Chelicerae, endites and labium yellow brown, apices of endites and labium yellowish. Sternum brown, lateral margin slightly dark. Legs brown. Dorsum of opisthosoma with a pair of anterior patches, followed by three transverse median bands and pre-anal spot; venter yellowish. Spinnerets yellowish.

Prosoma ( Fig. 8 ). Carapace longer than wide, thorax swell, tegument smooth and shiny. Both the eye rows procurved in dorsal view. Diameters of eyes: AME 0.05, ALE 0.05, PME 0.07, PLE 0.08. Interdistances of eyes: AME–AME 0.02, AME–ALE 0.03, ALE–ALE 0.36, PME–PME 0.07, PME–PLE 0.11, PLE–PLE 0.48, ALE–PLE 0.09. MOA 0.27 long, front width 0.18, back width 0.21. Clypeal height 0.32. Fangs of chelicerae short. Labium triangular, 0.27 long, 0.23 wide. Sternum 0.59 long, 0.50 wide and furnished with sparse black setae.

Legs. Each femur with a dorsal spine. Measurements of legs: I: 3.34 (0.90, 0.27, 0.77, 0.86, 0.54), II: 2.44 (0.68, 0.27, 0.45, 0.59, 0.45), III: 2.75 (0.72, 0.27, 0.50, 0.81, 0.45), IV: 3.84 (0.95, 0.32, 0.81, 1.22, 0.54). Leg formula: 4132.

Opisthosoma ( Fig. 8 ). Oval, longer than wide, covered with short, black hairs, without dorsal scutum.

Female genitalia ( Figs 9–11 ). Copulatory openings situated in median part of epigynum; long and winding copulatory ducts visible through integument; spermathecae situated posteriorly, small, long oval and partly hidden in copulatory ducts.

Distribution. China (Hainan).
