Taxonomic and faunistic revision of Australian Diaphanosoma (Cladocera : Sididae)

Abstract

Examination of all type material and specimens collected from south-eastern, north-eastern and eastern Australia revealed five Diaphanosoma species in the Australian fauna, one of which is new- D. australiensis. D. excisum and D. unguiculatum are redescribed, and the lectotypes and paralectotypes of these species distinguished. The relationship of the Diaphanosoma fauna in Australia to that of other zoogeographical regions is discussed.
