03A0B765FFCDFF81FED51622FCF9FE20.taxon	discussion	Comment: The - extremely short - original description of Lathrobium unicolor is based on an unspecified number of syntypes from “ India orientale, praecipue boreali ” collected by “ Dom. Bacon ” (Kraatz 1859). Four syntypes, one male and three females, were located in the Kraatz collection at the SDEI. They had lectotype and paralectotype labels by V. Gusarov attached to them, but since a lectotype designation had not been published, these labels were removed to avoid confusion. The male is here designated as the lectotype; its aedeagus is illustrated in Figs 1 - 2. Lathrobium testaceum was described from an unspecified number of syntypes from “ Indes orientales ” (Motschulsky 1858). This name is a junior primary homonym and was subsequently replaced with L. pallens by Gemminger & Harold (1868). Lathrobium pallens and L. testaceum have been treated as synonyms of L. unicolor at least since Fauvel (1904). In the original description of L. chujoi, which is based on a “ Type, ♀ ” [sic] and eleven paratypes from “ Thailand: Nakon Sawan (Last 1966), there is no reference whatsoever to Pseudolathra unicolor. An examination of three paratypes revealed that they are conspecific with P. unicolor, hence the synonymy proposed above. The aedeagus of a male paratype is illustrated in Figs 5 - 6.

03A0B765FFCDFF81FED51622FCF9FE20.taxon	description	Redescription: Body length 5 - 6 mm; length of forebody 2.7 - 3.0 mm. Coloration variable: body either uniformly reddish or partly (head, postero-lateral portion of elytra, abdominal segments III-VI) more or less distinctly infuscate; legs yellowish to reddish-yellow; antennae reddish. Head approximately as broad as long or weakly transverse; punctation coarse and sparse, in median dorsal portion very sparse or absent; interstices without microsculpture and glossy. Eyes large, but of variable size, usually somewhat longer, rarely shorter than postocular region in dorsal view. Antennae slender, 1.8 - 2.0 mm long; all antennomeres oblong. Pronotum of somewhat variable shape, 1.1 - 1.2 times as long as broad and approximately 1.1 times as broad as head; on either side of the impunctate midline with series of 15 - 20 punctures, these punctures often accompanied by additional punctures; punctation of lateral portions sparse to moderately dense; interstices without microsculpture. Elytra approximately as long as pronotum or slightly longer; laterally with fine and almost complete submarginal carina; punctation arranged in more or less pronounced series; interstices without microsculpture. Hind wings fully developed. Abdomen slightly narrower than elytra; punctation very fine and very dense; interstices with microsculpture; posterior margin of tergite VII with palisade fringe. ♂: protarsomeres I-IV strongly dilated; sternite VII without distinctly modified pubescence and shallow median impression, posterior margin broadly concave (Fig. 9); sternite VIII oblong, posterior excision narrow and deep, not quite reaching middle of sternite (Fig. 10); aedeagus 1.15 - 1.30 mm long, shaped as in Figs 1 - 8. ♀: protarsomeres I-IV distinctly dilated, but slightly less so than in male. Intraspecific variation: This species is highly variable, particularly in coloration, density of punctation, eye size, shape of head and pronotum, to some extent also in the size of the aedeagus. In material from India, the body is usually of uniformly reddish coloration, whereas in specimens seen from Myanmar and China the head and the postero-lateral portion of the elytra are often more or less distinctly infuscate; occasionally the head may even be black. In most specimens the eyes are large, bulging, and longer than the postocular region; in the male from China, however, they are less convex and shorter than the postocular region. The variation of the aedeagus is illustrated in Figs 1 - 8.	en	Assing, V. (2012): The Pseudolathra species of the East Palaearctic and the Oriental regions (Coleoptera: Staphylinidae: Paederinae).

