Material examined.

1 female (holotype, HNU): China, Hunan Province, Chenbu County, 1982, Y. Liu leg.

Diagnosis.

Female resembles B. yuelu sp. nov. in having atrium similar and conspicuous epigynal teeth (Fig. 6 ; Zhao et al. 2023: fig. 7A-C) but distinguished by the following: spermathecae highly convoluted (Fig. 3B ) vs round in B. yuelu sp. nov. (Fig. 6C ); copulatory ducts with two turns (Fig. 3B ) vs with one turn in B. yuelu sp. nov. (Fig. 6C ).

Description (partial).

Epigyne (Fig. 3A, B ): atrium glasses-shaped, occupying 1/3 of epigyne; epigynal hood located laterally; epigynal teeth distinct; copulatory opening located mid-centrally; copulatory ducts originating centrally, sinuous; spermathecae fist-shaped; fertilization ducts transparent. Habitus as shown by Wang et al. (1996).

Male unknown.

Distribution.

China (Hunan) (Fig. 7 ).
