Etymology
The species name is derived from the name of the type locality; adjective.
Diagnosis
Similar to Cosmophasis courti Żabka & Waldock, 2012 (Żabka and Waldock 2012[1]: figs 52A–H, 53A–D), but tibia is subequal to cymbium (Fig. 19A–B) vs. twice as long in Cosmophasis courti, RTA with one small apical hook (Fig. 19B), lacking in Cosmophasis courti. Copulatory openings widely separated (Fig. 20A), about three diameters vs. only 1/4 the diameter of a copulatory opening.
Description
Male (holotype). Total length 5.20, CL 2.30, CW 1.72, AL 2.90, AW 1.05. Eye measurements: AME 0.55, ALE 0.24, PME 0.05, PLE 0.20, AER 1.59, PER 1.59, EFL 1.44. Clypeus 0.09 high. Legs: I 4.34 (1.34, 0.94, 1.00, 0.56, 0.50); II 3.64 (1.13, 0.70, 0.76, 0.58, 0.47); III 3.84 (1.30, 0.55, 0.71, 0.80, 0.48); IV 4.31 (1.41, 0.56, 0.70, 1.06, 0.50).
Carapace dark brown (Fig. 20C). Chelicerae dark brown, sparsely covered with fine grey hairs. Maxillae brown with light tips and grey hairs on inner margins. Labium brown, tip with black hairs. Abdomen light, with irregular black patches. Venter and spinnerets dark grey. Legs I more robust and darker than others. Spination of leg I: femur d2-1-0; tibia v2-2-2; metatarsus v2-0-2. Palpal tibia white, subequal to the cymbium. The apophysis short, about 1/4 the length of the cymbium, with a small apical hook (Fig. 19B). Embolus starting at the prolateral part of the bulb, bent (Fig. 19C).
Female (same locality of holotype). Total length 6.46, CL 2.66, CW 1.90, AL 3.80, AW 1.64. Eye measurements: AME 0.60, ALE 0.22, PME 0.06, PLE 0.22, AER 1.59, PER 1.59, EFL 1.44. Clypeus 0.08 high. Legs: I 4.34 (1.34, 0.94, 1.00, 0.56, 0.50); II 3.64 (1.13, 0.70, 0.76, 0.58, 0.47); III 3.84 (1.30, 0.55, 0.71, 0.80, 0.48); IV 4.31 (1.41, 0.56, 0.70, 1.06, 0.50).
Carapace yellow (Fig. 20D). Abdominal venter grey-white. Legs yellowish. Spination of leg I: femur d2-1-0; tibia v2-2-2; metatarsus v2-0-2. Other characters similar to those of male. Epigynal plate weakly sclerotized. Copulatory opening grooves with sclerotised edges, openings widely separated (about three diameters). Posterior margin projecting in midline (Fig. 20A). Copulatory ducts broad, located posteriorly. Receptacles round, strongly sclerotised. Fertilisation ducts elongate, located at the anterior part of the receptacles (Fig. 20B).
Distribution
Known from several localities in Xishuangbanna.
