A revision of the taxonomy of the gennus Daphnia (Crustacea : Daphnidae) in south-eastern Australia

The taxonomy of Daphnia in south-eastern Australia has been revised on the basis of conventional morphological studies supplemented by electrophoretic analysis. Ten species are recognized; of these five have not previously been described and three others have been treated as forms of Daphnia carinata. Detailed descriptions, with figures of the females of all species and of the males of eight species, are included as well as a key to the adult females. Comment is made on the ecology and distribution of the species and on the zoogeographical relationship of Australian Daphnia.
