Lin et al. leg.

Diagnosis.

The male of C. yinzhi is similar to C. ertou but can be distinguished by the nearly straight embolus and the caniniform cymbial tooth, rather than spiraled embolus and hooked cymbial tooth in the latter (Fig. 37A, B vs. Fig. 8A, B ). The female of C. yinzhi is most similar to that of C. thamphra sp. nov. in vulva configuration but differs from the latter by the more widely separated spermathecae and the widely separated inflection points of the copulatory ducts (Fig. 37G vs. Fig. 32G ).

Description.

See Miller et al. (2009).

Distribution.

China (Yunnan) (Fig. 38 ).
