Four species (including one new to science) of the stegocephalid genus
Stegocephaloides SARS, 1891 are recognized from the North Atlantic Oc
ean, viz. Stegocephaloides auratus (SARs, 1883), S. barnardi sp. nov.,
S. christianiensis (BOECK 1871) and S. wagini (GURIANOVA, 1936). Desc
riptions 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.
