The family Aristiidae (Crustacea: Amphipoda: Lysianassoidea) in Australian waters

摘要

The lysianassoid amphipod family Aristiidae is reported from Australian waters for the first time. Two new genera and seven new species are described: Aristias eden sp. nov.; A. gomoni sp. nov.; A. nowra sp. nov.; A. otway sp. nov.; A. poorei sp. nov.; Memana sarda gen. nov., sp. nov.; and Pratinas ludmilla gen. nov. sp. nov. The lysianassoid amphipod family Aristiidae is a world-wide group of about 30 species not previously reported from Australian waters. The geographically closest records are those of Aristias tropicus Schellenberg, 1938 from Papua New Guinea, A. thio Lowry & Stoddart, 1994 and A. uokonia Lowry & Stoddart, 1994 both from New Caledonia and an unnamed species of Aristias from New Zealand (Rainer 1981). In this paper we describe seven new species in the genera Aristias Boeck, 1871, Memana gen. nov. and Pratinas gen. nov. All but one of the new taxa come from south-eastern Australia.
