K. Jiang and X. W. Meng leg. GoogleMaps Paratype • 1 ♀ ( SWUC -T-CI-10-02 ), with same data as for holotype ( SWUC) GoogleMaps .

Etymology.

The specific name is derived from the type locality.

Diagnosis.

The new species is similar to C. dabashan sp. nov. (Figs 3 View Figure 3 , 4 View Figure 4 ) in having wide and short retrolateral tibial apophysis, long and strong embolus, strong and beak-like conductor, posteriorly located epigynal atrium and ball-shaped spermathecae, but differs from the latter by the long RTA (Figs 1 B View Figure 1 , 2 Е) (vs. short in C. dabashan sp. nov.), the apical part of conductor as long as the width of conductor base (Figs 1 A, B View Figure 1 , 2 C – E View Figure 2 ) (vs. about half the length of conductor base in C. dabashan sp. nov.) and the oblong atrium (Figs 1 C View Figure 1 , 2 F View Figure 2 ) (vs. somewhat oval in C. dabashan sp. nov.), the short copulatory duct (Figs 1 D View Figure 1 , 2 D View Figure 2 ) (vs. long in C. dabashan sp. nov.).

Palp (Figs 1 A, B View Figure 1 , 2 C – E View Figure 2 ). Femur long, two times longer than cymbium, without modified. Tibia slightly longer than patella. Retrolateral tibial apophysis wide, with a single fold and rounded apex. Base of retrolateral tibial apophysis with two small apophyses, extending ventrally and dorsally. Bulb circular, tegulum semicircular, with a distinct process at middle part in prolateral and ventral view. Sperm duct obvious. Embolus strong, originating at approximately 9 - o’clock position, anterior part resting in the long groove of conductor. Conductor strong, with a sharp end.
