Bioramix (Leipopleura) homoplasta sp. nov.
( Figs 9 View FIGURES 9–10 , 74–75 View FIGURES 74–97 , 234–235 View FIGURES 232–237 )
Description. Body black, weakly shining.
Male ( Figs 9 View FIGURES 9–10 , 74–75 View FIGURES 74–97 , 234 View FIGURES 232–237 ). Head. Anterior margin of epistome straight, surface with dense and coarse punctures. Frons flattened 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. 9 View FIGURES 9–10 : A) almost 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 17 (13): 24 (15): 19 (14): 20 (15): 22 (14): 20 (14): 25 (18): 23 (19): 22 (22): 31 (20).
Prothorax. Pronotum ( Fig. 9 View FIGURES 9–10 : B) transverse and convex, 1.5 times as wide as long and 2.0 times as wide as head. Lateral sides widest at base, nearly straight narrowing toward apex. Ratio of width at anterior margin to basal 20: 36. Anterior margin weakly emarginate, posterior one nearly straight. Anterior angles obtuse, posterior ones rectangular. Anterior and posterior margins edged laterally, entire lateral margins edged. Dorsal surface with dense and coarse punctures. Lateral sides narrowly depressed at middle. 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 1.1 times as wide as pronotum, base slightly wider than pronotum and widest at middle. Surface with shallowly sparse, fine punctures and dense wrinkles. Lateral margins of elytra merging with outer margins of epipleura anterior to apex of elytra and reaching sutural angle, visible at middle in dorsal view.
Abdomen with dense yellow setae, ventrites 1–2 weakly depressed at middle.
Legs. Profemora stout, with sparse punctures and yellow setae. Protibiae ( Fig. 9 View FIGURES 9–10 : D) gradually widened toward apex, underside concave at apex, inner side and outside margins straight, inner side with dense yellow hairbrush from middle to apex. Protarsi ( Fig. 9 View FIGURES 9–10 : C) narrower than apex of protibiae. Meso- and metafemora longer than profemora. Mesotibiae ( Fig. 9 View FIGURES 9–10 : E) gradually widened toward apex, with rufous thick setae, inner side with dense yellow hairbrush from middle to apex. Mesotarsi ( Fig. 9 View FIGURES 9–10 : F) nearly as wide as protarsi, narrower than apex of mesotibiae. Metatibiae ( Fig. 9 View FIGURES 9–10 : G) weakly curved, with rufous thick setae, inner side with dense yellow hairbrush from middle to apex. Length (width) ratio of pro-, meso- and metafemora 18 (6): 19 (6): 23 (7), that of corresponding tibiae 16 (6): 18 (5): 26 (5), and protarsi 18 (26): 34 (51): 22 (49): 12 (28): 51 (16), mesotarsi 26 (29): 30 (44): 22 (39): 15 (24): 41 (17), metatarsi ( Fig. 9 View FIGURES 9–10 : H) 71 (21): 36 (19): 28 (17): 50 (16).
Aedeagus ( Figs 9 View FIGURES 9–10 : I–J, 74–75) 2.2 mm long and 0.6 mm wide. Parameres 0.9 mm long and 0.5 mm wide, widest at base and narrowing toward apex, lateral sides slightly emarginate posterior to apex in dorsal view, distal part straight in lateral view.
Female ( Fig. 235 View FIGURES 232–237 ). Body wider, antennae not reaching pronotal base, abdominal ventrites 1–2 neither depressed nor flattened at middle, pro- and mesotarsi not widened, other characters similar to male.

Distribution. China: Qinghai.
Diagnosis. This new species is similar to Bioramix (Leipopleura) latitarsis sp. nov., but can be distinguished from the latter by the following characters (based on male): (1) lateral margins of elytra reaching sutural angle (not reaching in B. latitarsis ); (2) distal part of parameres straight in lateral view (parameres “S” curved in B. latitarsis ).
Etymology. This species name is derived from its similarity to B. latitarsis .
