Summary Fishes of the genus Acanthopagrus are found throughout the coastal waters of Asia and Australia with several species being of commercial significance. In this study, genetic comparisons are made between widely disjunct populations of Acanthopagrus australis (Günther) from Australian and Taiwanese waters and among samples of A. butcheri (Munro), A. berda, (Forskal), A schlegeli (Day) and A. latus (Houttuyn) using mitochondrial DNA sequences obtained from the control region. The mean interspecific pairwise sequence divergence for all species is 17%, while the divergence between A. australis from Australia and that of Taiwan is slightly larger at 18%. These values are considerably higher than those found for intraspecific control region comparisons in some fish species. Phylogenetic analyses indicate that A. australis from Australia is more closely related to the Australian species A. butcheri than to A. australis from Taiwan. These findings suggest that the northern and southern hemisphere forms of A. australis are not monophyletic, with the former possibly representing a new undescribed species of Acanthopagrus.
