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).
