Aega komai, a new species of marine isopod crustacean (Aegidae: Flabellifera) from Japan

Abstract

Aega komai sp. nov. from Japanese waters, is described and figured from the single known specimen. Brief comments are given on the relationship of Aega komai sp. nov. to other species of the genus. The species is characterised by the plate-like expansion of antennule articles 1 and 2, the flattened and expanded antenna article 5, short, truncate and deeply serrate pleotelson, together with deeply serrate uropods, and the presence of a conspicuously large spine of pereopod 3 only.
