A new Fabriciinae fanworm genus and species, Raficiba barryi, from continental slope depth (318-335 m) off Antarctica is described. The species is the first in the subfamily to be described from this region, as well as the first species known to occur at a depth beyond the continental shelf. Raficiba is most similar to Fabricia Blainville, Parafabricia Fitzhugh, and Brifacia Fitzhugh in having well-developed branchial crown dorsal lips distinct from the dorsal radioles, absence of ventral filamentous appendages, and an anterior peristomial ring collar developed as a ventral lobe. Features distinguishing Raficiba from these genera include shapes of the branchial lobes and collar, the distribution of inferior thoracic pseudospatulate notosetae, and dentition in thoracic neuropodial uncini. A revised key to Fabriciinae genera is provided.
