Length, male 4.5-4.6 mm, female 4.7-4.8 mm.

General color yellowish.

Male ventral abdominal apodemes reaching segment 4 (Fig. 14). Male pygofer with dorsoposterior margin strongly sinuate (Fig. 13); ventral appendage expanded at distal 2/3, thereafter abruptly tapering to spine-like apex (Figs 13, 16). Subgential plate abruptly expanded laterobasally about twice as broad basally than distally; with 11 lateral macrosetae in basal group, an oblique line of 17 macrosetae and several long fine setae subbasally to apex and ca.35 short microsetae at outer margin (Fig. 17). Paramere as in Fig. 18. Aedeagus shaft very long and narrow, cylindrical, nearly straight in lateral view, with a subapical trifurcate process on each side, branches slender (Figs 19, 20). Anal tube process relatively long (Fig. 21).

Type materials.

Holotype male. China: Beipei, Chongqing, 6 May 2008, coll. Zaihua Yang. Paratypes, 13♂♂, 5♀♀, same data as holotype (GUGC and 1♂, 1♀ in BMNH).

Etymology.

The new speciesnamealludes to the trifurcate processes of the aedeagus.

Thenew species can be distinguished mainly by the strongly sinuate posterior margin of the pygofer and shape of the aedeagal shaft and configuration of its process as noted in the description.
