Attachment of last anal ray to caudal peduncle in Heteroclinus adelaidae and H. macrophthalmus. Considerable confusion has occurred over the identity of Heteroclinus adelaidae and H. antinectes. Whitley (1945) designated a lectotype of Cristiceps antinectes Giinther (1861) and indicated that it was a senior synonym of Petraites phillipi (= H. adelaidae). Although one paralectotype is H. adelaidae, the lectotype and two paralectotypes are of a different and distinct species. Milward (1967) followed Whitley in treating Cristiceps phillipi Lucas as a synonym of Petraites antinectes. However, the species treated by Milward (1967) as P. antinectes is an undescribed species with biserial circumorbital pores not closely related to H. antinectes. Recent sampling has revealed a new species closely related to H. adelaidae from South Australia and Tasmania. The two species treated here are easily distinguished from other Australian clinids by the combination of the two slender pelvic rays, the broad connection of the last anal ray to the caudal peduncle (Fig. 1) and the reduction of the lateral line.
