Six new species of Macellicephala (Annelida: Polynoidae) from the Southern Ocean and south Atlantic with re-description of type species
Increased sampling efforts in unexplored regions of the Southern Ocean (including depths >500 m) combined with the use of an epibenthic sledge resulted in a large collection of mobile, scale-bearing worms from the family Polynoidae Kinberg, 1856. The greatest taxonomic novelty was found in the ge...

The holotype of type taxon Macellicephala mirabilis McIntosh, 1885 as well as historic material of Macellicephala collected from the Southern Ocean enabled comparison with the modern material.
