Diagnosis. Brachytrycherus curviantennae is similar to B. humeralis and B. denticulatus sp. nov. in both bodies being broadly oval, elytral maculae transverse, pronotum sides strongly curved. However, antennomere 3 distinctly curved outwards and elytral maculae nearly cymbiform can distinguish B. curviantennae from all its congeners. Length. 8.5-9.4 mm; width: 5.1-5.2 mm. Type material. Holotype, male, Xizang, Medog, 1500 m, 20.VIII.2013, Wen-Xuan Bi leg. (SHEM). Paratypes, 1 female, Xizang, Medgo, Beibeng, Gelincun, 3.VIII.2014, Wen-Xuan Bi leg. (MHBU); 1 female, Xizang, Medgo, Beibeng, Gelincun, 3.VIII.2014, Wen-Xuan Bi leg. (CBWX). Type locality. China (Xizang). Distribution. China (Xizang). Biology and ecology. The male was hand collected by simple searching, as it is active on branches at night ( Fig. 16C ). Two females were collected by shaking the tree from a large clump of dead wood of Fagaceae plants ( Fig. 16A ) ( Chang et al. 2016 ). Figure 15. Type specimens of B. curviantennae .
