Diagnosis.
The new species can be distinguished from all the congeners in having the eyes not reduced (Figs 1 D, 2 G), vs reduced eyes (Tong and Li 2015: figs 1 F, 3 D, 4 C, 5 D; Sun et al. 2019: fig. 1 H). Furthermore, males of the new species can be distinguished from those of B. crassispina and B. parvula by the short comb-like structure on dorsal branch of bulb and group of thick setae on epigastric region (Figs 1 G, 4 F), vs without comb-like structure and group of thick setae (Tong and Li 2015: figs 1 G, 2 E, 4 F, 6 A); females of the new species can be distinguished from those of B. crassispina, B. parvula, and B. songxiaobini by the posterior spiracles not connected by groove (Figs 2 H, 3 D), vs connected (Tong and Li 2015: figs 3 G, H, I, 5 G; Sun et al. 2019: fig. 1 G).
Description.
Male (holotype). Body yellow, chelicerae, sternum, and legs lighter; habitus as in Fig. 1 A, C, E; body length 1.45. Carapace (Fig. 1 B, F): 0.68 long, 0.50 wide; pars cephalica almost flat in lateral view, surface smooth. Eyes (Fig. 1 B, D): ALE largest; PLE and PME nearly equal in size; ALE – PLE separated by less than ALE radius; PME touching each other; posterior eye row recurved as viewed from above, straight as viewed from front. Clypeus (Fig. 1 D): height about 0.5 times of ALE diameter, with a triangular clypeus median projection (cmp). Mouthparts (Fig. 3 C): labium deeply incised. Sternum (Fig. 1 G): surface finely reticulate. Abdomen (Fig. 1 A, C, E, G): 0.82 long, 0.45 wide; dorsal scutum nearly covering full length of abdomen, postepigastric and epigastric scutum fused, covering 5 / 6 of abdomen length; book lung covers ovoid, surface smooth; epigastric region with a group of thick setae, posterior spiracles not connected by groove. Palp (Figs 3 A, B, 4 A – G): pale-orange; 0.48 long (0.15, 0.09, 0.08, 0.16); femur elongated (width / length = 0.48); bulb oval, tapering apically; embolus system complicated, with a cluster of short comb-like structures on dorsal branch, many hair-like structure on ventral and posterior branches.
Female (SYNU - 1053). Same as male except as noted. Body habitus as in Fig. 2 A, C, E; body length 1.51. Carapace (Fig. 2 B, F): 0.66 long, 0.53 wide. Abdomen (Fig. 2 A, C, E, H): 0.84 long, 0.56 wide; dorsal scutum covering about 4 / 5 of abdomen length, about 2 / 3 of abdomen width; postepigastric scutum rectangular, posterior margin nearly straight. Epigaster (Fig. 3 D): surface without external features. Endogyne (Fig. 3 E): with two narrow, transverse sclerites (tsc) and an anterior stick-shaped sclerite (as); lateral apodemes (ap) present.
