Abstract:

Atorella octogonos, a new species of coronate scyphomedusa from the Bahamas, is described based on material collected at approximately 500 m by the submersible Johnson-Sea Link II. This medusa is distinct from other Atorella species in having eight gonads, whereas the other known species have four or six gonads. Consideration of this new material along with recent descriptions of Atorella polyps has lead us to conclude that the hexamerous symmetry of this genus was probably derived from a typically tetramerous nausithoid ancestor. Consequently, it is recommended that the genus Atorella be transferred to the family Nausithoidae, to which it appears to be most closely related.
