Etymology. The specific name is a patronym in honor of Mr. Zhi-Yuan Yao (IZCAS), who took part in the field work in 2009.

Diagnosis. This new species is very similar to S. hupingensis Tang, Peng and Yin, 2004 from Hunan Province, but can be separated from the latter by: cymbium with a dorsal outgrowth (absent in S. hupingensis ); ratio of length of RTA / VTA = 0.5 (about 1.0 in S. hupingensis ). This new species can be separated from S. schwendingeri by: 1) opisthosoma oval (elongated in S. schwendingeri ); 2) RTA sharp (bifurcate in S. schwendingeri ); 3) RTA uncovered by tutaculum (covered in S. schwendingeri ).

Description. Male (holotype measured): Total length 2.40. Prosoma 1.05 long, 0.95 wide; opisthosoma 1.30 long, 0.97 wide. Dorsal shield of prosoma dark brown. Prosoma with conspicuous crest of four projections, the two posterior ones bifurcate. Eye tubercles large; an angle-shaped projection presented between ALE and PLE. Eye measurements: AME 0.06; ALE 0.14; PME 0.05; PLE 0.13; AME–AME 0.12; AME–ALE 0.08; PME–PME 0.25; PME–PLE 0.22. MOA length 0.34 with front width 0.24 and back width 0.37. Chelicerae, gnathocoxae, labium and sternum dark brown; chelicerae with one large and one small promarginal teeth. Legs slender, femora with blackish brown annuli, each femur with a dorsal spine. Leg measurements: I: 2.82 (0.90, 1.00, 0.52, 0.40); II: 2.85 (0.90, 1.00, 0.55, 0.40); III: 2.35 (0.70, 0.80, 0.50, 0.35); IV: 2.68 (0.88, 0.90, 0.55, 0.35), leg formula: 2143. Opisthosoma oval, dorsally blackish brown with a pair of brown stripes, venter grayish brown.
