description: <i>Bioramix</i> (<i>Leipopleura</i>) <i>seidlitzi</i> sp. nov. (Figs 20, 180–181, 311–312, 367) <b>Description.</b> Body black-brown, weakly shining, antennae, palpi and tarsi brown. <b>Male</b> (Figs 20, 180–181, 311). <i>Head</i>. Anterior margin of epistome protruding forward, surface with dense and coarse punctures. Frons and genae weakly convex, surface with dense and coarse punctures. Dorsal surface of head flattened, with dense and coarse punctures. Eyes transverse, anterior margin shallowly emarginate. Antennae (Fig. 20: 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): 38 (18): 25 (18): 25 (18): 25 (17): 24 (17): 28 (23): 24 (23): 23 (23): 31 (20). <i>Prothorax</i>. Pronotum (Fig. 20: B) transverse and convex, 1.6 times as wide as long and 1.8 times as wide as head. Lateral sides widest at middle, arcuately narrowing toward base and apex. Ratio of width at anterior margin to widest part and base 25: 42: 39. Anterior margin weakly emarginate or nearly straight, posterior one nearly straight, weakly emarginate laterally. Anterior angles obtuse, rounded apically, posterior ones 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 widely flattened from base to middle, with sparse and long setae along lateral margins. 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 sharped-oval and strongly convex, 1.2 times as long as wide and 1.2 times as wide as pronotum, base wider than pronotum and widest at middle. Surface with shallowly sparse, fine punctures and wrinkles, erected and long setae along lateral margins. Lateral margins of elytra not reaching sutural angle, interrupted anterior to middle, 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. 20: 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. 20: C) narrower than apex of protibiae. Meso- and metafemora longer than profemora. Mesotibiae (Fig. 20: E) gradually widened toward apex, with rufous thick setae, inner side with dense yellow hairbrush from middle to apex. Mesotarsi (Fig. 20: F) narrower than apex of mesotibiae. Metatibiae (Fig. 20: G) curved, with rufous thick setae, inner side with dense yellow hairbrush from middle to apex. Length (width) ratio of pro-, meso- and metafemora 20 (7): 23 (7): 28 (7), that of corresponding tibiae 20 (8): 20 (6): 28 (6), and protarsi 24 (21): 30 (49): 21 (50): 10 (36): 40 (17), mesotarsi 32 (24): 29 (35): 21 (34): 15 (21): 50 (17), metatarsi (Fig. 20: H) 70 (21): 39 (19): 30 (17): 48 (18). <i>Aedeagus</i> (Figs 20: I–J, 180–181) 2.9 mm long and 0.8 mm wide. Parameres 1.0 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 strongly curved dorsally in lateral view. <b>Female</b> (Fig. 312). Body wider, 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; 9.3–9.4 mm, &amp;female; 8.6–9.3 mm and width: &amp;male; 4.3–5.1 mm, &amp;female; 4.6–5.1 mm. <b>Type material.</b> <b>Holotype:</b> &amp;male; (MHBU), <b>CHINA</b> <b>:</b> <b>Xizang:</b> Yiqing Township, Baxoi County, 30°29.297′ N, 97°09.468′ E, 4333 m, 10.VIII.2016, Xiu-Min Li, Xing-Long Bai, Run-Yang Zhang &amp; Xian-Lei Shao leg. <b>Paratypes:</b> 6&amp;male;&amp;male;, 6&amp;female;&amp;female; (MHBU), same data as holotype; 14&amp;male;&amp;male;, 17&amp;female;&amp;female; (MHBU), Yiqing Township, Baxoi County, 30°41.452′ N, 96°59.469′ E, 4340 m, 10.VIII.2015, Guo-Dong Ren, Xing-Long Bai &amp; Jun-Sheng Shan leg.; 2&amp;female;&amp;female; (MHBU), Ra’og Town, Baxoi County, 29.3687° N, 96.9171° E, 4500 m, 25.VII.2009, Guo-Dong Ren, Yi-Bin Ba &amp; Yong Zhou leg.; 1&amp;male; (MHBU), Bangda Town, Baxoi County, 30°22.172′ N, 97°14.014′ E, 4184 m, 10.VIII.2015, Guo-Dong Ren, Xing-Long Bai &amp; Jun-Sheng Shan leg.; 1&amp;female; (MHBU), Ranni Village, Têmtog Town, Zogang Coun- ty, 1.VI.2017, Guang-Lin Xie leg. [YUJC]. <b>Distribution.</b> China: Xizang. <b>Diagnosis.</b> This new species is similar to <i>Bioramix</i> (<i>Leipopleura</i>) <i>reinigi</i> (Kaszab, 1940), but can be distinguished from the latter by the following characters (based on male): (1) lateral sides of pronotum widely flattened from base to middle, posterior angles obtuse (narrowly depressed, rectangular or weakly obtuse in <i>B. reinigi</i>); (2) elytra with erected and long setae along lateral margins (recumbent and short in <i>B. reinigi</i>); (3) apex of parameres wider, distal part almost not curved ventrally in lateral view (narrower, strongly curved ventrally in <i>B. reinigi</i>). <b>Etymology.</b> This species is named in honor of Georg von Seidlitz (1840–1917), who made a great contribution to the study of Palaearctic Tenebrionidae.
