Etymology.

The specific name is derived from the type locality (Dabashan = Daba Mountain).

Diagnosis.

The new species is similar to C. lichuanensis Wang, Zhou & Peng, 2019 (Wang, Zhou and Peng 2019: 354, figs 5 A – D, 6 A – G) in having similarly shaped retrolateral tibial apophysis, long and strong embolus, posteriorly located epigynal atrium and ball-shaped spermathecae, but differs from the latter by the tegulum with a small process (Figs 3 A, 4 C, D) (vs. without process), the conductor with a short, sclerotic and sharp end (Figs 3 A, B, 4 C – E) (vs. with a long and blunt end in C. lichuanensis) and the anterior edge of atrium unconnected (Figs 3 C, 4 F) (vs. connect in C. lichuanensis).
