The new species can be distinguished from <i>B. shaanensis</i> <b>sp. nov.</b> by 1) size of atrium subequal to posterior epigynal sclerite (Fig. 9A) [vs. obviously larger than posterior epigynal sclerite in the latter (Fig. 15A)]; 2) surface of epigynal pocket smooth, anterior margin membranous (Fig. 9A) [vs. with furrows and with anterior margin sclerotized in the latter (Fig. 15A)]; 3) copulatory ducts connected with spermathecae apically, and the anterior parts of spermathecae most close to each other (Fig. 9B) [vs. connected laterally in the latter, with the posterior parts of spermathecae most close to each other (Fig. 15B)].</p><p><b>Description. Female holotype</b> (Fig. 10). Carapace dark brown. Cervical and radial groove distinct. Cephalic region dark and strongly raised, lateral margin with distinct furrows. Chelicerae with three promarginal teeth and two postmarginal teeth, condyle red. Sternum longer than wide. Abdomen gray, with five chevron-shaped patterns, covered by hairs. Legs reddish brown, metatarsi and tarsi of the first and second legs with normal hairs. Total length 11.48. Carapace 6.67 long, 5.56 wide, cephalic region 4.01 wide. Abdomen 5.94 long, 4.01 wide. Eye size and interdistance: AME 0.20, ALE 0.36, PME 0.25, PLE 0.27; AME–AME 0.16, AME–ALE 0.19, AME–PME 0.19, ALE–PLE 0.08, PME–PME 0.11, PME–PLE 0.47. Leg measurements: Leg I 14.32 (4.26, 1.97, 3.42, 3.09, 1.80), leg II 12.71 (3.72, 1.90, 2.93, 2.81, 1.67), leg III 10.53 (3.07, 1.53, 2.21, 2.58, 1.37), leg IV 14.61 (4.40, 1.80, 3.46, 3.53, 1.66).</p><p>Epigyne (Fig. 9A).
