Remarks. Males of this species can be easily separated from those of all other congeners by a combination of the following characters: antennomeres XI enlarged, with a protuberance near the base ( Fig. 7 B, 7C); protibiae with small apical protuberance; mesotibiae with small apical spur; abdominal sternite VII with apical lamina ( Fig. 7 F) transverse, pointed at apex of lateral margin. This species was described from Wolong Nature Reserve, and here we record it also from eastern Daba Shan, Micang Shan, Liping Forest Park and Qingcheng Shan. Illustrations of the sternite VII ( Figs 7 F, 8A–C) and the aedeagus ( Figs 7 G, 8D–F) found for each population are provided here. Distribution. Southwest China : Chongqing and Sichuan, Northwestern China : Shaanxi. ( new provincial record ).
