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 GoogleMaps . Paratypes: China • 7 ♀; same data as for holotype; IZCAS - Ar 45207 –13 GoogleMaps .

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 View Figure 10 , 22 I View Figure 22 ), bulbal apophysis (hooked; Fig. 11 C View Figure 11 ), and epigyne (epigynal pockets on postero-lateral part of epigynal plate, epigynal plate posteriorly curved; Figs 11 A View Figure 11 , 24 I View Figure 24 ), but can be distinguished by procursus without distal membranous lamella (Figs 10 C View Figure 10 , 22 I View Figure 22 vs present), by male cheliceral distal apophyses pointing downwards (da in Fig. 11 D View Figure 11 vs outwards), by vulva without teeth (Figs 11 B View Figure 11 , 24 J View Figure 24 vs present), and by vulval pore plates medially narrow and posteriorly strongly widened (pp in Figs 11 B View Figure 11 , 24 J View Figure 24 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 View Figure 11 . 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 View Figure 11 ) and pair of curved distal apophyses (distance between tips: 0.29; da in Fig. 11 D View Figure 11 ). Palp as in Fig. 10 A, B View Figure 10 ; trochanter with ventral apophysis (as long as wide, arrow 1 in Fig. 10 B View Figure 10 ); femur with retrolatero-proximal protrusion (arrow 2 in Fig. 10 B View Figure 10 ); procursus simple, with distal membranous process (arrow 1 in Figs 10 C View Figure 10 , 22 I View Figure 22 ) and subdistal spine (arrow 2 in Figs 10 C View Figure 10 , 22 I View Figure 22 ); bulb with hooked apophysis (ba in Fig. 11 C View Figure 11 ) and simple embolus (e in Fig. 11 C View Figure 11 ). 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 View Figure 11 . 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 View Figure 11 , 24 I View Figure 24 ). Vulva with curved anterior arch (aa in Figs 11 B View Figure 11 , 24 J View Figure 24 ), pair of medially narrow and posteriorly strongly widened pore plates (pp in Figs 11 B View Figure 11 , 24 J View Figure 24 ), and pair of sclerotized protrusions (arrow in Figs 11 B View Figure 11 , 24 J View Figure 24 ).
