Type material.

Holotype: China • ♂; Guangxi, Baise, Tianlin County, Langping Town , Dabao Village , Sanchuantun , Papa Cave ; 24 ° 34.226 ' N, 106 ° 13.675 ' E; alt. 773 m; 14 Aug. 2011; C Wang leg.; IZCAS - Ar 44988 GoogleMaps . Paratypes: China • 4 ♀; same data as for holotype; IZCAS - Ar 44989 –92 GoogleMaps .

Etymology.

The specific name refers to the type locality; noun in apposition.

Diagnosis.

The new species resembles B. phungae Yao, Pham & Li, 2015 ( Yao et al. 2015: 9, figs 19 A – D, 20 A – G, 21 A – E) by having similar male chelicerae and epigyne (Fig. 3 A, D View Figure 3 ), but can be distinguished by procursus with retrolatero-subdistal membranous lamella (arrow in Figs 2 D View Figure 2 , 8 B View Figure 8 vs. absent in B. phungae ), by bulbal apophysis hooked (ba in Fig. 3 C View Figure 3 vs. distally blunt in B. phungae ), by cheliceral proximo-lateral apophyses and distal apophyses closer to each other (Fig. 3 D View Figure 3 vs. widely separated in B. phungae ), by vulva without sac-like structure (Figs 3 B View Figure 3 , 9 B View Figure 9 vs. present in B. phungae ), and by pore plates nearly triangular (pp in Figs 3 B View Figure 3 , 9 B View Figure 9 vs. nearly round in B. phungae ); also distinguished from B. zhangi Tong & Li, 2007 ( Tong and Li 2007: 505, figs 1–6) by procursus with sclerotized prolatero-subdistal apophysis (arrow 1 in Figs 2 C View Figure 2 , 8 A View Figure 8 vs. spine in B. zhangi ), prolatero-subdistal membranous lamella (arrow 2 in Figs 2 C View Figure 2 , 8 A View Figure 8 vs. absent in B. zhangi ), and retrolatero-subdistal membranous lamella (arrow in Figs 2 D View Figure 2 , 8 B View Figure 8 vs. retrolatero-ventral in B. zhangi ), by procursus without retrolateral membranous flap (Figs 2 D View Figure 2 , 8 B View Figure 8 vs. present in B. zhangi ), by vulval anterior arch straight (aa in Figs 3 B View Figure 3 , 9 B View Figure 9 vs. ridge-shaped in B. zhangi ), and by pore plates nearly triangular (pp in Figs 3 B View Figure 3 , 9 B View Figure 9 vs. long and curved in B. zhangi ).

Description.

Male (holotype): Total length 1.11 (1.20 with clypeus), prosoma 0.40 long, 0.53 wide, opisthosoma 0.71 long, 0.54 wide. Leg I missing, leg II: 4.88 (1.30, 0.20, 1.18, 1.62, 0.58), leg III: 3.92 (1.00, 0.19, 0.96, 1.27, 0.50), leg IV: 4.76 (1.27, 0.20, 1.17, 1.55, 0.57). Eye interdistances and diameters: PME – PME 0.10, PME 0.06, PME – ALE 0.02, AME absent. Sternum width / length: 0.43 / 0.33. Habitus as in Fig. 3 E, F View Figure 3 . Dorsal shield of prosoma yellowish, with indistinct median and posterior marks; sternum yellowish, with indistinct marginal marks. Legs whitish, without darker rings. Opisthosoma yellowish, without spots. Thoracic furrow absent. Clypeus unmodified. Chelicerae with pair of proximo-lateral apophyses (pa in Fig. 3 D View Figure 3 ) and pair of distal apophyses (da in Fig. 3 D View Figure 3 ; distance between tips: 0.11). Palp as in Fig. 2 A, B View Figure 2 ; trochanter with ventral apophysis (arrow in Fig. 2 B View Figure 2 ); procursus simple proximally but complex distally, with sclerotized prolatero-subdistal apophysis (arrow 1 in Figs 2 C View Figure 2 , 8 A View Figure 8 ), prolatero-subdistal membranous lamella (arrow 2 in Figs 2 C View Figure 2 , 8 A View Figure 8 ), and retrolatero-subdistal membranous lamella (arrow in Figs 2 D View Figure 2 , 8 B View Figure 8 ); bulb with hooked apophysis (ba in Fig. 3 C View Figure 3 ) and simple embolus (e in Fig. 3 C View Figure 3 ).

Female (paratype, IZCAS - Ar 44989 ): Similar to male, habitus as in Fig. 3 G, H View Figure 3 . Total length 1.57 (1.66 with clypeus), prosoma 0.43 long, 0.56 wide, opisthosoma 1.14 long, 0.90 wide. Leg I: 6.87 (1.86, 0.24, 1.78, 2.16, 0.83); tibia I L / d: 36. Eye interdistances and diameters: PME – PME 0.06, PME 0.05, PME – ALE 0.02, AME absent. Sternum width / length: 0.40 / 0.33. Epigyne simple and flat, with pair of median pockets 0.08 apart (ep in Figs 3 A View Figure 3 , 9 A View Figure 9 ). Vulva with straight anterior arch (aa in Figs 3 B View Figure 3 , 9 B View Figure 9 ) and pair of nearly triangular pore plates (pp in Figs 3 B View Figure 3 , 9 B View Figure 9 ). Retrolateral trichobothria on tibia I at 5 % proximally; legs with short vertical setae on metatarsi; tarsus I with 16 distinct pseudosegments.

Variation.

Tibia I in other three female paratypes ( IZCAS - Ar 44990 –92): 1.80, 1.93, 1.98.

Habitat.

The species was found in the dark zone inside the cave.

Distribution.
