Holotype &amp;male;, Ledong County, Jianfengling Nature Reserve, Mingfeng Valley, 18°44.485′N, 108°50.812′E, elev. 960 m, 28.III.2015, L.Y. Wang &amp; G.Q. Huang leg. (SWUC). Paratypes. 9&amp;male; 13&amp;female;, same data as holotype (SWUC); 2&amp;male; 4&amp;female;, Jianfengling Nature Reserve, Wufengqu, 18°44.415′N, 108°51.802′E, elev. 900 m, 18 May 2011, Y.Y.

Carapace 2.52 long, 1.70 wide; opisthosoma 2.85 long, 1.71 wide. Eye sizes and interdistances: AME 0.05, ALE 0.06, PME 0.26, PLE 0.20; AME–AME 0.05, AME–ALE 0.10, PME–PME 0.15, PME–PLE 0.21. Clypeus height 0.08. Leg measurements: I 4.97 (1.43, 1.70, 1.12, 0.72); II 4.66 (1.32, 1.56, 1.11, 0.67); III 4.61 (1.30, 1.53, 1.19, 0.59); IV 6.55 (1.74, 2.07, 1.85, 0.89). Leg formula: 4123.
