Additional material examined: Nepal: 2 exs., Annapurna South Himal, SE Narcheng, left river side of Bele Khola, 28°31'N, 83°42'E, 2300 m, 25.-26.V.2001, leg. Hirthe(cHir, cAss). The known distribution of Habrocerus indicusis confined to northern Indiaand Nepal( ASSING & WUNDERLE 1995, 1996). Habrocerus splendens sp. n. ( Figs 1-11, Map 1) Type material: Holotype: " China: Yunnan[CH07-17], Baoshan Pref., mountain range 25 kmS Tengchong, 1900 m, 24°48'28"N, 98°32'03"E, dev. primery [sic] decid. forest, litter, fungi sifted, 2.VI.2007, M. Schülke/ Holotypus Habrocerus splendens sp. n.det. V. Assing2007" (cAss). Paratypes: 1 : " China: Yunnan[CH07-18], Baoshan Pref., mountain range 22 kmS Tengchong, 1750 m, 24°49'29"N, 98°29'27"E, second. forest, litter, dead wood sifted, 2.VI.2007, M. Schülke" (cSch); 1 , 1 : " China: Yunnan[CH07-18], Baoshan Pref., mountain range 22 kmS Tengchong, 1750 m, 24°49'29"N, 98°29'27"E, second. forest, litter, dead wood sifted, 2.VI.2007, leg. A. Pütz" (cPüt, cAss).
Description: 3.4-3.7 mm. External morphology as in H. capillaricornis, except as follows: Antennae with antennomeres I-II pale brown to dark brown and III-XI pale yellowish. Pronotum conspicuously glossy, without trace of microsculpture even near the margins ( Fig. 1). Abdomen with relatively sparse fine puncturation and with very shallow, barely noticeable microsculpture ( Fig. 2). : tergite and sternite VII large, with broadly and weakly convex posterior margins ( Figs 3-4); sternite VIII posteriorly with deep and proximally U-shaped excision; appendices of pleurites VIII each with one long seta ( Fig. 5); sclerites of segment IX as in Fig. 6; internal sac of aedeagus with longer row of numerous strongly sclerotised structures and with additional row of 8 slender spines ( Fig. 7). : tergite and sternite VII distinctly smaller than in ; posterior margin of tergite VII acute, that of sternite VII strongly convex ( Figs 8-9); segment VIII as in Fig. 10. Comparative notes: Based on the morphology of the primary and secondary sexual characters, the species refers to the H. capillaricornisspecies group, whose original distribution is confined to the Palaearctic region. From all other species of this group, H. splendensis distinguished by the sparser puncturation and the less distinct microsculpture of the abdomen, as well as by the distinctive internal structures of the internal sac and by the secondary sexual characters (shapes of male sternite VIII, as well as of female tergite and sternite VII). For illustrations of the sexual characters of other species of the H. capillaricornisgroup see ASSING & WUNDERLE (1995). The only other Habrocerusspeciesthat was previously known from Chinais H. schuelkei ASSING & WUNDERLE, 1996from Shaanxi. This species, however, refers to the H. schwarzispecies group and is characterised by sexual characters of completely different morphology; for illustrations see ASSING & WUNDERLE (1996).
Etymology: The name (Latin, present participle of splendere) refers to the glossy appearance of the species.
Distribution and bionomics: Thetype specimens were collected in two localities to the south of Tengchong( China: Yunnan province) by sifting the leaf litter of deciduous forests at altitudes of 1750 and 1900 m. The abdomen of a dissected female paratypecontained a conspicuous structure of unknown identity ( Fig. 11).
