Review of the Australian fish family Arripididae (Percomorpha), with the description of a new species

Abstract

The family Arripididae contains one genus, Arripis Jenyns, with four species endemic to areas within temperate Australian and New Zealand waters. A. georgianus (Valenciennes), found throughout cool temperate Australia, is identified by having more than 27 rakers on the lower limb of the first gill arch. A. truttaceus (Cuvier), found in Western and South Australia, Victoria and Tasmania, has fewer than 17 rakers on the lower limb of the first gill arch. A. trutta (Bloch & Schneider), found in eastern Australia, Victoria, Tasmania and New Zealand, has 20-24 rakers on the lower limb of the first gill arch and a small caudal fin whose length is equal to or less than the length of the head. A. xylabion sp, nov., found in northern New Zealand, Lord Howe Island, Norfolk Island and the Kermadec Islands, is identified by having 20-25 rakers on the lower limb of the first gill arch and a large caudal fin whose length is longer than that of the head. A neotype is designated for A. trutta.
