Some Ergasilids (Copepoda) parasitic on four species of Australian bream, Acanthopagrus spp

Abstract

Four ergasilid species are recorded from Australian bream, i.e. Acanthopagrus butcheri (Munro), A. australis (Gunther), A. berda (Forskill) and A. latus (Houttuyn) from around Australia. New species include Dermoergasilus acanthopagri and Ergasilus spinipes. Previously described species include E. lizae Krmyer and Paraergasilus acanthopagri Roubal. Ergasilus australiensis Roubal is synonymized with E. lizae. The zoogeography and host specificity of parasites are described.
