Type material.
Holotype ♂ ( IZCAS - Ar 44980 ), Yinhe Cave (26 ° 27.127 ' N, 101 ° 6.482 ' E, 2012 m), Renhe Town , Yongsheng County, Lijiang, Yunnan, China, 03 / 08 / 2010, C Wang, Q Zhao & L Lin leg. GoogleMaps
Etymology.
The specific name refers to the type locality, which is a noun in apposition.
Diagnosis.
The new species resembles B. halongensis Yao, Pham & Li, 2015 ( Yao et al. 2015: 8, figs 16 A – D, 17 A – D, 18 A – D) by having similar male chelicerae and bulbal apophyses (Fig. 15 A, B View Figure 15 ), but can be distinguished by differences in males: procursus with two sclerotized distal apophyses (arrows in Figs 14 C View Figure 14 , 19 A View Figure 19 vs one prolatero-ventral sclerite), retrolateral flap (Figs 14 D View Figure 14 , 19 B View Figure 19 vs absent) and without prolatero-distal membranous lamella (Figs 14 C View Figure 14 , 19 A View Figure 19 vs present).
Description.
Male (holotype): Total length 1.74 (1.79 with clypeus), carapace 0.58 long, 0.65 wide, opisthosoma 1.16 long, 0.80 wide. Leg I: 11.43 (3.10, 0.26, 3.03, 3.76, 1.28), leg II: 7.94 (2.25, 0.24, 1.98, 2.55, 0.92), leg III: 5.65 (1.60, 0.21, 1.38, 1.82, 0.64), leg IV: 7.29 (2.09, 0.23, 1.80, 2.48, 0.69); tibia I L / d: 47. Eye inter-distances and diameters: PME – PME 0.12, PME 0.07, PME – ALE 0.02, AME absent. Sternum width / length: 0.51 / 0.46. Habitus as in Fig. 15 C – E View Figure 15 . Carapace yellowish, with brownish radiating marks; sternum yellowish. Legs whitish, without darker rings. Opisthosoma yellowish, without spots. Thoracic furrow absent. Clypeus unmodified. Chelicerae (Fig. 15 B View Figure 15 ) with a pair of proximo-lateral apophyses and a pair of distal apophyses (distance between tips: 0.19). 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 ) and retrolatero-ventral apophysis (arrow 2 in Fig. 14 B View Figure 14 ); procursus simple proximally but complex distally, with two sclerotized distal apophyses (arrows in Figs 14 C View Figure 14 , 19 A View Figure 19 ) and nearly D-shaped retrolateral flap (Figs 14 D View Figure 14 , 19 B View Figure 19 ); bulb (Fig. 15 A View Figure 15 ) with hooked apophysis and simple embolus. Retrolateral trichobothria on tibia I at 11 % proximally; legs with short vertical setae on metatarsi; tarsus I with 20 distinct pseudosegments.
Female: Unknown.
Habitat.
The species was found in the dark zone inside the cave.
Distribution.
