Material examined.

Holotype China • ♂ ( SYNU -1134 ); Xizang, Nyingchi , nr. Metok Co.; 29 ° 19.382 ' N, 95 ° 19.016 ' E, 980 m; 2. VIII. 2013; Y. Lin leg.

Paratype: China • ♂ ( SYNU -1135 ); same data as for holotype, Motuo Petrol Station ; 22. IX. 2013; Z. Gao leg.

Diagnosis.

This new species is similar to C. linyejiei Tong & Li, 2021 , but can be distinguished by their normal-sized eyes (Fig. 1 B, G ) vs. reduced ( Huang et al. 2021: fig. 4 B, G); and the thread-like structure (tls) on the tip of the psemblous (Fig. 2 G, H ), vs. lacking; and having a plate-like process ( Huang et al. 2021: fig. 5 G, H).

Description.

Male (holotype). Body: uniformly colored, yellow; habitus as in Fig. 1 A, C, E ; length 1.29. Carapace (Fig. 1 B, F ): 0.66 long, 0.54 wide; pars thoracica strongly elevated in lateral view, entire surface finely reticulated. Eyes (Fig. 1 B, G ): ALE: 0.05; PME: 0.04; PLE: 0.04; ALE circular, PME oval, PLE oval; posterior eye row procurved from both above and front; ALE separated by less than one radius. Clypeus (Fig. 1 F, G ): margin unmodified, straight in front view, sloping forward in lateral view. Mouthparts (Fig. 1 D, G ): chelicerae unmodified; anterior-median part of endites strongly sclerotized. Sternum (Fig. 1 D ): as long as wide, with pointed anterolateral bumps. Abdomen (Fig. 1 A, C, E ): 0.63 long, 0.34 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 covering about 3 / 4 of abdominal venter. Palp (Fig. 2 A – K ): reddish brown; patella extremely long club-shaped, length / width = 3.04, about 5.6 times longer than femur, and 2.5 times longer than bulb; cymbium narrow (length / width = 1.68) in dorsal view; distal part of bulb with narrow process (np), broad ventral outgrowth (vo), a narrow wing-like outgrowth (wlo), a small retrolateral fold (rlf) and cluster of thread-like structure (tls).

Female. Unknown.

Notes.

Seven species [ C. glenniei (Fage, 1946) from India, C. martensi Baehr, 2010 , C. panchthar Baehr, 2010 , C. silens Brignoli, 1976 , C. strepens Brignoli, 1976 and C. taplejung Baehr, 2010 from Nepal and C. gunsa Baehr, 2010 from India and Nepal] in adjacent areas are known only from females and this new species can be potentially conspecific with one of them.

Etymology.

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

Distribution.

Known only from the type locality.
