Type material.
Holotype: ♂ (SYNU-Ar00301), cave without a name (27°5.40'N, 106°30.00'E, 1109 m), Liutong Town, Xiuwen County, Guiyang, Guizhou, China, 5 June 2022, H Yu & Q Lu leg. Paratypes: 2♂ (SYNU-Ar00302, Ar00303) and 3♀ (SYNU-Ar00304-00306), same data as for the holotype. 1♀ (SYNU-Ar00307), Duobing Cave (27°6.00'N, 106°30.00'E, 1026 m), other data as for the holotype.
Etymology.
The specific name is a patronym in honor of the collector Hao Yu; noun (name) in genitive case.
Diagnosis.
The new species resembles B. galeiformis Zhang & Peng, 2011 ( Zhang and Peng 2011: 52, fig. 1A-F) with similar male chelicerae and bulbal apophysis (Fig. 4C, D View Figure 4 ), but it can be distinguished by prolatero-ventral lamella of procursus nearly round (arrow 2 in Fig. 3C View Figure 3 ; nearly angular in B. galeiformis ), by distal membranous lamella of procursus laterally weak sclerotized (sclerotized part nearly half-round, arrow 3 in Fig. 3C View Figure 3 ; with triangular sclerite in B. galeiformis ), by procursus with triangular retrolateral membranous flap (f in Fig. 3D View Figure 3 ; flap large and half-round in B. galeiformis ), by epigynal plate nearly round, posteriorly strongly curved (Fig. 4A View Figure 4 ; hat-shaped, posteriorly straight in B. galeiformis ), and by vulval pore plates nearly triangular (Fig. 4B View Figure 4 ; long elliptic in B. galeiformis ).
Description.
Male (holotype, SYNU-Ar00301): total length 1.93 (2.03 with clypeus), prosoma 0.74 long, 0.78 wide, opisthosoma 1.19 long, 0.96 wide. Legs I and IV missing, femur II: 3.92 (other segments missing), leg III: 10.18 (2.97, 0.33, 2.48, 3.56, 0.84). Eye interdistances and diameters: PME-PME 0.13, PME 0.10, PME-ALE 0.04, AME absent. Sternum width/length: 0.65/0.62. Habitus as in Fig. 4E, F View Figure 4 . Dorsal shield of prosoma yellowish, with large, brown radiating marks; ocular area and clypeus yellowish, with brown marks; sternum yellowish, with triangular posterior brown marks. Legs whitish, without darker rings. Opisthosoma yellowish, with dorsal and lateral brown spots. Ocular area not elevated. Thoracic furrow absent. Clypeus unmodified. Chelicerae as in Fig. 4D View Figure 4 , with a pair of proximo-lateral apophyses and a pair of curved distal apophyses (distance between tips of distal apophyses: 0.21). Palp as in Fig. 3A, B View Figure 3 ; trochanter with short retrolatero-ventral apophysis; femur with small retrolatero-proximal protrusion; procursus simple proximally but complex distally, with prolatero-subdistal sclerite (arrow 1 in Fig. 3C View Figure 3 ), sclerotized prolatero-ventral lamella (arrow 2 in Fig. 3C View Figure 3 ), distal membranous lamella (arrow 3 in Fig. 3C View Figure 3 ), curved distal spine (arrow 4 in Fig. 3C View Figure 3 ), sclerotized dorsal apophysis (arrow 5 in Fig. 3C View Figure 3 ), and angular retrolateral membranous flap (f in Fig. 3D View Figure 3 ); bulb (Fig. 4C View Figure 4 ) with hooked apophysis and simple embolus.
Female (paratype, SYNU-Ar00304): similar to male, habitus as in Fig. 4G, H View Figure 4 . Total length 2.03 (2.13 with clypeus), prosoma 0.83 long, 0.91 wide, opisthosoma 1.20 long, 1.04 wide; tibia I: 4.02; tibia I L/d: 50. Eye interdistances and diameters: PME-PME 0.12, PME 0.08, PME-ALE 0.03, AME absent. Sternum width/length: 0.58/0.51. Epigyne (Fig. 4A View Figure 4 ) simple and flat, with brown marks and a pair of posterior pockets, 0.17 apart (ep in Fig. 4A, B View Figure 4 ). Vulva (Fig. 4B View Figure 4 ) with ridge-shaped anterior arch and a pair of nearly triangular pore plates.
Variation.
In one male paratype (SYNU-Ar00302), leg I: 23.28 (6.02, 0.39, 5.71, 9.36, 1.80); tibia I L/d: 60. Retrolateral trichobothrium of tibia I at 6% proximally; legs with short vertical setae on metatarsi, without spines and curved setae; tarsus I with 22 distinct pseudosegments. Tibia I in another male paratype (SYNU-Ar00303): 5.38. Tibia I in the other two female paratypes (SYNU-Ar00305, Ar00306): 3.28, 3.75 (leg I missing in SYNU-Ar00307).
Habitat.
The species was found inside cave.
Distribution.
