Male , China , Guangxi , Laibin City , Xiangzhou County , Xiangzhou Town , cave without name, 23°57.278´N , 109°39.696´E , elev. 114 m , 10 October 2010 , X. Wang & L. Lin leg., deposited in IZCAS . Paratypes . 24 females , same data as holotype, deposited in IZCAS . Etymology. The specific name is a patronym in honor of Prof. Yanfeng Tong from Shenyang Normal University in Shenyang; noun in apposition. Prof. Tong is a leading taxonomist in Oonopidae in China . Diagnosis. This new species is similar to B. punctosparsa (Song, Zhu & Chen, 1999: 363, figs 213K–N), but can be distinguished by the oar-shaped dictynid TA dorsal apophysis, ending with row of denticles (acuminate and hooked in B. punctosparsa ), medial apophysis short finger-shaped (obtuse triangle-shaped in B. punctosparsa ).
