North Atlantic species of the genus Stegocephaloides SARS (Amphipoda, Stegocephalidae)

Four species (including one new to science) of the stegocephalid genus Stegocephaloides SARS, 1891 are recognized from the North Atlantic Ocean, viz. Stegocephaloides auratus (SARs, 1883), S. barnardi sp. nov., S. christianiensis (BOECK 1871) and S. wagini (GURIANOVA, 1936). Descriptions of all four species are presented together with a discussion of the generic status of some of the other species (S. katalia BARNARD, 1962; S. vegae OLDEVIG, 1959 and S. vanhoeffeni SCHELLENBERG, 1926). The present paper is based primarily on material collected during the BIOFAR and BIOICE projects, and this revision brings the total number of species in the genus up to eight. A key is presented which allows all Stegocephaloides species to be distinguished.
