Holotype China • ♂ (SYNU-1141); Xizang, Zayu Co., Chawalong Town, Long Vill.; 28°28.941'N, 98°28.193'E, 2883 m; 8.IX.2014; J. Liu leg.

Paratypes. China • 1 ♀ (SYNU-1142); same data as for holotype.

Diagnosis.

The new species is similar to the type species, C.fulva Caporiacco, 1934, but can be distinguished by the strongly sclerotized dorsal (dp) and ventral (vp) processes of the psembolus (Fig. 10G, I) vs. with two spinelike processes (Baehr and Ubick 2010: figs 161–163), and long copulatory duct (cd, Fig. 11H, I) vs. short inverted droplet-shaped copulatory duct (Baehr and Ubick 2010: figs 182, 183).

Description.

Male (holotype). Body: uniformly colored, pale yellow; habitus as in Fig. 9A, C, E; length 1.91. Carapace (Fig. 9B, F): 0.85 long, 0.78 wide; pars thoracica strongly elevated in lateral view, whole surface finely reticulated. Eyes (Fig. 9B, G): ALE: 0.08; PME: 0.06; PLE: 0.06; ALE circular, PME oval, PLE oval; posterior eye row procurved from both above and front; ALE separated by less than one radius. Clypeus (Fig. 9F, G): margin unmodified, straight in front view, sloping forward in lateral view. Mouthparts (Fig. 9D, G): chelicerae unmodified; anterior-median part of the endites slightly sclerotized. Sternum (Fig. 9D): as long as wide, with pointed anterolateral bumps. Abdomen (Fig. 9A, C, E): 1.06 long, 0.68 wide; oval, scuta pale orange; dorsal scutum covering about 5/6 of abdomen length, about 3/4 of abdomen width, fused to epigastric scutum; postgastric scutum small, covering about 1/2 of abdominal venter. Palp (Fig. 10A–K): reddish brown; patella extremely long club-shaped, length/width = 2.96, about 4.2 times longer than femur, and 2.5 times longer than bulb; cymbium narrow (length/width = 1.64) in dorsal view; psembolus with strongly sclerotized dorsal process (dp), strongly sclerotized ventral process (vp), broad ventral outgrowth (vo) and a small retrolateral fold (rlf).
