( Figs. 2–15 , 44–45 ) Type material. Holotype : male, CHINA : Tibet, Gongbujiangda, Songduo, 29º54' N , 92º29' E , 4259 m , 16 Aug. 2010 , Yun-chun Li and Yong-sheng Pan leg. (MCWNU). Paratype : 1 female , same data as the holotype (MCWNU). Diagnosis. The new species resembles Gnaptorina (Hesperoptorina) nigra Shi, Ren & Merkl, 2007 , with the following differences: Genal margin parallel before eyes. Prosternum in front of procoxae gently sloping. Maximum of width of elytra before middle. More than anterior 1/2 of outer margin of epipleura visible from above. Parameres with outer margins regularly narrowing toward apex. Etymology. This new species is named in honour of Gleb S. Medvedev, a prominent expert of Tenebrionidae , leader of the Laboratory of Insect Systematics of the Zoological Institute, Russian Academy of Sciences, St. Petersburg. Description. Body black, weakly shining. Male ( Figs 2, 4–12 ). Anterior margin of clypeus straight. Lateral margin of head with obtuse-angled shallow incision above antennal base. Genal margin parallel before eyes. Eyes slightly protruding beyond contour of head. Vertex slightly convex, with dense punctures. Frontoclypeal suture indistinct. Antennae ( Fig. 2 ) short, reaching posterior 1/4 of pronotum when posteriorly extended. Length (width) ratio of antennomeres 2 to 11 as follows: 11(9): 19(9): 11(9): 11(9): 11(9): 11(9): 11(12): 11(12): 12(13): 18(14). Pronotum ( Fig. 4 ) transverse, 1.25 times as wide as long, maximum width before middle, 1.71 times as wide as head. Ratio of pronotal width at anterior margin to its maximum width and width at base 0.55: 1.00: 0.88. Lateral margins of pronotum more sharply arcuately narrowing to anterior margin than to base, shallowly sinuate before base, entirely bordered. Anterior margin of pronotum nearly straight, bordered laterally; base straight, not bordered. Anterior angles of pronotum obtuse, rounded apically; posterior ones weakly obtuse. Pronotal surface between lateral margins convex, with dense punctures fine at disc center and larger laterally, median depression shallow and short. Propleura concave, with longitudinal wrinkles and granules. Prosternum in front of procoxae gently sloping. Intercoxal process with shallow median depression, gently sloping behind procoxae.

More than anterior 1/2 of outer margin of epipleura visible from above. Elytral surface between epipleura and sutural margin convex, with shallow fine punctures and irregular short wrinkles. Epipleural surface smooth, with fine wrinkles. Abdominal ventrites with punctures and brown setae. Legs ( Figs 5–7 ) moderately robust, length (width) ratio of pro-, meso- and metafemora 77(25): 90(22): 100(24); tibiae: 69(11): 72(14): 92(16). Protibiae with massive upper spur at apical margin; lower spur very fine and pointed. Only protarsomere 1 with tuft of light setae at apical margin of plantar surface. Metatibiae weakly incurved, gradually widening towards apex. Length (width) ratio of metatarsomeres 1 to 4 as follows: 16(6.0): 10(5.0): 9(5.0): 20(5.5). Aedeagus ( Figs 8–10 ): length 1.77 mm , width 0.57 mm . Parameres 0.65 mm long and 0.42 mm wide, with outer margins regularly narrowing towards apex. Spiculum gastrale as in Fig. 11 . Apical margin of abdominal sternite 8 sinuate ( Fig. 12 ). Female ( Figs 3, 13–15 ). Body wider. Antennae ( Fig. 3 ) shorter than in male. Pronotum 1.33 times as wide as long. Elytra 1.38 times as long as wide. Anterior 1/3 of outer margin of epipleura visible from above. Upper spur of protibiae moderately massive and rounded apically; lower spur missing. Plantar surface of protarsomeres without apical tuft of pale hairs. Ovipositor as in Figs 13–14 . Spiculum ventrale as in Fig.15 . Measurements. Male body length 9.0 mm, width 4.4 mm ; female body length 9.1 mm , width 4.6 mm . Distribution. China : Tibet (Gongbujiangda, Songduo).
