A new Ampharetid (Tolychaeta, Sedentaria) has been collected in the deep sea during the French-Swedish Expedition NORBI in the east-Groenland basin. It represents the type of a new genus, Melythasides gen. nov., characterized by two modified setigerous segments, three pairs of gills, twelve uncinigerous thoracic segments and thoracic uncini with 5-6 series of teeth. The addition of another genera with one or several modified thoracic segments leads to a reconsideration of the taxonomic importance of this character.
