description: <i>Bioramix</i> (<i>Leipopleura</i>) <i>riwoqeica</i> sp. nov. (Figs 18, 170–171, 300–301, 384) <b>Description.</b> Body black, weakly shining, legs brown, elytral surface with metallic sheen. <b>Male</b> (Figs 18, 170–171, 300). <i>Head</i>. Anterior margin of epistome nearly 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. 18: 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): 37 (17): 23 (16): 20 (17): 23 (16): 24 (17): 30 (17): 25 (17): 25 (17): 24 (17). <i>Prothorax</i>. Pronotum (Fig. 18: B) transverse and convex, 1.6 times as wide as long and 2.0 times as wide as head. Lateral sides widest at base, arcuately narrowing toward apex. Ratio of width at anterior margin to basal 26: 44. Anterior margin weakly emarginate, posterior one straight. Anterior and posterior angles obtuse. Anterior and posterior margins edged laterally, entire lateral margins edged. Dorsal surface with sparse and fine punctures on disc, dense and coarse at sides. 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. <i>Pterothorax.</i> 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 and fine punctures, dense and coarse wrinkles. Lateral margins of elytra merging with outer margins of epipleura anterior to apex of elytra and reaching sutural angle, visible at base in dorsal view. <i>Abdomen</i> with dense yellow setae, ventrites 1–2 flattened at middle. <i>Legs.</i> Profemora stout, with sparse punctures and yellow setae. Protibiae (Fig. 18: D) gradually widened toward apex, underside concave at apex, apical margin weakly foliate extended, inner side with dense yellow hairbrush from middle to apex. Protarsi (Fig. 18: C) narrower than apex of protibiae. Meso- and metafemora longer than profemora. Mesotibiae (Fig. 18: E) gradually widened toward apex, with rufous thick setae, inner side with dense yellow hairbrush from middle to apex. Mesotarsi (Fig. 18: F) narrower than apex of mesotibiae. Metatibiae (Fig. 18: G) straight, with rufous thick setae, inner side with dense yellow hairbrush from middle to apex. Length (width) ratio of pro-, meso- and metafemora 20 (7): 22 (7): 28 (8), that of corresponding tibiae 19 (7): 19 (6): 27 (6), and protarsi 19 (25): 37 (60): 31 (54): 14 (34): 46 (15), mesotarsi 27 (31): 34 (53): 31 (46): 19 (26): 43 (17), metatarsi (Fig. 18: H) 66 (21): 39 (23): 29 (23): 58 (20). <i>Aedeagus</i> (Figs 18: I–J, 170–171) 2.2 mm long and 0.7 mm wide. Parameres 0.9 mm long and 0.6 mm wide, widest at base and nearly straight narrowing toward apex, lateral sides weakly emarginate posterior to apex in dorsal view, distal part weakly curved dorsally in lateral view. <b>Female</b> (Fig. 301). Abdominal ventrites 1–2 not flattened at middle, pro- and mesotarsi not widened, other characters similar to male. <b>Measurements.</b> Body length: &amp;male; 9.2–9.3 mm, &amp;female; 8.0 mm and width: &amp;male; 4.7–4.8 mm, &amp;female; 4.3 mm. <b>Type material.</b> <b>Holotype:</b> &amp;male; (MHBU), <b>CHINA</b> <b>:</b> <b>Xizang:</b> Ruduo Village, Samdo Town, Riwoqê County, 31°06.655′ N, 96°42.290′ E, 3755 m, 22.VIII.2018, Xing-Long Bai, Zi-Yuan Hu &amp; Ming-Min Ma leg. <b>Paratypes:</b> 5&amp;male;&amp;male; (MHBU), same data as holotype; 1&amp;male; (MHBU), Lieyong Shan, Samdo Town, Riwoqê County, 31°05.185′ N, 96°41.505′ E, 3890 m, 28.VII.2019, Guo-Dong Ren, Xing-Long Bai, Ya-Lin Li, Ming-Min Ma &amp; He Shi leg.; 1&amp;male;, 1&amp;female; (MHBU), Riwoqê County, 3900 m, 6.VII.2008, Guo-Dong Ren <i>et al</i>. leg.; 5&amp;male;&amp;male;, 3&amp;female;&amp;female; (MHBU), Yueluo Vil- lage, Riwoqê County, 31°24.420′ N, 96°27.205′ E, 3918 m, 27.VII.2019, Guo-Dong Ren, Xing-Long Bai, Ya-Lin Li, Ming-Min Ma &amp; He Shi leg. <b>Distribution.</b> China: Xizang. <b>Diagnosis.</b> This new species is similar to <i>Bioramix</i> (<i>Leipopleura</i>) <i>igori</i> Li &amp; Egorov, 2013, but can be distinguished from the latter by the following characters (based on male): (1) posterior margin of pronotum straight (protruding backward in <i>B. igori</i>); (2) metatibiae straight (curved in <i>B. igori</i>); (3) parameres wide, distal part weakly curved dorsally without a hook apically in lateral view (narrow, more strongly curved dorsally with a hook apically in <i>B. igori</i>). <b>Etymology.</b> This species name is derived from the type locality—Riwoqê.
