Type material. Holotype: Female, CHINA: Yunnan Province, Mengla County, Menglun Nature Reserve, from canopy of the primary tropical seasonal rain forest, 21°57.669ʹ N, 101°11.893ʹ E, alt. 790± 15 m, 7 July 2007, G. Zheng leg. Paratypes: 2 females, same data as for holotype ( IZCAS); 4 females, Menglun Nature Reserve, from canopy of the secondary tropical montane evergreen broad-leaved forest, 21°57.809ʹ N, 101°12.173ʹ E, alt. 633± 17 m, 4 August 2007, G. Zheng leg.

Etymology. The specific name is derived from the Latin word ‘ sinuata ’, meaning ‘wind in and out’ and refers to the curved copulatory ducts; adjective.

Diagnosis. Females of the new species similar to those of B. tibialis sp. nov. ( Figs 4 View FIGURE 4 D–E, 6D–E) in having the same appearance, anteriorly located, slit-like copulatory openings and similar structure of epigyne, but can be distinguished by the longer copulatory ducts ( Figs 2 View FIGURE 2 B, 3H) and the shape of spermathecae ( Figs 2 View FIGURE 2 B, 3H).

Description. Female. Total length 1.50–1.80. Holotype ( Figs 2 View FIGURE 2 A–F): total length 1.80. Prosoma 0.79 long, 0.64 wide; opisthosoma 1.14 long, 0.72 wide. ALE 0.077, PME 0.060, PLE 0.075; ALE–ALE 0.048, PME–PME 0.046, PME–PLE 0.028, ALE–PLE 0.010. Clypeus smaller than the radius of ALE. Chelicerae with 2 or 3 promarginal and 3 or 4 retromarginal teeth. Calamistrum consisting of 6 curved setae. Leg measurements: I 1.72 (0.56, 0.61, 0.35, 0.21), II 1.43 (0.46, 0.48, 0.29, 0.20), III 1.13 (0.38, 0.38, 0.22, 0.15), IV 1.54 (0.52, 0.55, 0.30, 0.17). Leg formula: 1423.

Epigyne ( Figs 2 View FIGURE 2 A–B, 3G–H) with a pair of copulatory openings located anteriorly. Copulatory ducts slender and strongly curved. Spermathecae curved like “7” (left part). Fertilization ducts slender and pointing anterior-laterally, widely separated from each other.

Male unknown.

Distribution. Known only from the rainforest canopy of Xishuangbanna, Yunnan Province, China.
