Etymology. The specific epithet is an adjective in apposition derived from the type locality.

Diagnosis. Male of S. damingshanensis sp. nov. resembles S. zhuangius sp. nov. ( Figs 3–4 ), but can be distinguished from the latter by the following characters: three arms of median apophysis (AA, RA and PA) protruded, AA with several teeth ( Figs 1A , 2D, F , arms of median apophysis small and AA without teeth in the latter species, Figs 3A , 4E ); the sclerotized terminal apophysis (TA2) flame-shaped, slightly curved ( Figs 1A, C , 2D–H ), (villusshaped in the latter one ( Figs 3 , 4D–E ). Epigyne of the new species can be distinguished from other lycosids by a tongue-shaped septum, the compact spermathecal stalks and round spermathecal heads ( Figs 1D–E , 2I–J ).

Description. Male. Total length 4.80–5.20. Holotype ( Figs 2A, 2C ) total length 4.80. Carapace 2.59 long, 1.92 wide; opisthosoma 2.17 long, 1.45 wide. Eye sizes and interdistances: AME 0.08, ALE 0.08, PME 0.33, PLE 0.23; AME–AME 0.10, AME–ALE 0.10, PME–PME 0.25, PME–PLE 0.29. Clypeus 0.17 high. Leg measurements: I 7.52 (1.96, 2.54, 1.98, 1.04); II 6.61 (1.84, 2.16, 1.72, 0.89); III 6.18 (1.73, 2.01, 1.62, 0.82); IV 8.90 (2.37, 2.82, 2.56, 1.15).

Pedipalp ( Figs 1A – C , 2D – H ). Median apophysis with three arms, AA, PA and RA. Embolus long and slender, its anterior part resting in a long groove of a large and complex terminal apophysis. Terminal apophysis with two arms, one of them membranous, as the functional conductor, the other one sclerotized and groove-like.

Female (SWUC-T-LY-06-02, Fig. 2B ) total length 6.15. Carapace 2.61 long, 1.83 wide; opisthosoma 3.34 long, 2.23 wide. Eye sizes and interdistances: AME 0.08, ALE 0.06, PME 0.34, PLE 0.25; AME–AME 0.08, AME–ALE 0.13, PME–PME 0.26, PME–PLE 0.27. Clypeus 0.16 high. Leg measurements: I 7.80 (2.17, 2.84, 1.82, 0.97); II 7.32 (2.06, 2.47, 1.79, 1.00); III 6.88 (1.96, 2.17, 1.89, 0.86); IV 10.04 (2.67, 3.37, 2.81, 1.19). Abdomen dorsum yellowish brown, with lanceolate cardiac mark in anterior half continuing into black irregular markings extending posteriorly. Venter of abdomen yellow, with small yellow spinnerets.

Female genitalia ( Figs 1D – E , 2I –J ). Copulatory openings arc-shaped. Septum broad and tongue-shaped, the base is wider and tapered posteriorly. Spermathecal stalks compact and sclerotized, both are separated from each other by 1/3 distance of their radius. Spermathecal heads small with round end. Fertilization ducts crescent.

Distribution. Known only from around the type locality, Mt. Daming area, Guangxi of China ( Fig. 11 ).