03A0B765FFCDFF81FED51622FCF9FE20.taxon	distribution	Distribution and natural history: The species is evidently widespread in the southern East Palaearctic and Oriental regions. Malebased records have been seen from Nepal, North India, Myanmar, Bangladesh, China, and Thailand (Map 1). Owing to possible confusion with externally similar species (P. himalayana, P. villiersi, etc.), all previous records and all the female-based records listed above should be considered doubtful. On at least two occasions, P. unicolor was collected at light traps in May and November. In one locality in southern central Nepal, the species was found together with P. himalayana and P. pulchella. One specimen from China was taken on the shore of a reservoir.	en	Assing, V. (2012): The Pseudolathra species of the East Palaearctic and the Oriental regions (Coleoptera: Staphylinidae: Paederinae).

03A0B765FFC2FF83FF69161EFF65FAD0.taxon	description	Description: Body length 5 - 6 mm; length of forebody 2.7 - 3.0 mm. Coloration variable: body uniformly reddish or partly (head, posterior portion of elytra, abdominal segments III-VI) more or less distinctly infuscate; legs yellowish to pale reddish; antennae reddish. Of similar external appearance and as variable as P. unicolor; reliably distinguished only by the male sexual characters. ♂: sternite VII in the middle with rather extensive impression, setae in this impression directed obliquely postero-mediad, posterior margin very weakly concave (Fig. 11); sternite VIII of similar shape as in P. unicolor, but midline without setae (Fig. 12); aedeagus 1.0 - 1.1 mm long, shaped as in Figs 13 - 14. Comparative notes: As can be inferred from the similar external morphology and particularly by the similar male sexual characters (shape and chaetotaxy of sternite VIII; general morphology of the aedeagus), P. himalayana is closely allied to and probably the adelphotaxon of P. unicolor, with which it was previously confounded. It is distinguished from P. unicolor especially by the differently shaped (both in lateral and in ventral view) and smaller aedeagus.	en	Assing, V.

03A0B765FFC4FF87FF6915A2FD81F98A.taxon	description	Description: Body length 5 mm; length of forebody 2.7 mm. Coloration: head blackish-brown; pronotum and elytra reddish; abdomen reddish, with segments III-VI slightly darker; legs and antennae reddish-yellow. Head approximately as long as broad, tapering behind eyes; posterior angles weakly marked; punctation coarse and sparse. Eyes bulging, slighly longer than postocular region in dorsal view. Antennae 1.8 mm long. Pronotum 1.15 times as long as broad and 1.1 times as broad as head; dorsal series composed of approximately 15 punctures and some additional punctures; lateral portions with sparse punctation. Elytra nearly as long as pronotum; punctation arranged in straight series. Hind wings fully developed. Abdomen narrower than elytra; punctation dense and fine; interstices with microsculpture; posterior margin of tergite VII with palisade fringe. ♂: protarsomeres I-IV strongly dilated; sternite VII with weakly concave posterior margin, pubescence unmodified (Fig. 29); sternite VIII oblong, posterior excision narrow and deep, its depth nearly 2 / 5 the length of sternite (Fig. 30); aedeagus 1.0 mm long, similar to that of P. villiersi, but apex of dorsal plate somewhat heart-shaped in ventral view (Figs 31 - 32). Comparative notes: The similarly derived morphology of the aedeagus suggests that P. cordiformis is closely allied to P. villiersi. Both species are reliably distinguished only by the shape of the aedeagus, particularly that of the apex of the dorsal plate.	en	Assing, V.

