The specific name refers to the type locality, which is a noun in apposition.

Diagnosis.

The new species resembles B. halongensis Yao, Pham & Li, 2015 (Yao et al. 2015: 8, figs 16 A – D, 17 A – D, 18 A – D) by having similar male chelicerae and bulbal apophyses (Fig. 15 A, B), but can be distinguished by differences in males: procursus with two sclerotized distal apophyses (arrows in Figs 14 C, 19 A vs one prolatero-ventral sclerite), retrolateral flap (Figs 14 D, 19 B vs absent) and without prolatero-distal membranous lamella (Figs 14 C, 19 A vs present).
