Three species of the amphipod genus Syrrhoe are 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: Syrrhoe affinis has a wide convex space on the posterior margin between the epimeron 3 and the dorsal serration. In Syrrhoe crenulata and Syrrhoe anneheleneae sp. nov. there is only a small notch on the posterior margin of pleonite 3. Syrrhoe anneheleneae sp. nov., otherwise similar to S. 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 Atlantic Syrrhoe.