03A0B765FFD9FF9CFED514A2FD3AFA96.taxon	discussion	Comment: Lathrobium pulchellum was described from an unspecified number of syntypes from “ Ceylan ” (Kraatz 1859). Four type specimens were located in the collections of the SDEI. They have (para-) lectotype labels by V. Gusarov attached to them, but a designation was never published. In view of the fact that all the available type specimens are females and probably conspecific, a lectotype designation does not seem advisable. Lathrobium pulchellum was synonymised with L. caffrum Boheman, 1848 by Fauvel (1903), a species whose original description is based on an unspecified number of syntypes from “ Caffraria orientali ” (Boheman 1848). Repeated loan requests addressed to the curator in charge at the natural history museum in Stockholm, where the Boheman collection is deposited, remained unanswered. Last (1966) figured the aedeagus of what he regarded as P. caffra, but failed to state if he had seen type material and what specimen his illustrations were based on. In any case, they show that the male he studied is not conspecific with the present interpretation of the P. pulchella, but probably with P. vellicans. An examination of material from Kenya (one male and one female) and from South Africa (two females), which had been identified by Cameron as P. caffra, revealed that this material represents an externally highly similar and, based on the similar general morphology of the male sexual characters, closely related, but nevertheless distinct species. Furthermore, it is often impossible to reliably distinguish Pseudolathra species based on external characters alone, and the male sexual characters of true P. caffra had never been examined and illustrated. Therefore, it seems most unlikely that both names should refer to the same species and, until there is evidence proving otherwise, P. pulchella is revalidated. For illustrations of the aedeagus of P. caffra from Kenya see Figs 35 - 37. Cameron (1940) described Lathrobium caffrum javanum based on “ two examples ” from “ S. Java: Tjilatjap ”, stating that this subspecies was distinguished from the nominate subspecies by slightly smaller size, different coloration, and denser punctation of the head and pronotum. Only one syntype was located in the Cameron collection, although, according to the original description, both syntypes were deposited there. In external characters, the examined syntype is indistinguishable from material seen, e. g., from northern India. Hence the synonymy proposed above. Additional material examined:	en	Assing, V.

03A0B765FFD9FF9CFED514A2FD3AFA96.taxon	description	Redescription: Body length 5.7 - 7.0 mm; length of forebody 3.1 - 3.8 mm. Coloration variable: head usually blackish-brown to blackish, rarely reddish-brown; pronotum reddish; elytra usually blackishbrown to blackish (sometimes with weak bluish hue), rarely reddish-brown; abdomen uniformly reddish to uniformly blackish-brown, sometimes reddish with darker apex (segments VII-X); legs reddish; antennae reddish to brown. Head approximately as broad as long; posterior angles usually broadly convex, weakly marked; punctation coarse and sparse, in median dorsal portion very sparse or absent; interstices without microsculpture and glossy. Eyes large, slightly shorter than distance between posterior margin of head and neck in dorsal view. Antennae slender, 2.0 - 2.4 mm long; all antennomeres oblong. Pronotum of somewhat variable shape, 1.15 - 1.25 times as long as broad and usually 1.00 - 1.05 times as broad as head; on either side of the impunctate midline with series of 15 - 20 punctures, these punctures often accompanied by additional punctures; punctation of lateral portions sparse to moderately dense; interstices without microsculpture. Elytra approximately as long as pronotum or indistinctly shorter; laterally with fine and almost complete submarginal carina; punctation arranged in distinct series; interstices without microsculpture. Hind wings fully developed. Protarsomeres with very weakly pronounced sexual dimorphism, in both sexes strongly dilated, only slightly less so in female than in male. Abdomen slightly narrower than elytra; punctation very fine and very dense; interstices with microsculpture; posterior margin of tergite VII with palisade fringe. ♂: sternite VII without distinctly modified pubescence and shallow median impression, posterior margin truncate (Fig. 38); sternite VIII oblong, posterior excision narrowly V-shaped and deep, not quite reaching middle of sternite (Fig. 39); aedeagus 1.0 - 1.2 mm long, shaped as in Figs 33 - 34; ventral process of aedeagus conspicuously laterally compressed and apical portion of dorsal plate of distinctive shape. Comparative notes: Pseudolathra pulchella is distinguished from the preceding species by slightly larger body size, on average darker coloration of the elytra and of the head, an on average more oblong pronotum, the slightly broader posterior excision of the male sternite VIII, and by the completely different morphology of the aedeagus. It is readily separated from P. nigerrima and P. regularis by external characters alone, especially by the different coloration (P. nigerrima and P. regularis: body completely blackish).	en	Assing, V.

03A0B765FFD9FF9CFED514A2FD3AFA96.taxon	distribution	Distribution and natural history: This species is remarkably widespread, its revised distribution ranging from Nepal to Sri Lanka, Thailand, Malaysia, and Indonesia (Map 3). According to Fauvel (1903) and Cameron (1931), it has been recorded also from other parts of the Oriental region. However, in view of the similarity to other species, all previous records and all female-based records above should be considered doubtful. Little is known about the habitat of this species. The highest altitude specified on the labels of the examined material is 500 m. On several occasions, the species was collected with light traps in March, May / June, and November. In one locality in southern central Nepal, the species was found together with P. unicolor and P. himalayana.	en	Assing, V.

