Descriptive notes.

Male. Aedeagus: basal piece distinctly longer than dorsal plate of each paramere (Fig. 4A-C ); ventral process of each paramere short and thin, nearly straight and approaching to each other in ventral view (Fig. 4A ), slightly bent dorsally in lateral view (Fig. 4C ); dorsal plates of parameres as long as ventral process (Fig. 4B, C ), with outer margins abruptly converging apically, apical margins subrounded in dorsal view (Fig. 4B ); laterophyse feebly shorter than ventral process, with apices acute and markedly directing dorso-outwards (Fig. 4C ).

Female. Internal organ of reproductive system (Fig. 12D ): spermatheca nearly as long as diverticulum; accessory gland ~ 3.0 × longer than spermatheca.

Abdominal sternite VIII (Fig. 16D ): triangular emargination in middle and subrounded emarginations on both sides of posterior margin, lateral emarginations slightly deeper and obviously wider than the middle one, the portions between lateral and middle emarginations narrow and acute at apices, obviously extending over apices of latero-apical angles, which are widely triangular.

Distribution.

China (Fujian).

Remarks.

The aedeagus, abdominal sternite VIII, and internal genitalia of female are illustrated for the first time for this species herein.
