Type material.
Holotype • ♂ ( SWUC -T-THO-03-01 ), China, Xizang, Medog County, Beibeng Township, Damu , 29°14'51"N, 95°11'1"E, elev. 924 m, 28 June 2018, L. Y. Wang, Y. N. Mu and Z. S. Wu leg. GoogleMaps Paratype: • 1 ♀ ( SWUC -T-THO-03-02 ), same data as for holotype GoogleMaps .
Etymology.
The specific name is derived from the type locality; it is a noun in apposition.
Diagnosis.
The new species resembles S. liae Tang, Yin, Griswold & Peng, 2006 ( Tang et al. 2006: 65, figs 1–13) in having a similar shaped retrolateral tibial apophysis, but it differs from the latter by the retrolateral tibial apophysis which is shorter than the bulb (vs equal in length to the bulb in S. liae ), the long, thin apical tegular apophysis (vs short and wide in S. liae ), and the C-like spermathecae (vs caterpillar-like in S. liae ) (Fig. 7 View Figure 7 ). This new species also resembles S. dawai Wang, Lu & Zhang , sp. nov.; see diagnosis for S. dawai .

Opisthosoma oval, yellow, with a black spot. Spinnerets brown.
Palp (Fig. 7 A, B View Figure 7 ). Tibia longer than wide. Ventral tibial apophysis small, thumb-shaped, near retrolateral tibial apophysis. Retrolateral tibial apophysis four times longer than ventral tibial apophysis, jellyfish-shaped in retrolateral view. Dorsal tibial apophysis small, conical. Bulb flat, apical tegular apophysis thin and long. Embolus filiform, originating at approximately 6 - o’clock position, curved along with bulb, tip staying in cymbial furrow.
Female paratype ( SWUC -T-THO-03-02 , Fig. 3 F View Figure 3 ) total length 4.86. Prosoma 2.37 long, 2.17 wide; opisthosoma 2.48 long, 2.32 wide. Eye sizes and interdistances: AME 0.08, ALE 0.19, PME 0.02, PLE 0.16; AME – AME 0.23, AME – ALE 0.26, PME – PME 0.26, PME – PLE 0.52, ALE – PLE 0.23. MOA 0.26 long, anterior width 0.40, posterior width 0.32. Clypeus height 0.25. Leg measurements: I 6.90 (2.13, 2.60, 1.26, 0.91); II 7.16 (2.24, 2.62, 1.30, 1.00); III 4.85 (1.56, 1.87, 0.70, 0.72); IV 4.81 (1.60, 1.73, 0.81, 0.67). Leg formula: 2134.
Epigyne (Fig. 7 C, D View Figure 7 ). Epigynal plate as long as wide. Copulatory openings slit-like, distant from each other. Copulatory ducts S-like. Spermathecae C-shaped. Fertilization ducts crescent-shaped.
