Comments. Males of this species can be easily separated from those of all other congeners by a combination of the following characters: antennomeres XI with a distinct disc-like protuberance near middle; abdominal sternite VII with apical lamina (Fig. 3 D) composed of two sclerites, right one widest near base, gradually narrowing toward apex. This species was previously described from the Xiling Mt., here we report it also from the Er’lang Shan and Qingcheng Shan. Illustrations of sternite VII (Figs 3 D, 4A, 4B) and the aedeagus (Figs 3 E, 4C, 4D) of each population are provided here.

Distribution. Southwest China: Sichuan.
