Bifidocoelotes obscurus Zhou, Yuen & Zhang, 2017: 430, figs 1A–E, 2A–G.

Type material. Holotype male, and 9 male and 10 female paratypes from Hong Kong, China, deposited in the school of Life Science, Southwest University, China (SWUC), not examined.

Diagnosis. According to photos and drawings in Zhou et al. (2017), the female of this species is similar to that of B. elongatus sp. nov. in having a long and slightly bifurcated epigynal tooth which almost reaches the posterior margin of epigyne but can be distinguished by the different configuration of spermathecae and copulatory ducts: spermathecal heads mammiform, and copulatory ducts are hard to differentiate from spermathecae in B. obscurus, while spermathecal heads thumb-shaped, and copulatory ducts tending to twist around spermathecae in B. elongatus sp. nov. (compare Zhou et al. 2017: figs 1B, 2D with Fig. 3D). The male of this species is similar to those of B. tsoi Li & Blick, 2020 and B. mammiformis sp. nov. in having a bifid conductor (Fig. 2A, B, D) but the two branches of conductor in B. obscurus are slenderer and longer than those of B. tsoi (compare Zhou et al. 2017: figs 1D, E, 2F, G with Wan g et al. 2001: figs 3, 4), and separated further apart from each other than those of B. mammiformis (compare Zhou et al. 2017: figs 1D, E, 2F, G with Fig. 4D, E).

Distribution. Known only from the type locality in China (Hong Kong) (Fig. 7).
