A new acanthocolpid, Tormopsolus attenuatus n. sp., is described from the carangid Seriola hippos from waters off the coast of SW Australia. A cladistic analysis of the genus using 31 morphological and metrical characters indicates that the closest species is T. asiatica Parukhin, 1976 status amend. (previously T. orientalis asiatica). T. attenuatus differs from T. asiatica in its smaller overall dimensions, more attenuated outline, relatively shorter post-testicular region, vitelline interruption at the level of the ovary, papillae on the oral sucker and, possibly, much longer genital atrium. Other similar species, T. orientalis Yamaguti, 1934 and T. medius Reimer, 1983, differ in having interruptions of the vitelline fields at the level of both testes and at the level of the ovary.
