Aedeagus moderately swollen laterally near middle (Fig. 2A, B); ventral processes of parameres abruptly and strongly thinned apically near bases, approaching to each other in ventral view (Fig. 2A), hooked and acute at apices, bent ventrally in lateral view (Fig. 2C); conjoint dorsal plate of parameres obviously longer than ventral processes (Fig. 2A, C), with apical margin roundly and deeply emarginate in middle, lateral margins feebly diverging apically, latero-apical angles rounded in dorsal view (Fig. 2B), and strongly inclined ventrally in lateral view (Fig. 2C); the emargination between conjoint dorsal plate and ventral process about half length of aedeagus (Fig. 2C). Female. Internal organ of reproductive system (Fig. 3A): vagina stout and abruptly thinned at ventroapical portion into a short tube, where diverticulum and spermathecal duct arising separately; diverticulum short and spiral, evenly thin along the whole length; spermathecal duct short and nearly as long as the apical tube of vagina; spermatheca provided with a spiral tube, progressively thinned apically and nearly as long as diverticulum; accessory gland extremely long, about five times as long as spermatheca. Abdominal sternite VIII (Fig. 4A) strongly narrowed posteriorly, almost straight at posterior margin, with latero-apical angles widely rounded. Destribution (Fig. 35). China (Sichuan). Remarks. The aedeagus of this species was illustrated only in ventral and lateral views by Wittmer (1989). In this study, we present the first illustrations and descriptions of the female reproductive system and abdominal sternite VIII, as well as the aedeagus in lateral view for this species.
