Type material.

Holotype • ♂ ( SWUC -T-LY-27-01 ): China, Xinjiang, Changji, Hutubi Co., No. 6 Reservoir , 26May2023, 44°17'26"N, 86°56'47"E, elev. 455 m, Y. S. Yang leg. Paratypes • 2 ♂ 3 ♀ ( SWUC -T-LY-27-02 to 06), with same data as holotype .

Etymology.

The specific name is a patronym honouring Mr. Yunshan Yang who collected this new species.

Diagnosis.

Bogdocosa yunshani sp. nov. is similar to B. flavida and B. multivaga in having a pair of epigynal lobes (Figs 11 D , 13 C ; 1 B , 2 D , 4 C ; 8 D , 10 C ), but differ by ventral arm of median apophysis approximately sectorial ventrally in B. yunshani sp. nov. (Figs 11 B , 12 B, D, G , 14 D ) (vs. rod-shaped in B. flavida , Figs 2 B , 3 B, D, G , 14 A ; digitiform in B. multivaga , Figs 8 B , 9 B, D, G , 14 C ). Females can be distinguished by interlobar space equal to lobe width and individual lobes as wide as long in B. yunshani sp. nov. (Figs 11 D , 13 C ) (vs. two 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 1.5 times as wide as long in B. multivaga , Figs 8 D , 10 C ).

Leg measurements: I 7.96 (2.27, 2.84, 1.56, 1.29); II 7.53 (2.14, 2.50, 1.65, 1.24); III 7.61 (2.19, 2.26, 2.00, 1.16); IV 12.06 (3.04, 3.67, 3.79, 1.56).

Epigyne (Figs 11 D, E , 13 C, D ). Epigynal lobes as long as wide. Interlobar space equal to lobe width. Median plate trapezoid, longer than wide. Copulatory openings situated on lateral margins of median plate. Spermathecal heads circular.

Variation.

Males (n = 3) total length 5.09–5.44, females (n = 3) total length 6.62–8.05.
