Type material.
Holotype: China • ♂; Guizhou, Bijie, Qixingguan District, Changchun Town, Changchun Village, Changchun Cave; 27 ° 13.904 ' N, 105 ° 10.397 ' E; alt. 1580 m; 29 Apr. 2007; J. Liu & Y. Lin leg.; IZCAS - Ar 45206. Paratypes: China • 7 ♀; same data as for holotype; IZCAS - Ar 45207 –13.
Diagnosis.
The new species resembles B. tongi Zhang, Li & Yao, 2024 (Zhang et al. 2024 b: 273, figs 12 A – D, 13 A – H, 18 K, L, 21 C, D) by having similar distal part of procursus (distal membranous process nearly half-round; arrow 1 in Figs 10 C, 22 I), bulbal apophysis (hooked; Fig. 11 C), and epigyne (epigynal pockets on postero-lateral part of epigynal plate, epigynal plate posteriorly curved; Figs 11 A, 24 I), but can be distinguished by procursus without distal membranous lamella (Figs 10 C, 22 I vs present), by male cheliceral distal apophyses pointing downwards (da in Fig. 11 D vs outwards), by vulva without teeth (Figs 11 B, 24 J vs present), and by vulval pore plates medially narrow and posteriorly strongly widened (pp in Figs 11 B, 24 J vs nearly triangular).
Description.
Male (holotype): Total length 1.78 (1.89 with clypeus), prosoma 0.68 long, 0.75 wide, opisthosoma 1.10 long, 0.77 wide. Leg I: 14.43 (3.80, 0.31, 3.72, 5.00, 1.60), leg II: – (3.00, 0.31, 2.66, 3.75, –), leg III missing, leg IV: 7.17 (2.13, 0.27, 1.66, 2.41, 0.70); tibia I L / d: 50. Eye interdistances and diameters: PME – PME 0.14, PME 0.08, PME – ALE 0.02. Sternum width / length: 0.55 / 0.48. Habitus as in Fig. 11 E, F. Dorsal shield of prosoma yellowish, with brown radiating marks; ocular area with brown median stripe; clypeus brown; sternum yellowish. Legs whitish, without darker rings. Opisthosoma yellowish, with black spots. Thoracic furrow absent. Clypeus unmodified. Chelicerae with pair of proximo-lateral apophyses (pa in Fig. 11 D) and pair of curved distal apophyses (distance between tips: 0.29; da in Fig. 11 D). Palp as in Fig. 10 A, B; trochanter with ventral apophysis (as long as wide, arrow 1 in Fig. 10 B); femur with retrolatero-proximal protrusion (arrow 2 in Fig. 10 B); procursus simple, with distal membranous process (arrow 1 in Figs 10 C, 22 I) and subdistal spine (arrow 2 in Figs 10 C, 22 I); bulb with hooked apophysis (ba in Fig. 11 C) and simple embolus (e in Fig. 11 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 45207): Similar to male, habitus as in Fig. 11 G, H. Total length 2.04 (2.15 with clypeus), prosoma 0.78 long, 0.81 wide, opisthosoma 1.26 long, 1.00 wide; tibia I: 3.08; tibia I L / d: 39. Eye interdistances and diameters: PME – PME 0.12, PME 0.08, PME – ALE 0.02. Sternum width / length: 0.55 / 0.46. Epigyne simple and flat, posteriorly curved, with pair of postero-lateral pockets 0.28 apart (ep in Figs 11 A, 24 I). Vulva with curved anterior arch (aa in Figs 11 B, 24 J), pair of medially narrow and posteriorly strongly widened pore plates (pp in Figs 11 B, 24 J), and pair of sclerotized protrusions (arrow in Figs 11 B, 24 J).
Variation.
Tibia I in the other six female paratypes (IZCAS - Ar 45208 –13): 2.89–3.09.
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.
