Abstract

Ristedtia vestiflua is described as a new genus and species of cheilostomatous Bryozoa from the Arctic Vesterisbanken Seamount, located in the central Greenland Sea. The currently monospecific genus Ristedtia is included in the family Pyrisinellidae. It is characterised by a paired series of opesiules, interzooidal avicularia and hyperstomial, globular ovicells with a triangular endooecial frontal exposure. Its relationship to other members of this family as well as its habitat preference is discussed. It is suggested that the Recent genera of this family represent Tethyan relicts.