03A0B765FFDCFF91FF69111CFDD1FAA0.taxon	description	Description: Large species: body length 9.0 - 10.5 mm; length of forebody 4.5 - 5.0 mm. Coloration: head and pronotum black, with the posterior and often also the anterior margins diffusely dark-reddish; elytra reddish to reddish-brown, posteriorly often weakly and diffusely infuscate; abdomen black, with the posterior and lateral margins of the tergites reddish; legs dark-yellowish; antennae reddish. Head (Fig. 52) strongly transverse, approximately 1.2 times as wide as long; posterior angles obtusely marked; dorsal surface conspicuously glossy, almost impunctate, except for the sparse micropunctation and for a few coarse macropunctures near eyes and near posterior margin. Eyes large and bulging, approximately 3 times as long as postocular region in dorsal view. Antenna approximately 3.2 - 3.5 mm long; antennomeres III-X with very narrow bases, distinctly dilated apically. Pronotum (Fig. 52) usually weakly transverse, 1.00 - 1.05 times as broad as long and slightly wider than head; dorsal series composed of usually 5 - 6 coarse punctures; lateral portions with very sparse coarse punctures; surface glossy and with sparse micropunctation. Elytra (Fig. 53) nearly as long as pronotum; laterally with fine and complete submarginal carina; punctation arranged in three series, one along suture, one in the middle, and one near lateral margin; interstices with micropunctation and glossy. Hind wings fully developed. Protarsomeres without appreciable sexual dimorphism, in both sexes strongly dilated. Abdomen distinctly narrower than elytra; punctation moderately coarse and dense on tergite III, gradually becoming finer and less dense on tergites IV-VII; interstices with shallow microsculpture, but glossy; posterior margin of tergite VII with palisade fringe. ♂: sternite VII with distinctly concave posterior margin (Fig. 57); sternite VIII oblong, posterior excision narrow and deep, its depth approximately 2 / 5 the length of sternite (Fig. 58); aedeagus large, 1.4 - 1.5 mm long, with short ventral process with apex of triangular shape and subapically with two minute teeth (lateral view) (Figs 53 - 56). Intraspecific variation: Slight differences between the males from Thailand and those from northern India were observed in the morphology of the aedeagus (see Figs 53 - 54 and Figs 55 - 56, respectively). However, the two specimens from northern India were collected almost a century ago and the apical parts of the aedeagus are somewhat (semi-) membranous, so that the observed differences may be based on artefacts. Moreover, the distance between Thailand and northern India is considerable, which would account for some clinal variation, and the differences between the aedeagi of different species are usually rather pronounced. Therefore, in the absence of additional morphological evidence, the observed differences are attributed to intra- rather than interspecific variation. More material, particularly from northern India, is needed to clarify if the observed differences are constant. Comparative notes: Pseudolathra transversicollis is distinguished from all other Palaearctic and Oriental congeners by larger size, the distinctive coloration, the usually slightly transverse pronotum, the shape of the male sternite VII, and by the shape of the aedeagus. Based on the similarly derived morphology of the aedeagus and similar external characters, P. transversicollis is undoubtedly most closely related to P. nigerrima, apparently its adelphotaxon. From this species, it is additionally separated by the different shape and chaetotaxy of the male sternite VII.	en	Assing, V.

