Type material. Holotype male, China: Hainan Province, Qiongzhong County (19°03'N, 109°50'E), Diaoluoshan National Natural Reserve, 5 June 2009, Chao Zhang leg.

Etymology. The species name refers to the type locality.

Diagnosis. The new species strongly resembles B. maogan Tong & Li, 2009 , but can be distinguished by the marks on the carapace and the chelicerae without a pair of frontal curved apophyses ( Figs 4 B–D).

Description. Male (holotype). Total length 1.51 (1.60 with clypeus), carapace length 0.60, width 0.70. Leg I: 11.14 (2.90 + 0.14 + 2.73 + 4.73 + 0.64), tibia II lost, tibia III: 1.91, tibia IV: 2.55; tibia I L/d: 30. Habitus as in Fig. 4 A, carapace pale ochre-yellow with brown margins laterally; abdomen ochre-grey, with four pairs of irregular spots dorsally. Ocular area not elevated, thoracic furrow absent. Clypeus brown, unmodified. Sternum nearly as long as wide (0.47). Chelicerae as in Fig. 4 B, with pair of proximal rounded projections laterally and pair of short frontal apophyses. Retrolateral trichobothrium of tibia I at 15%; legs yellowish without spines and curved hairs, with vertical hairs proximally on all metatarsi; tarsus I with 18 pseudosegments, quite distinct distally. Palps as in Figs 4 C–D, trochanter with short rounded retrolateral apophysis and ventral apophysis; femur with small hump proximo-dorsally; procursus complicated distally, with ventral membranous flap and straight dorsal spine; bulb with complicated embolus and hooked apophysis, and hooked apophysis with a branch medially.
