Material examined.

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. 10 G, I ) vs. with two spinelike processes ( Baehr and Ubick 2010: figs 161–163), and long copulatory duct (cd, Fig. 11 H, 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. 9 A, C, E ; length 1.91. Carapace (Fig. 9 B, F ): 0.85 long, 0.78 wide; pars thoracica strongly elevated in lateral view, whole surface finely reticulated. Eyes (Fig. 9 B, 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. 9 F, G ): margin unmodified, straight in front view, sloping forward in lateral view. Mouthparts (Fig. 9 D, G ): chelicerae unmodified; anterior-median part of the endites slightly sclerotized. Sternum (Fig. 9 D ): as long as wide, with pointed anterolateral bumps. Abdomen (Fig. 9 A, 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. 10 A – 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).

Female ( SYNU -1142 ). As in male except for the following. Body: habitus as in Fig. 11 A, C, E ; length 2.37. Carapace: 0.92 long, 0.81 wide. Eyes: ALE 0.07; PME 0.05; PLE 0.05. Abdomen: 1.45 long, 0.90 wide. Postgaster (Fig. 11 F, H ): with rounded anterior sclerite (as) and pear-shaped median plate (mp). Endogyne (Fig. 11 I ): copulatory duct (cd) long, narrow, straight with tip reaching groove between posterior spiracles; apodemes (ap) short.

Etymology.

The specific name refers to the type locality and is a noun in apposition.

Distribution.

Known only from the type locality.
