Type material.
Holotype: China • ♂; Guizhou, Liupanshui, Pan County, Biyun Cave; 25 ° 46.527 ' N, 104 ° 38.278 ' E; alt. 1468 m; 13 Apr. 2007; J. Liu & Y. Lin leg.; IZCAS - Ar 45181. Paratypes: China • 5 ♂; same data as for holotype; IZCAS - Ar 45182 –86 • 7 ♀; same data as for holotype; IZCAS - Ar 45187 –93.
Diagnosis.
The new species resembles B. jiuxiang Zhang, Li & Yao, 2024 (Zhang et al. 2024 b: 261, figs 4 A – D, 5 A – H, 18 C, D, 20 C, D) by having similar male chelicerae (distal apophyses directed towards frontally, but tips pointing inwards; Fig. 5 D) and epigyne (epigynal pockets on median part of epigynal plate, epigynal plate posteriorly straight; Figs 5 A, 24 C), but can be distinguished by procursus with prolatero-subdistal and subdistal membranous processes (arrows 1, 3 in Figs 4 C, 22 C vs absent) and nearly rectangle dorso-subdistal membranous process (arrow 4 in Figs 4 C, 22 C vs angular), by bulbal apophysis with angular subdistal apophysis (arrow in Fig. 5 C vs absent), and by vulval pore plates anteriorly narrow and posteriorly wide (pp in Figs 5 B, 24 D vs nearly quadrilateral).
Description.
Male (holotype): Total length 1.71 (1.79 with clypeus), prosoma 0.63 long, 0.67 wide, opisthosoma 1.08 long, 0.81 wide. Leg I: – (4.04, 0.29, 4.50, 5.96, –), leg II: 11.08 (2.80, 0.30, 2.97, 3.92, 1.09), leg III: 7.98 (2.22, 0.25, 1.98, 2.72, 0.81), leg IV: 10.20 (3.00, 0.26, 2.63, 3.45, 0.86); tibia I L / d: 63. Eye interdistances and diameters: PME – PME 0.09, PME 0.08, PME – ALE 0.02. Sternum width / length: 0.51 / 0.44. Habitus as in Fig. 5 E, F. Dorsal shield of prosoma yellowish, with brownish radiating marks; clypeus brownish; 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. 5 D) and pair of curved distal apophyses (distance between tips: 0.17; da in Fig. 5 D). Palp as in Fig. 4 A, B; trochanter with ventral apophysis (as long as wide, arrow 1 in Fig. 4 B); femur with retrolatero-proximal protrusion (arrow 2 in Fig. 4 B); procursus simple proximally but complex distally, with prolatero-subdistal membranous process (arrow 1 in Figs 4 C, 22 C), sclerotized distal apophysis (arrow 2 in Figs 4 C, 22 C), subdistal membranous process (arrow 3 in Figs 4 C, 22 C), dorso-subdistal membranous process (arrow 4 in Figs 4 C, 22 C), and retrolateral membranous flap (f in Figs 4 D, 22 D); bulb with hooked apophysis bearing angular subdistal apophysis (arrow in Fig. 5 C) and simple embolus (e in Fig. 5 C). Retrolateral trichobothria on tibia I at 4 % proximally; legs with short vertical setae on metatarsi.
Female (paratype, IZCAS - Ar 45187): Similar to male, habitus as in Fig. 5 G, H. Total length 2.53 (2.65 with clypeus), prosoma 0.67 long, 0.75 wide, opisthosoma 1.86 long, 1.80 wide; tibia I: 4.05; tibia I L / d: 51. Eye interdistances and diameters: PME – PME 0.11, PME 0.07, PME – ALE 0.02. Sternum width / length: 0.52 / 0.46. Epigyne simple and flat, posteriorly straight, with pair of median pockets 0.20 apart (ep in Figs 5 A, 24 C). Vulva with ridge-shaped anterior arch bearing pair of angular lateral sclerites (arrow in Figs 5 B, 24 D), and pair of anteriorly narrow and posteriorly wide pore plates (3 × longer than wide, pp in Figs 5 B, 24 D).
Variation.
Tibia I in five male paratypes (IZCAS - Ar 45182 –86): 4.50, 4.55, 4.62, 4.65, 4.70. Tibia I in the other six female paratypes (IZCAS - Ar 45188 –93): 3.56–3.85.
Habitat.
The species was found in the dark zone inside the cave.
Distribution.
China (Guizhou, type locality; Fig. 1).
Etymology.
The specific name refers to the type locality; noun in apposition.
