Eight species of the suborder Anthuridea (Crustacea, Isopoda) were collected in the northernmost part of the North Atlantic and in the Arctic Ocean during the BIOICE project. Two species were new to science: Haliophasma mjoelniri sp. nov. found at depths between 340 and 508 m west ofIceland, and Quantanthura tyri sp. nov. at depths between 304 and 1212 m south-west and west ofIceland. Other species found were Ananthura sulcaticauda Barnard, 1925, Calathura brachiata (Stimpson, 1853), Leptanthura affinis (Bonnier, 1896), L. chardyi Negoescu, 1992, L. micrura Kensley, 1982, and L. victori Negoescu, 1985. All eight species were found in the North Atlantic Ocean, and only Ananthura sulcaticauda and Calathura brachiata were additionally found in the Arctic Ocean. A. sulcaticauda and L. affinis are redescribed. The male of L. affinis shows remarkable sexual dimorphism in the shape of per eo pods 4 to 6. A new character, the structure of the comb of setae on article 3 of the mandibular palp, is suggested as valuable for distinguishing the genera within the family Antheluridae. It is concluded that most of the North Atlantic anthurideans are shallow water species, mostly restricted to the Caribbean Sea. The species living in the northernmost part of the North Atlantic belong mainly to genera with a wide bathymetrical distribution and to species rich genera in the area. The Greenland-Iceland-Faeroe Ridge may restrict the dispersal of the deep-living species into the Arctic Ocean, while a rapid decline in the temperature may restrict the dispersal of the shallow living species into the Arctic.
