Type material: Holotype male, 1 male paratype, CHINA: Sichuan, Luding County (29.8°N, 102.1°E), the road from Moxi Town to Yajiageng, 10 October 2005, Xiang Xu and Xiufeng Zhang leg. ( IZCAS)

Etymology. The species name is a compound word of the Latin noun venter and the Latin adjective furcatus, meaning “venter” and “forked” respectively, and referring to the shape of the conductor; adjective.

Diagnosis. This species is similar to D. calcariformis (Wang 1994) in having a bifid conductor and a small median apophysis, but can be distinguished by the presence of two patellar apophyses, the hooked lateral tibial apophysis and the different shape of conductor.

Description. Holotype male. Total length 7.7, prosoma 4.1 long, 2.6 wide; opisthosoma 3.6 long, 2.2 wide.
