Diagnosis. This species is similar to B. cinerascens (Doleschall, 1859) (judged from the figures of Benjamin et al. 2008), but can be separated by the flat or slightly concaved dorsal cymbium (convex in B. cinerascens ) and flat, not posteriorly folded bulb (with a fold posteriorly in B. cinerascens ).

Description. Male: See Song, 1993.

Palp ( Figs 12 A–D, 14 A–B). Palp with a short RTA; the dorsal cymbium slightly concave, with trim scopulae; tegulum with a ear-shaped median apophysis; embolus twisted, helix-shaped distally; conductor translucent.

Female (IZCAS, Tang_No. 82, described for the first time): Total length 9.10. Prosoma 4.50 long, 4.00 wide; Opisthosoma 4.90 long, 3.50 wide. Body flat with clavate hairs. Prosoma blackish brown, 2 clavate hairs mounted between AME. Clypeus with clavate hairs. Eye measurements: AME 0.14; ALE 0.18; PME 0.16; PLE 0.16; AME–AME 0.20; AME–ALE 0.16; PME–PME 0.26; PME–PLE 0.42. MOA length 0.56 with front width 0.48 and back width 0.56. Chelicera, gnathecoxa, labium brown, chelicerae with 4 pro- and 5 retromarginal teeth including a vestige tooth, with about 8 small denticles between teeth. Sternum yellowish brown. Femur I swollen medially, bears 3 short spines with large base. Tibiae I with 5 prolateral, 4 retrolateral thick spines, metatarsi I with 3 prolateral and 3 retrolateral spines. Leg formula: I, IV, III, II; leg measurements: I: 13.00 (4.30, 5.60, 2.10, 1.00); II: 7.60 (2.60, 2.80, 1.40, 0.80); III: 8.30 (2.60, 3.00, 1.80, 0.90); IV: 8.60 (3.20, 2.80, 1.80, 0.80). Opithosoma grayish black with black spots. Dorsum with clavate hairs.

Epigynum ( Figs 13 C–D, 14 C–D). Epigynum with an anteriorly situated hood; median septum long, connected with hood; epigynal teeth paired, short, arising bilaterally; copulatory ducts thick, twisted; spermathecae convoluted, narrower than copulatory ducts; a pair of wrinkled chitinous lamellae covered the posterior part of spermathecae.

Distribution. China (Hainan, Yunnan).

Variations. Total length: male 6.00–6.80 (n=8); female: 8.20–9.50 (n=3).

Remark. The male of this species was first described by Song (1993). The female was then described by Song (1994), but unfortunately it was not correctly matched. The female specimen (Song 1994) was not found in IZCAS collection now. We identified B. hainanus with both sexes from a large sample of specimens collected from Hainan.
