description: <i>Bioramix</i> (<i>Leipopleura</i>) <i>miranda</i> sp. nov. (Figs 15, 96–97, 256–257) <b>Description.</b> Body black, weakly shining. <b>Male</b> (Figs 15, 96–97, 256). <i>Head</i>. Anterior margin of epistome straight, surface with dense and coarse punctures. Frons flattened, 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. 15: A) 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 18 (15): 30 (17): 26 (15): 20 (16): 23 (16): 26 (15): 28 (18): 25 (18): 24 (18): 33 (17). <i>Prothorax</i>. Pronotum (Fig. 15: 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 21: 36. Anterior margin slightly emarginate or straight, posterior one straight. Anterior angles obtuse, posterior ones rectangular. Anterior and posterior margins edged laterally, entire lateral margins edged. Dorsal surface with moderately dense and coarse punctures on disc, dense 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, 1.2 times as long as wide and 1.1 times as wide as pronotum, base as wide as pronotum and widest at middle. Surface with shallowly sparse and fine punctures, shallowly 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. <i>Abdomen</i> with dense yellow setae, ventrites 1–2 depressed at middle. <i>Legs.</i> Profemora stout, with sparse punctures and yellow setae. Protibiae (Fig. 15: 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. 15: C) as wide as apex of protibiae. Meso- and metafemora longer than profemora. Mesotibiae (Fig. 15: E) gradually widened toward apex, with rufous thick setae, inner side with dense yellow hairbrush from middle to apex. Mesotarsi (Fig. 15: F) slightly narrower than apex of mesotibiae. Metatibiae (Fig. 15: G) straight, with rufous thick setae, inner side with dense yellow hairbrush from middle to apex. Length (width) ratio of pro-, meso- and metafemora 18 (5): 20 (6): 25 (6), that of corresponding tibiae 16 (5): 16 (5): 25 (5), and protarsi 20 (21): 32 (51): 29 (50): 15 (31): 34 (16), mesotarsi 30 (30): 32 (47): 25 (41): 17 (25): 52 (17), metatarsi (Fig. 15: H) 59 (21): 38 (21): 18 (20): 46 (19). <i>Aedeagus</i> (Figs 15: I–J, 96–97) 2.7 mm long and 0.7 mm wide. Parameres 0.9 mm long and 0.5 mm wide, widest at base and narrowing toward apex, lateral sides emarginate posterior to apex in dorsal view, distal part strongly widened, nearly as wide as base, curved dorsally in lateral view. <b>Female</b> (Fig. 257). 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. <b>Measurements.</b> Body length: &amp;male; 7.7–8.3 mm, &amp;female; 8.1–8.8 mm and width: &amp;male; 3.9–4.4 mm, &amp;female; 4.2–4.7 mm. <b>Type material.</b> <b>Holotype:</b> &amp;male; (MHBU), <b>CHINA</b> <b>:</b> <b>Qinghai:</b> Zadoi County, 4400 m, 4.VII.2008, Guo-Dong Ren <i>et al</i>. leg. <b>Paratypes:</b> 1&amp;male;, 1&amp;female; (MHBU), same data as holotype; 2&amp;female;&amp;female; (IZCAS), Zhidoi County, 14.VI.1979, Ze-Bin Lin leg.; 1&amp;female; (MHBU), Shanglaxiu Township, Yushu County, 32°57.479′ N, 96°06.856′ E, 4227 m, 21.VII.2012, Guo-Dong Ren <i>et al</i>. leg. <b>Distribution.</b> China: Qinghai. <b>Diagnosis.</b> This new species is similar to <i>Bioramix</i> (<i>Leipopleura</i>) <i>laxipenis</i> sp. nov. (see diagnosis of <i>B. laxipenis</i>). <b>Etymology.</b> This species name is derived from its bizarre parameres in the subgenus.
