A new species of Ischyrocerus (Crustacea: Amphipoda) from Ireland, with a review of Ischyrocerus anguipes and Ischyrocerus minutus from the North-East Atlantic

Abstract

A new species of ischyrocerid amphipod, Ischyrocerus fractus sp. nov., is described from south-west Ireland. An examination of material from the Sars Collection at the Zoologisk Museum, Oslo, has confirmed that Ischyrocerus minutus Sars, previously placed as a synonym of Ischyrocerus anguipes Krøyer, is a valid species and is widespread in the British Isles, while I. anguipes is Arctic/boreal in distribution.

Keywords:
