New calliopiid and eusirid amphipods from eastern Australian waters (Crustacea: Amphipoda: Calliopiidae: Eusiridae)

摘要

The genera Membrilopus, previously known from southern Africa, and Regalia, previously known from the western Indian Ocean, eastern Indonesia and northern New Zealand, are reported for the first time in Australian waters. Three new species-Membrilopus kensleyi, Regalia Juliana and Rhachotropis elliottana-are described. Membrilopus kensleyi is a scavenger living at the base of the continental slope; Regalia Juliana is a sublittoral algal-dweller living along the central eastern Australian coast; and Rhachotropis elliottana occurs off the Great Barrier Reef in depths of 500 m.