03A0B765FFD2FF93FF69119FFE7DFBD4.taxon	description	Description: Body length 6.5 - 7.5 mm; length of forebody 3.5 - 4.0 mm. Habitus as in Fig. 59. Coloration: body black; legs dark-yellowish; antennae pale-reddish. Head (Fig. 60) strongly transverse, 1.20 - 1.25 times as wide as long; posterior angles obtusely marked; dorsal surface conspicuously glossy, almost impunctate, except for a few punctures near eyes and near posterior margin. Eyes large and bulging, 3 - 4 times as long as postocular region in dorsal view. Antenna approximately 2.3 mm long; antennomeres III-X with very narrow bases, distinctly dilated apically. Pronotum (Fig. 60) almost as broad as long and approximately as broad as head; dorsal series composed of usually 5 - 6 coarse punctures; lateral portions with very sparse coarse punctures; surface conspicuously glossy. Elytra (Fig. 60) 0.90 - 0.95 times as long as pronotum; laterally with fine and complete submarginal carina; punctation arranged in three series, one along suture, one in the middle, and one near lateral margin; interstices without microsculpture and very glossy. Hind wings fully developed. Protarsomeres without appreciable sexual dimorphism, in both sexes strongly dilated. Abdomen distinctly narrower than elytra; punctation rather coarse and very dense on tergite III, gradually becoming finer and less dense on tergites IV-VII; interstices without microsculpture and glossy; posterior margin of tergite VII with palisade fringe. ♂: sternite VII not distinctly modified; sternite VIII oblong, posterior excision narrow and deep, not quite reaching middle of sternite (Fig. 63); aedeagus 1.0 - 1.1 mm long, slender, with apically deeply bifid ventral process, and with apically somewhat arrow-shaped dorsal plate in ventral view (Figs 61 - 62). Comparative notes: In external appearance, P. sagittata somewhat resembles P. nigerrima, from which it is distinguished by smaller size (no overlap), paler legs, the distinctly coarser punctation of the anterior abdominal tergites, as well as by the sexual characters, particularly the completely different shape of the aedeagus.	en	Assing, V.

The male syntype made available to me from the Sharp collection is designated as the lectotype. Sharp (1889) stated that L. regulare was a “ species of the L. lusitanicum group ”, which today belongs to Pseudolathra. An examination of the lectotype confirmed that the species indeed belongs to this genus. Additional material examined:	en	Assing, V.

03A0B765FFD0FF96FF69108BFD3BFCD0.taxon	description	Redescription: Body length 6.0 - 7.0 mm; length of forebody 3.2 - 3.9 mm. Habitus as in Fig. 64. Coloration: forebody blackish, with the suture indistinctly dark-reddish; abdomen blackish, sometimes with dark-reddish apex; legs and antennae pale-reddish. Head (Fig. 65) weakly oblong, approximately 1.05 times as long as broad, slightly tapering behind eyes; posterior angles rather weakly marked; dorsal surface with few macropunctures and with sparse micropunctation; interstices without microsculpture. Eyes large, approximately as long as postocular region in dorsal view, or slightly shorter. Antenna moderately slender, almost 2 mm long. Pronotum (Fig. 65) about 1.20 - 1.25 times as long as broad and approximately 1.1 times as wide as head, lateral margins almost straight, weakly converging posteriorly in dorsal view, posterior angles broadly rounded; on either side of midline with a dorsal series of 11 - 14 coarse punctures, laterad of these series with sparse macropunctures; microsculpture very sparse, micropunctation absent. Elytra (Fig. 65) approximately 0.8 times as long as pronotum, humeral angles marked; macropunctation arranged in one sutural and three dorsal series; microsculpture and micropunctation absent. Hind wings fully developed. Abdomen approximately as broad as elytra; punctation fine and dense; posterior margin of tergite VII with palisade fringe. ♂: tergite VIII strongly convex posteriorly; sternite VII without conspicuous modifications; sternite VIII weakly transverse, with rather broad and shallow posterior excision (Fig. 66); aedeagus 0.95 - 1.00 mm long, shaped as in Figs 67 - 70. Comparative notes: This species is distinguished from all other Palaearctic and Oriental species by the shallow and broad posterior excision of the male sternite VIII and by the shape of the aedeagus, from all other dark-coloured species also by the much more slender pronotum.	en	Assing, V.

03A0B765FFD0FF96FF69108BFD3BFCD0.taxon	distribution	Distribution: The species was described from Japan and subsequently reported also from China (Li & Chen 1990). In view of the external similarity of Pseudolathra species, as well as the fact that it was previously attributed to Lobrathium and that illustrations of the male sexual characters had been unavailable, there is some doubt if these records are based on correct identifications. Nevertheless, the species is present and widespread in China, as is confirmed by the above material from Shaanxi, Sichuan, Jiangsu, and Yunnan provinces.	en	Assing, V.
