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.

Etymology.

The specific name is named in honor of the collector, Mr Guo Zheng.

Distribution.

Known only from the type locality.
