Bioramix (Leipopleura) tiani sp. nov. (Figs 22, 184–185, 315) Description. Body black-brown, shining, antennae, palpi and tarsi brown, elytral surface with metallic sheen. Male (Figs 22, 184–185, 315). Head. Anterior margin of epistome straight, surface with dense and coarse punctures. Frons and genae weakly convex, surface with dense and coarse punctures. Dorsal surface of head with dense and coarse punctures. Eyes transverse, anterior margin shallowly emarginate. Antennae (Fig. 22: A) not reaching pronotal base, antennomeres II–VIII short cylindrical and thicker at apex, IX–X nearly spherical, XI sharped-oval. Length (width) ratio of antennomeres II–XI 22 (17): 40 (18): 24 (20): 24 (19): 23 (17): 23 (17): 21 (18): 22 (19): 24 (17): 31 (19). Prothorax. Pronotum (Fig. 22: B) transverse and weakly convex, 1.6 times as wide as long and 1.8 times as wide as head. Lateral sides widest at base, nearly straight narrowing toward apex. Ratio of width at anterior margin to basal 26: 39. Anterior margin weakly emarginate, posterior one weakly protruding backward. Anterior and posterior angles obtuse. Anterior and posterior margins edged laterally, entire lateral margins edged. Dorsal surface with sparse and fine punctures on disc, denser and coarser at sides. Lateral sides with pair of round depressions near disc. Prothoracic hypomera with longitudinal wrinkles and sparse yellow setae. Prosternum anterior to procoxae with yellow setae, prosternal process sharply sloping behind procoxae, apex not projecting beyond level of procoxae in lateral view. Pterothorax. Elytra elongate-oval and convex, 1.3 times as long as wide and 1.3 times as wide as pronotum, base wider than pronotum and widest at middle. Surface with sparse and fine punctures, fine wrinkles, traces of longitudinal carinae. Lateral margins of elytra not reaching sutural angle, interrupted at middle, visible at base in dorsal view. Abdomen with dense yellow setae, ventrites 1–2 depressed at middle. Legs. Profemora stout, with sparse punctures and yellow setae. Protibiae (Fig. 22: D) gradually widened toward apex, underside concave at apex, apical margin foliate extended, inner side with dense yellow hairbrush from middle to apex. Protarsi (Fig. 22: C) narrower than apex of protibiae. Meso- and metafemora longer than profemora. Mesotibiae (Fig. 22: E) gradually widened toward apex, with rufous thick setae, inner side with dense yellow hairbrush from middle to apex. Mesotarsi (Fig. 22: F) narrower than apex of mesotibiae. Metatibiae (Fig. 22: G) straight, with rufous thick setae, inner side with dense yellow hairbrush from middle to apex. Length (width) ratio of pro-, meso- and metafemora 17 (7): 16 (7): 19 (7), that of corresponding tibiae 18 (8): 21 (6): 22 (6), and protarsi 16 (23): 29 (46): 19 (45): 37 (10): 50 (20), mesotarsi 24 (27): 29 (40): 24 (36): 17 (27): 47 (20), metatarsi (Fig. 22: H) 68 (19): 38 (19): 33 (23): 51 (20). Aedeagus (Figs 22: I–J, 184–185) 2.9 mm long and 0.9 mm wide. Parameres 1.0 mm long and 0.8 mm wide, widest at base and narrowing toward apex, lateral sides weakly emarginate posterior to apex in dorsal view, “S” curved in lateral view. Measurements. Body length: ♂ 10.1–10.3 mm and width: ♂ 5.0– 5.1 mm. Type material. Holotype: ♂ (MHBU), CHINA : Xizang: between Sênggê Township and Lhozhag County, 4423 m, 19.VI.2010, Ming-Yi Tian leg. [SCAU]. Paratypes: 2♂♂ (MHBU), same data as holotype. Distribution. China: Xizang. Diagnosis. This new species is similar to Bioramix (Leipopleura) lhozhagensis sp. nov., but can be distinguished from the latter by the following characters (based on male): (1) pronotum widest at base, surface with finer punctures, lateral sides with pair of round depressions near disc (at middle, coarser, without in B. lhozhagensis); (2) lateral margins of elytra not reaching sutural angle (reaching in B. lhozhagensis). Etymology. This species name is derived from the family name of the collecter—Ming-Yi Tian.
