<i>Sphaerodoropsis amoureuxi</i> and <i>S. stellifer</i>, two new species of Sphaerodoridae (Polychaeta) from the Capbreton Canyon (Bay of Biscay, NE Atlantic).
Seven specimens belonging to three species of sphaerodorid polychaetes were collected from bathyal depths (492-1113 m) of the Capbreton Canyon, Bay of Biscay, NE Atlantic. Two of them, Sphaerodoropsis amoureuxi and S. stellifer, collected at a depth of around 1000 m, are new to science. S. amoureuxi is characterized by having three pairs of lateral prostomial appendages and a single transverse row of eight dorsal macrotubercles per segment. S. stellifer has three pairs of lateral prostomial appendages, a single transverse row of four dorsal macrotubercles per segment, and papillae ending in a star shape. The third species, Sphaerodoridium fauchaldi, was collected at a depth of around 500 m; it is the first record since its description. In order to be in accord with the findings of Orrhage, an amendment of the nomenclature of the head appendages of sphaerodorids with three pairs of "antennae" is proposed.
