Remarks. Males of this species can be easily separated from those of all other congeners by a combination of the following characters: antennomere XI enlarged; protibiae with distinct apical projection; abdominal sternite VII with apical lamina ( Fig. 14 E) widest near basal third and narrowed apically. This species was described from Tianmu Shan, and here we record it also from Baishanzu, Fengyang Shan, Longwang Shan, and Wuyi Shan. Illustrations of the sternite VII ( Figs 14 E, 15A–C) and the aedeagus ( Figs 14 F, 15D–F) found in each population are provided here.

Distribution. Eastern China: Zhejiang, Fujian. (new provincial record).
