Descriptive notes.

Male. Aedeagus: basal piece slightly longer than dorsal plate of each paramere (Fig. 3D-F ); ventral process of each paramere thin and straight, approaching to each other in ventral view (Fig. 3D ) and inclining ventrally in lateral view (Fig. 3F ); dorsal plates of parameres slightly longer than ventral processes (Fig. 3D, F ), with inner margins abruptly diverging near middle, apical margins slightly arcuate and descending outwards in dorsal view (Fig. 3E ); laterophyse feebly longer than ventral process, with apices acute and directing dorso-outwards (Fig. 3D, F ).

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

Abdominal sternite VIII (Fig. 16B ): rounded emargination in middle and triangular emarginations on both sides of posterior margin, lateral emarginations obviously deeper than and nearly as wide as 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 triangular.

Distribution.

China (Shaanxi, Hubei, Sichuan, Gansu).

Remarks.

Li et al. (2015) provided an illustration of female internal genitalia for L. centrochinensis , which is of an unknown species. Additionally, the distribution range of this species is expanded, with geographic records added from Sichuan and Gansu provinces.
