Descriptive notes.

Male. Aedeagus: basal piece distinctly longer than dorsal plate of each paramere (Fig. 4D-F ); ventral process of each paramere nearly straight, feebly bent inwards in ventral view (Fig. 4D ) and vertical in lateral view (Fig. 4F ); dorsal plates of parameres feebly longer than ventral processes (Fig. 4D, F ), with outer margin obviously abruptly converging apically, apical margins truncate in dorsal view (Fig. 4E ); laterophyse slightly shorter than ventral process, with apices acute and appreciably directing dorso-inwards (Fig. 4F ).

Female. Internal organ of reproductive system (Fig. 12A ): spermatheca nearly as long as diverticulum; accessory gland ~ 2.5 × longer than spermatheca.

Abdominal sternite VIII (Fig. 16A ): triangular emargination in middle and narrowly rounded emarginations on both sides of posterior margin, lateral emarginations obviously deeper and feebly wider than the middle one, the portions between lateral and middle emarginations moderately wide and right-angled at apices, obviously extending over apices of latero-apical angles, which are narrowly rounded.

Distribution.

China (Hubei, Shaanxi).

Remarks.

The aedeagus of this species was illustrated only in ventral and lateral views by Švihla (2004). Here, the aedeagus is illustrated in ventral, dorsal, and lateral views, and the abdominal sternite VIII and internal genitalia of the female are illustrated for the first time. Additionally, the distribution range of this species is expanded, with geographic records added from Shaanxi Province.
