Type material.

Holotype: China • ♂; Guizhou, Zunyi, Tongzi County, Leishanguan Town, Yangliuping Village; 28 ° 08.692 ' N, 106 ° 47.378 ' E; alt. 1008 m; 11 May 2007; J. Liu & Y. Lin leg.; IZCAS - Ar 45229 . Paratypes: China • 4 ♂; same data as for holotype; IZCAS - Ar 45230 –33 • 13 ♀; same data as for holotype; IZCAS - Ar 45234 –46 .

Diagnosis.

The new species resembles B. zhangi Tong & Li, 2007 (Tong and Li 2007: 505, figs 1–6) by having similar bulbal apophysis (hooked; Fig. 21 C) and vulva (anterior arch ridge-shaped, pore plates long elliptic and 6 × longer than wide; Figs 21 B, 25 J), but can be distinguished by procursus with dorso-subdistal membranous process (arrow 3 in Figs 20 C, 23 G vs sclerotized apophysis) and without ventro-subdistal membranous lamella (Figs 20 C, 23 G vs present), by tips of male cheliceral distal apophyses close to each other (da in Fig. 21 D vs widely separated), and by epigyne with median pockets (ep in Figs 21 A, 25 I vs postero-median).

Description.

Male (holotype): Total length 1.62 (1.72 with clypeus), prosoma 0.60 long, 0.66 wide, opisthosoma 1.02 long, 0.78 wide. Leg I: 13.53 (3.60, 0.29, 3.50, 4.60, 1.54), leg II: 8.40 (2.25, 0.30, 2.08, 2.81, 0.96), leg III: 5.69 (1.64, 0.25, 1.34, 1.86, 0.60), leg IV: 7.72 (2.12, 0.24, 2.00, 2.56, 0.80); tibia I L / d: 43. Eye interdistances and diameters: PME – PME 0.09, PME 0.08, PME – ALE 0.02. Sternum width / length: 0.53 / 0.47. Habitus as in Fig. 21 E, F. Dorsal shield of prosoma yellowish, without marks; clypeus and sternum yellowish. Legs whitish, without darker rings. Opisthosoma yellowish, without spots. Thoracic furrow absent. Clypeus unmodified. Chelicerae with pair of proximo-lateral apophyses (pa in Fig. 21 D) and pair of curved distal apophyses (distance between tips: 0.04; da in Fig. 21 D). Palp as in Fig. 20 A, B; trochanter with ventral apophysis (as long as wide, arrow 1 in Fig. 20 B); femur with retrolatero-proximal protrusion (arrow 2 in Fig. 20 B); procursus simple proximally but complex distally, with prolatero-distal membranous lamella (arrow 1 in Figs 20 C, 23 G) bearing proximally sclerotized part, dorso-distal spine (arrow 2 in Figs 20 C, 23 G), dorso-subdistal membranous process (arrow 3 in Figs 20 C, 23 G), and retrolateral membranous flap (f in Figs 20 D, 23 H); bulb with hooked apophysis (ba in Fig. 21 C) and simple embolus (e in Fig. 21 C). Retrolateral trichobothria on tibia I at 10 % proximally; legs with short vertical setae on metatarsi; tarsus I with 15 distinct pseudosegments.

Female (paratype, IZCAS - Ar 45234): Similar to male, habitus as in Fig. 21 G, H. Total length 1.57 (1.66 with clypeus), prosoma 0.60 long, 0.68 wide, opisthosoma 0.97 long, 0.78 wide; tibia I: 2.33; tibia I L / d: 35. Eye interdistances and diameters: PME – PME 0.08, PME 0.06, PME – ALE 0.02. Sternum width / length: 0.50 / 0.46. Epigyne simple and flat, posteriorly straight, with pair of median pockets 0.06 apart (ep in Figs 21 A, 25 I). Vulva with ridge-shaped anterior arch (aa in Figs 21 B, 25 J) and pair of long elliptic pore plates (6 × longer than wide, pp in Figs 21 B, 25 J).

Variation.

Tibia I in four male paratypes (IZCAS - Ar 45230 –45233): 3.12, 3.20, 3.28, 3.70. Tibia I in the other 12 female paratypes (IZCAS - Ar 45235 –46): 2.31–2.50.

Habitat.

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