Description
Male (holotype): Total length 2.06 (2.22 with clypeus), prosoma 0.76 long, 0.84 wide, opisthosoma 1.30 long, 0.88 wide. Leg I: 22.48 (6.11, 0.38, 5.58, 8.41, 2.00), leg II: 14.50 (4.06, 0.36, 3.68, 5.00, 1.40), leg III: 9.88 (2.75, 0.34, 2.36, 3.40, 1.03), leg IV: 12.73 (3.68, 0.35, 3.24, 4.40, 1.06). tibia I L / d: 63. Eye intervals and diameters: PME-PME 0.16, PME 0.08, PME-ALE 0.02, AME absent. Sternum as wide as long (0.58). Habitus as in Fig. 2 View Figure 2 E and F. Carapace of prosoma yellowish, with brown radiating marks; ocular area and clypeus brown; sternum brownish. Legs whitish, without darker rings. Opisthosoma yellowish, with dark brown spots. Thoracic furrow absent. Clypeus unmodified. Chelicerae (Fig. 2 View Figure 2 D) with pair of proximo-lateral apophyses and pair of curved distal apophyses (distance between tips: 0.36). Palp as in Fig. 1 View Figure 1 A and B; trochanter with ventral apophysis (as long as wide, arrow 1 in Fig. 1 View Figure 1 B); femur with small retrolatero-proximal protrusion (arrow 2 in Fig. 1 View Figure 1 B); procursus simple proximally, but complex distally, with prolatero-subdistal sclerite (arrow 1 in Fig. 1 View Figure 1 C and Fig. 3 View Figure 3 A), distal membranous lamella (arrow 2 in Fig. 1 View Figure 1 C and Fig. 3 View Figure 3 A) bearing proximal sclerotised part, curved distal spine (arrow 3 in Fig. 1 View Figure 1 C and Fig. 3 View Figure 3 A), sclerotised dorsal apophysis (arrow 4 in Fig. 1 View Figure 1 C and Fig. 3 View Figure 3 A) and nearly trapezoidal retrolateral membranous lamella (f in Fig. 1 View Figure 1 D and Fig. 3 View Figure 3 B); bulb (Fig. 2 View Figure 2 C) with hooked apophysis and simple embolus. Retrolateral trichobothrium on tibia I at 8 % proximally; legs with short vertical setae on metatarsi; tarsus I with 22 distinct pseudosegments.
Female (paratype, SYNU-Ar 00408): Similar to male, habitus as in Fig. 2 View Figure 2 G and H. Total length 2.16 (2.35 with clypeus), prosoma 0.72 long, 0.87 wide, opisthosoma 1.44 long, 1.25 wide. tibia I: 4.04; tibia I L / d: 54. Eye intervals and diameters: PME-PME 0.12, PME 0.09, PME-ALE 0.02, AME absent. Sternum as wide as long (0.60). Epigyne (Fig. 2 View Figure 2 A and Fig. 3 View Figure 3 C) simple and flat, brown, with pair of lateral pockets 0.41 apart. Vulva (Fig. 2 View Figure 2 B and Fig. 3 View Figure 3 D) with ridge-shaped anterior arch and pair of long (8 times longer than wide), curved pore plates.
Diagnosis
The new species resembles B. yuhaoi Yang & Yao, 2023 ( Yang et al. 2023: figs. 2 A – B, 3 A – D and 4 A – H) by having similar bulbal apophyses (Fig. 2 View Figure 2 C), but can be distinguished by procursus without prolatero-ventral lamella (Fig. 1 View Figure 1 C and Fig. 3 View Figure 3 A; vs. present), by procursus with nearly trapezoidal retrolateral membranous flap (Fig. 1 View Figure 1 D and Fig. 3 View Figure 3 B; vs. angular), by distal apophyses of male chelicerae pointing forwards (Fig. 2 View Figure 2 D; vs. downwards), by epigyne with pair of lateral pockets (Fig. 2 View Figure 2 A, B, Fig. 3 View Figure 3 C and D; vs. posterior) and by pore plates long and curved (8 times longer than wide, Fig. 2 View Figure 2 B and Fig. 3 View Figure 3 D; vs. nearly triangular).
Etymology
The specific name is a patronym in honour of the collector Cheng Wang (Tongren University); noun (name) in the genitive case.
Distribution
China (Guizhou, Tongren, Jiangkou County, Nujiang Town, Hekou Village, Shenjia Cave).
