03879F6DFFF7FF92FF4014ABFF65AE17.taxon	description	ADDITIONAL MATERIAL SEEN: 1 ex.: Malaysia, Sabah, Tawau, 11 - 17. x. 2012, 4.66 N 117.6 E, 100 m Alt, Coll. C. L. Gray, SAFE project area, F. I. T Riparian forest, strip in oil palm, OUMNH - 213 - 056 (in OUMNH). TAXONOMY: This new species belongs to the nigerrima group sensu Assing 2012 according to its colour, puncturation and conformation of the aedoeagus. DESCRIPTION Length of body: 8 - 9 mm; length of fore-body: 4.2 mm. Head, pronotum and abdomen black, the posterior margins of abdominal tergites narrowly and obscurely reddish; elytra light or dark brown, the posterior third to half more or less strongly infuscate. Habitus (fore-body): Fig. 1. Labrum and antennae dark brown; legs dark testaceous. Head transverse, 4 / 5 ths wider than long, the vertex shiny, with several large setiferous punctures near eyes, a continuous transverse row of smaller punctures along base, and irregularly scattered micro-punctures on entire disc, sparser in the middle. Eyes large and salient, twice as long as temples measured to posterior angle of head. Antennae about 2.9 mm long, antennomeres 5 - 9 with very narrow bases, club-shaped. Pronotum only slightly transverse, very slightly broader than head, with an inner discal series of about 5 punctures, an outer series of 4 larger punctures, and 3 - 4 marginal punctures; sparse scattered micro-punctures exceedingly small, scarcely visible. Elytra much longer and broader than pronotum, with an entire sub-marginal carina and two rows of about 10 discal punctures each, those of outer row coarser than inner row, in addition to a juxta-sutural row of small punctures and a row of about 10 punctures on declivous lateral surfaces. Pro-tarsi broadly dilated in both sexes. Abdomen a little narrower than elytra, finely and not very densely punctuate. Male: abdominal sternite VII (Fig. 1 b) with a small, shallow apical emargination; sternite VIII (Fig. 1 c) with a deep narrow emargination. Aedoeagus (Fig. 1 a) characteristic, the dorsal blade very broad, apically sub-truncate, about as long as ventral blade, the latter with a conspicuous inwardly curving apical process on either side, and a sub-apical process bearing two ventral and two lateral spines.	en	Rougemont, Guillaume de (2014): Two new species of Pseudolathra Casey from Borneo (Coleoptera, Staphylinidae, Paederinae).

03879F6DFFF7FF92FF4014ABFF65AE17.taxon	discussion	REMARKS: P. borneensis n. sp. most closely resembles P. transversicollis Assing from Thailand and P. separanda Assing from north India, especially in the colour of the elytra, but is a smaller insect than either of those and with a characteristic aedoeagus.	en	Rougemont, Guillaume de (2014): Two new species of Pseudolathra Casey from Borneo (Coleoptera, Staphylinidae, Paederinae).

03879F6DFFF4FF94FF5F15CCFE44AE17.taxon	description	TAXONOMY: This new species also appears to belong to the nigerrima group according to its colour, size and puncturation, but has an aberrant type of aedoeagus. DESCRIPTION Length of body: 7 - 7.6 mm; length of fore-body: 3.8 mm. Body entirely black; palpi, antennae and tarsi dark testaceous; femora and tibiae infuscate, the femora more strongly so. Habitus (fore-body): Fig. 2. Head transverse, 4 / 5 ths wider than long; vertex shiny, with 3 - 4 large setiferous punctures near inner anterior margin of eyes, another on margin of eye posteriorly, another behind eye, and a continuous row of small punctures along basal margin. Eyes very large, more than twice as long as temples measured from posterior margin of eye to posterior angles of head. Antennae about 2.4 mm long. Pronotum scarcely elongate, 4 / 5 ths longer and about as broad as head, with a discal series of 5 large punctures, an outer series of 3 punctures slightly divergent posteriorly to inner series, 3 punctures near lateral margin in anterior half of pronotum, besides a few small punctures on lateral margin itself. Elytra longer and broader than pronotum, with a juxta-sutural series of 8 - 10 small punctures, an inner discal series of 8 - 10 larger punctures, an outer series of 9 - 10 punctures, and a series of 7 - 8 punctures on lateral declivity of elytra. Hind wings fully developed. Abdomen much narrower than elytra, shiny, sparsely punctate. Male: abdominal sternite VII (Fig. 2 b) with a fairly large broad apical emargination, its lateral angles salient and furnished apically with a number of small black bristles; sternite VIII (Fig. 2 c) with a deep, narrow sub-parallel-sided emargination extending to half the length of sternite; aedoeagus (Fig. 2 a) with a long lanceolate dorsal blade of the median lobe, the ventral blade short, bi-lobed. Pseudolathra borneensis (1) fore-body. (1 a) Aedoeagus in ventral view. (1 b) Male sternite VII. (1 c) Male sternite VIII. Pseudolathra lanceolata (2) fore-body. (2 a) Aedoeagus in ventral view. (2 b) Male sternite VII. (2 c) Male sternite VIII. (3) Pseudolathra. species indet. cf. lanceolata, aedoeagus in ventral view.

03879F6DFFF4FF94FF5F15CCFE44AE17.taxon	discussion	REMARKS: This new species superficially most closely resembles P. nigerrima, but is on average a little smaller, of the same colour but with darker legs, and differs morever in its more transverse head, the puncturation of the pronotum, and the completely different aedoeagus.	en	Rougemont, Guillaume de (2014): Two new species of Pseudolathra Casey from Borneo (Coleoptera, Staphylinidae, Paederinae).
