Type material.
Holotype ♂ ( IZCAS - Ar 44975 ) and paratype s 4 ♀ ( IZCAS - Ar 44976–79 ), Heilongtan Park (26 ° 53.259 ' N, 100 ° 14.034 ' E, 2155 m), Lijiang, Yunnan, China, 15 / 07 / 2021, Y Tong & D Bian leg. GoogleMaps
Etymology.
The specific name is a patronym in honour of the collector Yanfeng Tong, which is a noun (name) in the genitive case.
Diagnosis.
The new species resembles B. yangi Zhang & Peng, 2011 ( Zhang and Peng 2011: 65, fig. 11 A – H) by having similar male chelicerae, bulbal apophyses, and epigyne (Figs 13 A, C, D View Figure 13 , 21 C View Figure 21 ), but can be distinguished by differences in males: procursus with distal membranous process (arrow 2 in Figs 12 C View Figure 12 , 18 K View Figure 18 vs absent) and dorso-distal spine (arrow 3 in Figs 12 C View Figure 12 , 18 K View Figure 18 vs absent); differences in females: epigyne with posterior pockets (Figs 13 A, B View Figure 13 , 21 C, D View Figure 21 vs anterior), vulva with four distinct median teeth (arrows in Figs 13 B View Figure 13 , 21 D View Figure 21 vs absent), pore plates nearly triangular (Figs 13 B View Figure 13 , 21 D View Figure 21 vs elliptic).
Description.
Male (holotype): Total length 1.96 (2.08 with clypeus), carapace 0.71 long, 0.75 wide, opisthosoma 1.25 long, 0.80 wide. Leg I: 12.57 (3.30, 0.32, 3.22, 4.50, 1.23), leg II: 8.49 (2.35, 0.28, 2.03, 2.88, 0.95), leg III missing, leg IV: 7.38 (2.15, 0.26, 1.84, 2.43, 0.70); tibia I L / d: 45. Eye inter-distances and diameters: PME – PME 0.12, PME 0.08, PME – ALE 0.02, AME absent. Sternum width / length: 0.51 / 0.48. Habitus as in Fig. 13 E, F View Figure 13 . Carapace yellowish, with a pair of curved median bands; sternum yellowish. Legs yellowish, without darker rings. Opisthosoma yellowish, with dorsal and lateral black spots. Thoracic furrow absent. Clypeus unmodified. Chelicerae (Fig. 13 D View Figure 13 ) with a pair of proximo-lateral apophyses and a pair of long, curved distal apophyses (distance between tips: 0.49). Palp as in Fig. 12 A, B View Figure 12 ; trochanter with ventral apophysis (as long as wide; arrow in Fig. 12 A View Figure 12 ) and small retrolateral apophysis (arrow 1 in Fig. 12 B View Figure 12 ); femur with distinct ventral protrusion (arrow 2 in Fig. 12 B View Figure 12 ); procursus simple proximally but complex distally, with narrow sclerite and teeth on prolatero-subdistal part (arrow 1 in Figs 12 C View Figure 12 , 18 K View Figure 18 ), distal membranous process (arrow 2 in Figs 12 C View Figure 12 , 18 K View Figure 18 ), and dorso-distal spine (arrow 3 in Figs 12 C View Figure 12 , 18 K View Figure 18 ); bulb (Fig. 13 C View Figure 13 ) with hooked apophysis and simple embolus. Retrolateral trichobothria on tibia I at 7 % proximally; legs with short vertical setae on metatarsi; tarsus I with 16 distinct pseudosegments.
Female (paratype, IZCAS - Ar 44976 ): Similar to male, habitus as in Fig. 13 G, H View Figure 13 . Total length 2.13 (2.21 with clypeus), carapace 0.68 long, 0.70 wide, opisthosoma 1.45 long, 1.00 wide; tibia I: 2.91; tibia I L / d: 36. Eye inter-distances and diameters: PME – PME 0.11, PME 0.07, PME – ALE 0.02, AME absent. Sternum width / length: 0.55 / 0.53. Epigyne (Figs 13 A View Figure 13 , 21 C View Figure 21 ) simple and flat, anteriorly slightly sclerotized, with dark internal shade and a pair of postero-lateral pockets 0.46 apart. Vulva (Figs 13 B View Figure 13 , 21 D View Figure 21 ) with ridge-shaped anterior arch, a pair of nearly triangular pore plates bearing distinct teeth, and four distinct median teeth (arrows in Figs 13 B View Figure 13 , 21 D View Figure 21 ).
Variation.
Tibia I in the other three female paratypes ( IZCAS - Ar 44977 –79 ): 2.25, 2.47, 2.55.
Habitat.
The species was found in the leaf litter.
Distribution.
China (Yunnan, type locality; Fig. 1 View Figure 1 ).
