Amphipoda from the South Pacific: the Cook Islands

Abstract

Thirty species of gammaridean Amphipoda from 0 to 1.25 m depth are recorded from the Cook Islands. One species, Colomastix murivai n.sp., is new to science and is described and figured. Perioculodes aequimanus (Kossman), recorded for the first time from the Pacific, is also figured along with partial figures of four other species of taxonomic interest. The amphipod fauna of the Cook Islands is most closely similar to that of the Society Islands.
