A new commensal species of polychaete has been discovered living between the gills of the deep-sea thyasirid clam, Thyasira insignis. The collections come from dense faunal communities recently discovered on the Laurentian Fan off Newfoundland and Nova Scotia. The species is named Petrecca thyasira new genus, new species, and is referred to the recently described family Nautilinidae, that was previously known for a single species associated with clams from the Japan Trench. Only one pair of antennae and a single tentacular segment are present. The subbiramous parapodia are well developed, but setae are reduced to one or two large hooked neuropodial spines. Nomenclatural problems that call into question the validity of the genus name Nautilina and the family name Nautilinidae are discussed.
