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 ).
