Diagnosis and description of male. See Yao et al. (2015).

Female (SYNU-Ar00330): Similar to male, habitus as in Figs 8C–D. Total length 1.57 (1.68 with clypeus), prosoma 0.56 long, 0.50 wide, opisthosoma 1.01 long, 0.73 wide; tibia I: 2.63; tibia I L/d: 47. Eye interdistances and diameters: PME-PME 0.13, PME 0.07, PME-ALE 0.01, AME absent. Sternum width/length: 0.59/0.41. Epigyne (Figs 8A, 10E) simple and flat, with four spine-shaped apophyses (lateral two forked) and pair of postero-lateral pockets 0.25 apart (ep in Figs 8B, 10F). Vulva (Figs 8B, 10F) with relatively straight anterior arch and pair of long, laterally strongly widened pore plates.

Variation: Tibia I in the other four female specimens (SYNU-Ar00331–00334) (leg I missing in the other female specimen SYNU-Ar00335): 2.13, 2.15, 2.31, 2.35.

Natural history. The species was collected in rubber plantation by canopy fogging.

Distribution. China (Yunnan, Fig. 1), Vietnam (Vinh Phuc, type locality; see Yao et al. 2015: 82, fig. 61).

Remarks. We have examined the type material and other material of B. zhengi from IZCAS. The specimens from the collection of SYNU are assigned to B. zhengi, because their male morphological characters are consistent with Yao et al. ’s (2015) diagnosis and description, e.g., procursus with long, flat, dark prolatero-subdistal apophysis and leaf-shaped retrolatero-subdistal membranous flap, male chelicerae without proximo-lateral apophysis.
