Distribution. China (Zhejiang, Fujian, Jiangxi, Taiwan, Guizhou, Guangxi).

Discussion. This species is very similar to C. armatus . The first antennal joint is flat above with sides forming a kind of ridge, and therefore it belongs to Cordax . Cordax unidentatus appears to be widely distributed in China. It shows great variation in the shape of male forceps. The descriptions of T. inermis from Guizhou and T. cuneatus from Guizhou only differ from C. unidentatus in minute differences that fall well within the variational limits of the latter; therefore, both are considered synonyms of C. unidentatus .
