( Figs 14-20 , Map 2 ) Type material: Holotype ♂ : " Nepal P: Seti , D: Bajhang , 42 km NE Chainpur , Kalapani Khola , N29°48'23'' / E81°29'04''E , 3750 m , 22.-23.VI.2009 , leg. M. Hartmann , riverside (shrub/pasture) ♂27 / Holotypus ♂ Lathrobium hartmanni sp.n. , det. V. Assing 2012" ( NME ) . Paratype ♀ : same data as holotype ( cAss ) . Etymology: The species is dedicated to Matthias Hartmann (NME), who collected the type specimens. Description: Body length 7.5-7.8 mm ; length of forebody 3.3 mm . Habitus as in Fig. 14 . Coloration: body blackish-brown; legs, except for the paler tarsi, dark-brown; antennae reddish-brown. Head ( Fig. 15 ) as long as broad; punctation moderately coarse and moderately dense, slightly sparser in median dorsal portion; interstices with distinct microreticulation, on average somewhat broader than diameter of punctures. Eyes weakly projecting from lateral contours of head, approximately 1/3 the length of postocular region in dorsal view and composed of approximately 30 ommatidia. Pronotum ( Fig. 15 ) approximately 1.18 times as long as broad and as broad as head; punctation similar to that of head, but slightly coarser; interstices without microsculpture. Elytra short, approximately 0.55 times as long as pronotum ( Fig. 15 ); humeral angles weakly marked; punctation shallow; interstices without distinct microsculpture. Hind wings completely reduced. Metatibia slightly compressed. Abdomen broader than elytra; punctation moderately fine and dense, somewhat sparser on posterior than on anterior tergites; posterior margin of tergite VII without palisade fringe; posterior margin of tergite VIII weakly convex to indistinctly pointed in the middle. ♂: protarsomeres I-IV strongly dilated; sternite VII ( Fig. 16 ) shallowly impressed posteriorly and with sparse long black setae in postero-median portion, posterior margin weakly concave; sternite VIII ( Fig. 17 ) moderately transverse, with shallow median impression, this impression with weakly modified black setae, posterior excision small, not very deep, and anteriorly concave; aedeagus ( Figs 18-19 ) 1.3 mm long, ventral process weakly curved in lateral view and gradually narrowed apicad in ventral view, dorsal plate lamellate and moderately sclerotised, internal sac with a long membranous tube. ♀ : protarsomeres I-IV strongly dilated; sternite VIII ( Fig. 20 ) oblong and with smoothly convex posterior margin; tergite IX undivided anteriorly; tergite X approximately as long as antero-median portion of tergite IX in the middle. Comparative notes: Based on the external and male sexual characters, L. hartmanni belongs to the L. muguicum species group, which previously included only L. muguicum , whose female sexual characters are unknown. Both species are externally extremely similar. The new species is distinguished from L. muguicum by the somewhat darker legs ( L. muguicum : legs and antennae reddish), the broader and not distinctly Vshaped posterior excision of the male sternite VIII, and particularly by the morphology of the aedeagus. In L. hartmanni , the aedeagus is smaller ( L. muguicum : 1.5 mm ), the ventral process is apically abruptly narrowed (ventral view), stouter (lateral view), apically curved, and somewhat truncate, and the internal tube is less massive. Distribution and natural history: The type locality is situated to the southeast of the Saipal peak in Bajhang district, Seti province , northwestern Nepal ( Map 2 ). The specimens were collected near a river bank at an altitude of 3750 m .
