Diagnosis. This species resembles B. colubrina Zhang & Peng, 2011 (see Zhang & Peng 2011: 40, fig. 9) with similar male chelicerae (Fig. 4B) and bulbal apophyses (Fig. 4A) but can be distinguished by presence of large prolateral sclerite distally (arrow 1 in Fig. 3C), bifid prolateral apophysis distally (arrow 2 in Fig. 3C) and small dorsal membranous process distally (arrow 3 in Fig. 3C) on procursus, and by absence of lateral marks on carapace (Fig. 4C), along with the absence of spots on opisthosoma (Fig. 4C).
Description. Male (holotype): Total length 1.80 (1.89 with clypeus), carapace 0.72 long, 0.70 wide, opisthosoma 1.08 long, 0.50 wide. Legs I and III missing, leg II: — (3.00 + 0.30 + 2.68 + – + –), leg IV: 6.83 (1.92 + 0.23 + 1.80 + 2.24 + 0.64). Habitus as in Figs 4 C–E. Carapace and sternum pale, without marks. Legs II and IV pale, without darker rings. Opisthosoma pale, without spots. Distance PME-PME 0.13, diameter PME 0.08, distance PME-ALE 0.03, AME absent. Ocular area not elevated. Thoracic furrow absent. Clypeus unmodified. Sternum slightly wider than long (0.62/0.58). Chelicerae (Fig. 4B) with pair of small proximo-lateral apophyses and pair of long, curved distal apophyses each provided with modified seta on its tip (distance between tips: 0.62). Pedipalps as in Figs 3 A–B; coxa unmodified; trochanter with short retrolatero-ventral apophysis (arrow in Fig. 3A); femur with small dorsal apophysis proximally (arrow in Fig. 3A); procursus (Figs 3 A–D) simple proximally but complex distally, with large prolateral sclerite distally (arrow 1 in Fig. 3C), bifid prolateral apophysis distally (arrow 2 in Fig. 3C) and small dorsal membranous process distally (arrow 3 in Fig. 3C); bulb (Fig. 4A) with long curved apophysis and wide embolus.
