In the Madeira Archipelago, 19 coastal mysid species, five of them new to science, were collected by handnet and by boat operated plankton and bottom nets. These belong to nine different genera, Lophogaster, Siriella, Anchialina, Haplostylus, Erythrops, Leptomysis, Hemimysis, Mesopodopsis, and Heteromysis. So far, 17 coastal mysid species, five of them new to science, were recorded for the Canary Archipelago. These species belong to twelve different genera, Siriella, Anchialina, Gastrosaccus, Haplostylus, Erythrops, Leptomysis, Paraleptomysis, Mysidopsis, Hemimysis, Schistomysis, Paramysis, and Heteromysoides. Two species are known only from the Madeira and Canary islands, four other species appear to be endemic to Madeira, and three more species appear to be endemic to the Canary Islands. 47 % of the Madeiran species were also encountered at the Canary Islands, 53 % of the Canarian species were also recorded for Madeira. Three species were previously regarded as Mediterranean endemics. There is a marked northern influence, in so far as 10 of the 16 'Mediterranean' species are also distributed in boreal to subtropical zones of the NE-Atlantic, extending as far north as the Norwegian coasts. The (sub)tropical Westafrican fauna is represented by two species only, Lophogaster challengeri and Schistomysis sp. A. A new Heteromysis species inhabits gastropod shells occupied by the hermit crab Dardanus callidus; such associations have been recorded from the Red Sea and the Indopacific; for the Atlantic, this is the first record of a mysid shrimp commensal with a hermit crab. A second new Heteromysis species was found only in association with the sea anemone Telmatactis cricoides; similar associations had so far been reported only from the Western Atlantic.
