A new genus and species of a common deep-water narcomedusa is described from the Arctic Ocean. The species has four primary tentacles, four secondary tentacles, with three interradial manubrial pouches in each quadrant. A revision and taxonomic key of the family Aeginidae is presented to account for...

Description
Summary:A new genus and species of a common deep-water narcomedusa is described from the Arctic Ocean. The species has four primary tentacles, four secondary tentacles, with three interradial manubrial pouches in each quadrant. A revision and taxonomic key of the family Aeginidae is presented to account for the new genus. Detailed information on its fine-scale vertical and horizontal distributions show that it occurs in a fairly narrow depth range between 1400–2000 meters. The species was observed 423 times at eleven stations, demonstrating that new species can be common in the under-explored regions of the ocean.
