Abstract

In this work, we report for the first time the presence of the amphipod Perioculodes aequimanus from the north-east Atlantic. Specimens were collected in Zostera meadows located in the O grove inlet (north-western Iberian Peninsula), where the species is well established and is one of the numerically dominant peracarid species. Some morphological differences were found in comparison to Mediterranean individuals but those are regarded as due to intraspecific variation. This species can be distinguished from other Atlantic species according to the features of the propodus of the first gnathopod, the first coxa, the pereiopod 7 basis and the antennal peduncle.
