Figs 4–6, 30–34

Type material: Holotype male, 1 male and 7 females paratypes, CHINA: Hainan Province, Dongfang City, Donghe Town, Nanlang Village, E´xian Cave (19°00.426´N, 109°05.345´E), 29 March 2005, Y. Song, X. Han, Y. Tong and G. Deng leg.

Etymology: The specific name is a noun in apposition, taken from the type locality.

Diagnosis: The new species is similar to B. gedeh Huber, 2005, but can be distinguished by the shapes of procursus, the narrowly separated cheliceral apophyses and the position of female epigynal pocket.

Description: Male (holotype). Total length 1.26 (1.36 with clypeus), carapace width 0.56. Leg 1: 8.33 (2.02+0.22+2.13+2.87+1.09), tibia 2: 1.48, tibia 3: 0.98, tibia 4: 1.36; tibia 1 L/d: 35. Habitus as in figs 4 and 5. Whole body yellowish white; carapace and opisthosoma both without marks. Ocular area not elevated, thoracic furrow absent; distance PME-PME 0.11; diameter PME 0.04; distance PME-ALE 0.01; AME absent. Clypeus unmodified. Sternum slightly wider than long (0.41/0.35). Chelicerae as in fig. 32, with pair of curved apophyses, tips 0.24 apart. Palps as in figs 30 and 31; trochanter with short retrolateral apophysis, femur with indistinct hump proximo-dorsally, procursus complicated distally, with ventral membranous flap, bulb with hooked apophysis and simple embolus. Retrolateral trichobothrium of tibia 1 at 30%; legs without spines, vertical hairs, and curved hairs; tarsus 1 apparently with about 15 pseudosegments, but only about 10 quite distinct distally.

Variation. Tibia 1 in other male: 2.37. Distance between tips of distal cheliceral apophyses in other male: 0.23.

Females (paratypes). In general similar to male. Tibia 1 (n = 7): 1.8–2.12 (mean: 1.94). Epigynum simple and flat externally, with internal structures visible through cuticle (Figs 6, 33), pockets 0.15 apart. Dorsal view as in fig. 34.
