Abstract

Five species of Erythropinae are described from the Iceland Basin. Amblyops trisetosa and A. spinifera are shown to have extended their species range from the Bay of Biscay to Iceland. Pseudomma maasaki and P. islandicum are described as new species. A full description of P. antarcticum, previously reported only from Antarctic waters, is presented, including a first description of the male pleopods. The extended northward distribution of the previously described species coupled with P. islandicum bearing close resemblance to Antarctic Pseudomma species indicates the absence of dispersal barriers for bottom-living mysids in the Atlantic deep sea east of the mid-Atlantic Ridge.
