Material examined.

1♂, CHINA, Yunnan, Mengla County, Menglun Town, Xishuangbanna Nature Reserve: nearby fish pond (21°57.883'N, 101°12.147'E, 839 m), ravine rainforest, 15 August 2011, Q. Zhao & Z. Chen leg.; 1♀, CHINA, Yunnan, Mengla County, Xiaolongha Village, Xishuangbanna Nature Reserve: Biological diversity corridor (21°24.265'N, 101°37.300'E, 653 m), seasonal rainforest, 27 June 2012, Q. Zhao & Z. Chen leg.

Diagnosis.

Differs from the closely related Bavia aericeps Simon, 1877 (see Żabka 1988: figs 29-36) by the tibia with a distinct dorsal apophysis (Fig. 5B) and serrated embolus (Fig. 5D). The females differ from Bavia aericeps by the horizontal position of the copulatory openings (Fig. 6A) vs. the inclined copulatory organs and the arc-shaped posterior epigynal margin (Fig. 6A) vs. triangular.
