The genus Syrrhoe (Crustacea, Amphipoda, Synopiidae) from the North Atlantic

Abstract

Three species of the amphipod genusSyrrhoeare described from the North Atlantic. The differences between these species are primarily the patterns of serration of the posterior margins of pleonite 3 and urosomite 1 and 2:Syrrhoeaffinishas a wide convex space on the posterior margin between the epimeron 3 and the dorsal serration. InSyrrhoecrenulataandSyrrhoeanneheleneaesp. nov.there is only a small notch on the posterior margin of pleonite 3.Syrrhoeanneheleneaesp. nov., otherwise similar toS.crenulata, has an additional serration on the posterior margin of urosomite 1. The inter- and intraspecific distances analyzed from COI confirm the morphological species concept of North AtlanticSyrrhoe.
