The Pseudolathra species of the East Palaearctic and the Oriental regions (Coleoptera: Staphylinidae: Paederinae) Author Assing, V. text Beiträge Zur Entomologie = Contributions to Entomology 2012 2012-12-20 62 299 330 journal article 2537 10.21248/contrib.entomol.62.2.299-330 63d99f1a-3ec7-4d97-a0d4-d7f23c214113 0005-805X 5873469 Pseudolathra brevincisa sp. n. ( Figs 20-24 , Map 1 ) Type material: Holotype ♂ : “151 / Bangkok / inconnue / Lathrobium n.s. Bangkok / Sharp Coll 1905-313 / Holotypus ♂ Pseudolathra brevincisa sp. n. , det. V. Assing 2012” ( BMNH ). Etymology: The specific epithet is composed of the Latin adjectives brevis (short) and incisa (incised), and refers to the shape of the posterior incision of the male sternite VIII, one of the characters distinguishing this species from the similar P. unicolor . Description: Body length 4.7 mm ; length of forebody 2.7 mm . Coloration: head dark-brown; remainder of body reddish; legs yellowish; antennae reddish yellow. In external characters highly similar to P. unicolor ( Fig. 20 ) reliably distinguished only by the male primary and secondary sexual characters: ♂ : sternite VII not distinctly modified; sternite VIII oblong, posterior incision moderately deep, its depth little more than one third of length of sternite ( Fig. 21 ); aedeagus small, 0.75 mm long and of very distinctive shape ( Figs 22-23 ), ventral process apically bifid ( Fig. 24 ). Comparative notes: This species is reliably distinguished from L. unicolor , L. himalayana , and other similar species only by the morphology of the aedeagus and the relatively short posterior excision of the male sternite VIII. Distribution: Pseudolathra brevincisa is currently known only from the type locality in Thailand ( Map 1 ).
