Descriptive notes.

Male. Aedeagus: basal piece slightly longer than dorsal plate of each paramere (Fig. 5D-F ); ventral process of each paramere slender and slightly expanded at apices, nearly straightly and approaching to each other in ventral view (Fig. 5D ), inclining ventrally in lateral view (Fig. 5F ); dorsal plates of parameres feebly longer than ventral process (Fig. 5D, F ), with inner margins feebly emarginate at inner apical angles, outer margins slightly converging apically in dorsal view (Fig. 5E ); laterophyse slightly longer than ventral process, with apices acute and appreciably directing dorso-outwards (Fig. 5F ).

Female. Internal organ of reproductive system (Fig. 14B ): spermatheca slightly longer than diverticulum; accessory gland slightly longer than spermatheca.

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

Distribution.

China (Sichuan).

Remarks.

Only the apical parts of the aedeagus of this species was illustrated by Švihla (2004). In this work, the aedeagus is illustrated in general views, and the abdominal sternite VIII and internal genitalia of the female are illustrated for the first time.
