Type material.
Holotype ♂ ( IZCAS - Ar 44949 ) and paratypes 2 ♂ ( IZCAS - Ar 44950 –51 ) 3 ♀ ( IZCAS - Ar 44952 –54 ), Yanzi Cave (23 ° 38.220 ' N, 103 ° 3.200 ' E, 1080 m), Mawangzhuang , Miandian Town, Jianshui County, Honghe, Yunnan, China, 29 / 03 / 2007, J Liu & Y Lin leg. GoogleMaps
Etymology.
The specific name refers to the type locality, which is a noun in apposition.
Diagnosis.
The new species resembles B. cheni Yao, Pham & Li, 2015 ( Yao et al. 2015: 5, figs 4 A – D, 5 A – G, 6 A – E) by having similar male chelicerae, bulbal apophyses, and epigyne (Figs 3 A, C, D View Figure 3 , 20 A View Figure 20 ), but can be distinguished by differences in males: procursus with nearly trapezoidal dorso-distal membranous process (arrow 3 in Figs 2 C View Figure 2 , 18 A View Figure 18 vs half-round) and long (as long as dorso-distal membranous process), distally widened ventro-subdistal membranous process (arrow 4 in Figs 2 C View Figure 2 , 18 A View Figure 18 vs short and distally pointed); differences in females: pore plates anteriorly pointed and posteriorly wide and blunt (Figs 3 B View Figure 3 , 20 B View Figure 20 vs narrow).
Description.
Male (holotype): Total length 1.66 (1.74 with clypeus), carapace 0.63 long, 0.67 wide, opisthosoma 1.03 long, 0.84 wide. Leg I: 19.02 (5.05, 0.26, 5.00, 7.05, 1.66), leg II: 14.38 (3.96, 0.25, 3.80, 5.15, 1.22), leg III missing, leg IV: 10.65 (3.16, 0.23, 2.53, 3.96, 0.77); tibia I L / d: 89. Eye inter-distances and diameters: PME – PME 0.13, PME 0.07, PME – ALE 0.02, AME absent. Sternum width / length: 0.50 / 0.46. Habitus as in Fig. 3 E, F View Figure 3 . Carapace and sternum yellowish, without marks. Legs whitish, without darker rings. Opisthosoma yellowish, without spots. Thoracic furrow absent. Clypeus unmodified. Chelicerae (Fig. 3 D View Figure 3 ) with a pair of proximo-lateral apophyses and a pair of distal apophyses (distance between tips: 0.19). Palp as in Fig. 2 A, B View Figure 2 ; trochanter with ventral apophysis (arrow 2 in Fig. 2 B View Figure 2 ) and prolateral apophysis (arrow 1 in Fig. 2 B View Figure 2 ); procursus simple proximally but complex distally, with sclerotized prolatero-distal apophysis (arrow 1 in Figs 2 C View Figure 2 , 18 A View Figure 18 ), sclerotized distal apophysis (arrow 2 in Figs 2 C View Figure 2 , 18 A View Figure 18 ), dorso-distal membranous process (arrow 3 in Figs 2 C View Figure 2 , 18 A View Figure 18 ), ventro-subdistal membranous process (arrow 4 in Figs 2 C View Figure 2 , 18 A View Figure 18 ), and retrolateral flap (Figs 2 D View Figure 2 , 18 B View Figure 18 ); bulb (Fig. 3 C View Figure 3 ) with hooked apophysis and simple embolus. Retrolateral trichobothria on tibia I at 9 % proximally; legs with short vertical setae on metatarsi; tarsus I with 20 distinct pseudosegments.
Female (paratype, IZCAS - Ar 44952 ): Similar to male, habitus as in Fig. 3 G, H View Figure 3 . Total length 1.50 (1.62 with clypeus), carapace 0.49 long, 0.55 wide, opisthosoma 1.01 long, 0.80 wide; tibia I: 3.60; tibia I L / d: 61. Eye inter-distances and diameters: PME – PME 0.14, PME 0.06, PME – ALE 0.02, AME absent. Sternum width / length: 0.47 / 0.44. Epigyne (Figs 3 A View Figure 3 , 20 A View Figure 20 ) simple and flat, with a pair of postero-lateral pockets 0.32 apart (arrow ep in Figs 3 B View Figure 3 , 20 B View Figure 20 , invisible in Figs 3 A View Figure 3 , 20 A View Figure 20 ). Vulva (Figs 3 B View Figure 3 , 20 B View Figure 20 ) with ridge-shaped anterior arch and a pair of anteriorly pointed and posteriorly wide and blunt pore plates.
Variation.
Tibia I in one male paratype ( IZCAS - Ar 44950 ) (leg I missing in IZCAS - Ar 44951 ): 5.64. Tibia I in the other two female paratypes ( IZCAS - Ar 44953 –54 ): 4.10, 4.25.
Habitat.
The species was found in the dark zone inside the cave.
Distribution.
China (Yunnan, type locality; Fig. 1 View Figure 1 ).
