Descriptive notes.

Male. Aedeagus: basal piece feebly longer than dorsal plate of each paramere (Fig. 6A-C); ventral process of each paramere stout and obviously bent inwards apically in ventral view (Fig. 6A), inclining ventrally in lateral view (Fig. 5C); dorsal plates of parameres obviously longer than ventral processes (Fig. 5A, C), with apical margins rounded (Fig. 5B); laterophyse feebly longer than ventral process, with apices acute and directing dorso-outwards (Fig. 5A, C).

Female. Internal organ of reproductive system (Fig. 13A): spermatheca feebly longer than diverticulum; accessory gland nearly as long as spermatheca.

Abdominal sternite VIII (Fig. 17A): triangular emarginations in middle and on both sides of posterior margin, lateral emarginations obviously deeper and wider than the middle one, the portion between lateral and middle emarginations wide and right-angled at apices, obviously extending over apices of latero-apical angles, which are narrowly rounded.

Distribution.

China (Jiangsu, Shanghai, Jiangxi, Hubei).

Remarks.

The aedeagus of this species was illustrated only in ventral and lateral views by Wittmer (1995). Herein, the aedeagus is illustrated in ventral, dorsal, and lateral views, and the female internal genitalia is illustrated for the first time.
