( 115–122 ) and L. aculeatum COIFFAIT ( 123–129 ): habitus ( 115, 123 ); forebody ( 116, 124 ); male sternite VII ( 117, 125 ); male sternite VIII ( 118, 126 ); aedeagus in lateral and in ventral view ( 119–120, 127–128 ); female sternite VIII ( 121, 129 ); female tergites IX–X ( 122 ). Scale bars: 115–116, 123–124: 1.0 mm; 117–122, 125–129: 0.5 mm. kot, 28°51'N , 82°59'E , 3050 m , 10.IX.2012 , leg. Schmidt ( NME , cAss) . Comment : The redescription in ASSING (2012) is based only on two type specimens in rather poor condition. The above specimens render a more accurate redescription and better illustrations possible. Redescription : Body length 5.0– 6.8 mm ; length of forebody 2.3–2.9 mm ; size subject to sexual dimorphism (males larger than females). Habitus as in Fig. 123 . Coloration: body reddish, with the abdomen often somewhat darker; legs dark-yellowish; antennae reddish. Head ( Fig. 124 ) 1.03–1.05 times as long as broad; punctation rather sparse and moderately coarse; interstices on average distinctly broader than diameter of punctures, with distinct microreticulation. Eyes small, composed of approximately 10 ommatidia, approximately one-sixth as long as postocular region in dorsal view. Antenna 1.3–1.5 mm long. Pronotum ( Fig. 124 ) approximately 1.25 times as long as broad and 1.00–1.07 times as broad as head; punctation similar to that of head, but slightly denser; midline broadly impunctate; interstices without microsculpture. Elytra ( Fig. 124 ) approximately 0.6 times as long as pronotum; punctation fine and rather sparse; interstices without distinct microsculpture. Hind wings completely reduced. Protarsomeres I–IV with moderately pronounced sexual dimorphism; metatibiae and -femora unmodified. Abdomen slightly broader than elytra; punctation distinct and rather dense, sparser on tergite VIII; interstices with shallow microsculpture; posterior margin of tergite VII without palisade fringe; posterior margin of tergite VIII convex. : protarsomeres I–IV distinctly dilated; sternite VII ( Fig. 125 ) moderately transverse, with unmodified pubescence and with weakly concave posterior margin; sternite VIII ( Fig. 126 ) approximately 1.07 times as long as broad, pubescence unmodified, posterior excision moderately deep and nearly U-shaped; aedeagus ( Figs 127–128 ) approximately 1.15 mm long; ventral process extended into a long and slender spine, this spine weakly asymmetric and basally with ventral carina; dorsal plate short and membranous; internal sac without sclerotized structures. : protarsomeres I-IV moderately dilated; sternite VIII ( Fig. 129 ) approximately 1.25 times as long as broad and with convex posterior margin; tergite IX undivided in the middle, postero–lateral processes short and apically acute, barely extending beyond apex of tergite X; tergite X weakly convex in cross–section, of oval shape, and approximately 1.25 times as long as antero–median portion of tergite IX. Distribution and natural history : Lathrobium aculeatum is known from three geographically close localities in the western Dhaulagiri range ( Map 2 ). The above spec- imens, several of them teneral, were found close to the type locality, which is situated at approximately 28°51'N , 83°00'E . They were collected at an altitude of 3050 m and between 3400 and 3800 m .
