender, curved apically, orificium basale extremely long and slender, forming 1/2 to 2/3 of the total length of aedeagus.Apex of aedeagus pointed. Spermatheca (Fig. 4D) small, with slender pump and bulbose receptacle, duct short, very robust, U-shaped. Vaginal palpi (Fig. 4F) connected basally, long, slender, bearing 3 long setae apically. Tignum (Fig. 4E) strong, long.</p>
            <p>Etymology. The name of the species is inferred from the latin adjective longus meaning ‘long’ and noun penis, referring to the unusually long aedeagus of the species. The name is a noun in apposition.</p>

            <p> Ivalia excavata (Wang, 1993)</p>
            <p>(Fig. 6 A–G)</p>
            <p> Taizonia excavata Wang, 1993 in WANG &amp; YU (1993: 321, 329) (original description). </p>
            <p> Ivalia excavata: DUCKETT et al. (2006: 51) (new combination) </p>
            <p>Material examined. China: Hong Kong – New Territories, Shing Mun, moss, night time, 1.v.2009, 1 ♀, Paul Aston lgt. (NMPC).</p>
            <p> Remarks. Specimen identified as  Ivalia excavata is the only member of the genus  Ivalia collected in Hong Kong. It can be distinguished from similar  Cangshanaltica by having the anterolateral pronotal setiferous pore placed near to the pronotal apex and by lacking any protrusion on antennomere VII. The specimen is also very easily distinguishable from  C. sprynari sp. nov. by their light orange color with black spots on elytra and greater size. </p>
            <p> The species  Ivalia excavata is known from Hunan Province, China. We compared the specimen with pictures of the holotype deposited in Institute of Zoology, Chinese Academy of Sciences, Beijing. Another two species of  Ivalia have been described from mainland China (KIMOTO &amp; GRESSIT 1973). The specimen collected in Hong Kong is, also very similar to one of those species –  I. maculata (Kimoto &amp; Gressitt, 1973) based on the comparison with the original description. The identity of the specimen should be considered carefully because of the high endemism of  Ivalia species and also the identity of the species needs to be revised (we were unable to study the holotype of  I. maculata deposited in Bishop Museum, Honolulu, Hawaii). However, the specimen from Hong Kong differs from the original description of  I. maculata in size (  I. maculata is about 1.8 mm long, Hong Kong specimen is about 2.3 mm long) and coloration (  I. maculata seem to have dorsal surfaces and legs darker than specimen from Hong Kong). Genitalia were not illustrated in the original descriptions and cannot be compared. In this paper, we provide detailed pictures of  Ivalia excavata specimen from Hong Kong for the first time, including pictures of female genitalia (Figs 6 A–G). Further revision should reveal the correct status of this specimen. </p>
