Discussion. This species was described by Burr, 1917 in the genus Kosmetor . Steinmann (1989) transferred it to the genus Pterygida . The first antennal joint is flat above with sides forming a kind of ridge, and therefore it should belong to the genus Cordax . Eutimomena paradoxa Bey-Bienko, 1970 was synonymized with Cordax armatus ( Haan, 1842) by Srivastava (1987), but on the basis of its original description it appears to be identical to C. claviger . Therefore, we propose E. paradoxa as a junior subjective synonym of C. claviger .
