First ingolfiellids from the southwest Pacific (Crustacea: Amphipoda) with a discussion of their systematics

Two new species of ingolfiellid amphipods, Ingolfiella australiana and I. bassiana are described from the continental shelf of Bass Strait, southeastern Australia. Ingolfiella australiana is similar to some species of the subgenus Trianguliella Stock, 1976. Ingolfiella bassiana shows some similarities to species described from the West Indies and the Canary Islands in the subgenus Gevgeliella Karaman, 1959. A re-analysis of sexually dimorphic characters casts doubt on current generic and subgeneric concepts. It is concluded that the ingolfiellidean "eye-lobe" is not homologous with the dorsal pedunculate eyestalk of other peracaridans because of its lateral position.
