Etymology.

The specific name refers to the type locality.

Diagnosis.

This new species is similar to C. lichuanensis Wang, Zhou & Peng, 2019 ( Wang et al. 2019: figs 5 A – D, 6 A – G) in having the similar shaped retrolateral tibial apophysis, the long and strong embolus, the posteriorly located epigynal atrium, and the ball-shaped spermathecae, but differs by the wider and slightly curved retrolateral tibial apophysis (Figs 4 B View Figure 4 , 5 E View Figure 5 ) (vs. wide and more curved in C. lichuanensis ), the sharp conductor end (Figs 4 A, B View Figure 4 , 5 C – E View Figure 5 ) (vs. blunt in C. lichuanensis ), and the wide epigynal atrium (Figs 4 C, D View Figure 4 , 5 F, G View Figure 5 ) (vs. wider in C. lichuanensis ).
