The Australian species of Diaptomus (Copepoda: Calanoida) and their distribution

Abstract

The species Diaptomus (Eodiaptomus) lumholtzi Sars and D. (Tropodiaptomus) australis (Kiefer) are redescribed and figured. Both species are recorded from numerous new localities in northern Australia. The southern limit of distribution of D. lumholtzi is discussed in relation to the northern limit of Boeckella. A single example of the coexistence of D. lumholtzi with Boeckella triarticulata, and three examples of coexistence of D. lumholtzi with Calamoecia are cited.
