Bogdocosa multivaga is similar to B. flavida and B. yunshani sp. nov. in having a pair of epigynal lobes (Figs 8 D, 10 C; 1 B, 2 D, 4 C; 11 D, 13 C), but can be distinguished by ventral arm of median apophysis digitiform ventrally in B. multivaga (Figs 8 B, 9 B, D, G, 14 C) (vs. rod-shaped in B. flavida, Figs 2 B, 3 B, D, G, 14 A; sectorial in B. yunshani sp. nov., Figs 11 B, 12 B, D, G, 14 D). Females can be distinguished by interlobar space narrower than lobe width with individual lobes 1.5 times as wide as long in B. multivaga (Figs 8 D, 10 C) (vs. two epigynal lobes closely approximated with individual lobes 2 times as wide as long in B. flavida, Figs 1 B, 2 D, 4 C; interlobar space equal to lobe width and individual lobes as wide as long in B. yunshani sp. nov., Figs 11 D, 13 C). Description. Male (Fig. 10 A) total length 6.13. Prosoma 3.19 long, 2.28 wide; opisthosoma 2.99 long, 1.99 wide. Eye sizes and interdistances: AME 0.12, ALE 0.10, PME 0.28, PLE 0.24; AME – AME 0.08, AME – ALE 0.03, PME – PME 0.17, PME – PLE 0.21. Clypeus height 0.18. Leg measurements: I 7.97 (2.16, 2.67, 1.89, 1.25); II 7.30 (2.02, 2.39, 1.75, 1.14); III 7.19 (1.95, 2.28, 1.88, 1.08); IV 11.25 (2.88, 3.44, 3.46, 1.47). Palp (Figs 8 A – C, 9 A – G, 14 C). Terminal apophysis hook-shaped, with short and thick end. Prolateral arm of median apophysis sclerotized. Ventral arm of median apophysis digitiform and narrower than retrolateral arm of median apophysis ventrally. Embolus bent into a human-ear-shape in ventral view. Lobe of embolic base with arc-shaped end. Conductor with two bifurcations. Female (Fig. 10 B) total length 7.80. Prosoma 3.33 long, 2.45 wide; opisthosoma 4.66 long, 2.77 wide. Eye sizes and interdistances: AME 0.12, ALE 0.10, PME 0.29, PLE 0.24; AME – AME 0.09, AME – ALE 0.06, PME – PME 0.20, PME – PLE 0.28. Clypeus height 0.15. Leg measurements: I 8.07 (2.33, 2.72, 1.85, 1.17); II 7.14 (2.11, 2.32, 1.63, 1.08); III 7.76 (2.08, 2.42, 2.09, 1.17); IV 12.26 (3.20, 3.57, 3.92, 1.57). Epigyne (Figs 8 D, E, 10 C, D). Epigynal lobes equal in length and width. Interlobar space narrower than lobe width. Median plate trapezoid, as long as wide. Copulatory openings located on lateral margins of median plate. Spermathecal heads circular. Distribution. China (Beijing, Inner Mongolia, Ningxia, Gansu, Shaanxi, Shanxi, Hebei, Shandong) (Fig. 16).
