Type material.
Holotype: China • ♂; Guizhou, Qiandongnan, Liping County, Yongcong Town, Guantuan Village, Guantuan Cave ; 25 ° 59.028 ' N, 109 ° 06.979 ' E; alt. 544 m; 23 May 2007; J. Liu & Y. Lin leg.; IZCAS - Ar 45218 GoogleMaps . Paratypes: China • 2 ♂; same data as for holotype; IZCAS - Ar 45219 –20 GoogleMaps • 5 ♀; same data as for holotype; IZCAS - Ar 45221 –25 GoogleMaps .
Diagnosis.
The new species resembles B. nayong sp. nov. (Figs 8 View Figure 8 , 9 View Figure 9 , 22 G, H View Figure 22 , 24 G, H View Figure 24 ) by having similar bulbal apophysis (hooked; Fig. 15 C View Figure 15 ) and vulva (anterior arch ridge-shaped, pore plates curved, long elliptic and 8 × longer than wide; Figs 15 B View Figure 15 , 25 D View Figure 25 ), but can be distinguished by procursus with blunt ventro-subdistal membranous process (arrow 1 in Figs 14 C View Figure 14 , 23 A View Figure 23 vs pointed), by male cheliceral distal apophyses pointing outwards (da in Fig. 15 D View Figure 15 vs inwards), and by epigyne with lateral pockets (ep in Figs 15 A View Figure 15 , 25 C View Figure 25 vs postero-median).
Description.
Male (holotype): Total length 1.73 (1.82 with clypeus), prosoma 0.83 long, 0.67 wide, opisthosoma 0.90 long, 0.66 wide. Leg I: 14.76 (3.60, 0.34, 4.05, 5.58, 1.56), leg II: 12.45 (3.36, 0.32, 3.08, 4.60, 1.09), leg III: 8.21 (2.38, 0.26, 1.98, 2.84, 0.75), leg IV: 10.64 (3.20, 0.26, 2.66, 3.72, 0.80); tibia I L / d: 46. Eye interdistances and diameters: PME – PME 0.06, PME 0.09, PME – ALE 0.02. Sternum width / length: 0.54 / 0.49. Habitus as in Fig. 15 E, F View Figure 15 . Dorsal shield of prosoma yellowish, with brownish radiating 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. 15 D View Figure 15 ) and pair of curved distal apophyses (distance between tips: 0.32; da in Fig. 15 D View Figure 15 ). Palp as in Fig. 14 A, B View Figure 14 ; trochanter with ventral apophysis (as long as wide, arrow 1 in Fig. 14 B View Figure 14 ); femur with retrolatero-proximal protrusion (arrow 2 in Fig. 14 B View Figure 14 ); procursus simple proximally but complex distally, with ventro-subdistal membranous lamella (arrow 1 in Figs 14 C View Figure 14 , 23 A View Figure 23 ) bearing proximally sclerotized part, prolatero-distal membranous lamella (arrow 2 in Figs 14 C View Figure 14 , 23 A View Figure 23 ) bearing proximally sclerotized part, sclerotized dorso-subdistal apophysis (arrow 3 in Figs 14 C View Figure 14 , 23 A View Figure 23 ), and retrolateral membranous flap (f in Figs 14 D View Figure 14 , 23 B View Figure 23 ); bulb with hooked apophysis (ba in Fig. 15 C View Figure 15 ) and simple embolus (e in Fig. 15 C View Figure 15 ). Retrolateral trichobothria on tibia I at 10 % proximally; legs with short vertical setae on metatarsi; tarsus I with 20 distinct pseudosegments.
Female (paratype, IZCAS - Ar 45221 ): Similar to male, habitus as in Fig. 15 G, H View Figure 15 . Total length 2.17 (2.29 with clypeus), prosoma 0.87 long, 0.76 wide, opisthosoma 1.30 long, 1.08 wide; tibia I: 3.65; tibia I L / d: 47. Eye interdistances and diameters: PME – PME 0.09, PME 0.08, PME – ALE 0.02. Sternum width / length: 0.59 / 0.45. Epigyne simple and flat, posteriorly curved, with pair of lateral pockets 0.35 apart (ep in Figs 15 A View Figure 15 , 25 C View Figure 25 ). Vulva with ridge-shaped anterior arch (aa in Figs 15 B View Figure 15 , 25 D View Figure 25 ) and pair of curved, long elliptic pore plates (9 × longer than wide, pp in Figs 15 B View Figure 15 , 25 D View Figure 25 ).
Variation.
Tibia I in one male paratype ( IZCAS - Ar 45219 ): 5.32 (leg I missing in IZCAS - Ar 45220 ). Tibia I in the other four female paratypes ( IZCAS - Ar 45222 –25): 3.76, 3.85, 3.96, 4.16.
Habitat.
The species was found in the dark zone inside the cave.
Distribution.
China (Guizhou, type locality; Fig. 1 View Figure 1 ).
Etymology.
The specific name refers to the type locality; noun in apposition.
