The shallow-water gammaridean Amphipoda of the subantarctic islands of New Zealand and Australia: Melitidae, Hadziidae

Abstract

The marine melitid and hadziid amphipods of The Snares, the Auckland Islands, Campbell Island and Macquarie Island are reported from collections made between 1961 and 1980. The number of melitid species known from these islands is increased from 3 to 14. Two new genera and 4 new species are described: Ceradocopsis macracantha, Gammarella hybophora, Hoho hirtipalma and Tagua aporema. All 13 species from The Snares are new records; 5 of the 8 species from the Auckland Islands are new records; all of the 8 species from Campbell Island are new records; and the occurrence of Ceradocopsis kergueleni at Macquarie Island is the first record of a melitid amphipod from that island. A new genus and species of hadziid amphipod, Zhadia subantarctica, is reported from the Auckland Islands.
