Taxonomy From Gershwin (2006): "I am provisionally keeping C. zygonema in the restricted genus Chiropsalmus because I suspect that C. alipes n. sp. (described below) may hold the key to its identity. This peculiar form from the Pacific coast of southern Mexico is small at maturity, has exumbrellar warts like C. quadrumanus, and has very peculiar carybdeid-like pedalia, such as those described for C. zygonema. Whether the Mexican form and C. zygonema are identical will probably never be known, because there is no known type material of C. zygonema, and Haeckel left no drawings and only a very brief description. I think the most stable course of action is to regard this species as provisionally valid, but to recognize that it is currently represented by an unrecognizable juvenile form, and thus needs to be redescribed based on an adult form from near the type locality."
