Abstract

The recently described deep-sea pennatulacean genusPorcupinellawas previously known only by the type species,Porcupinella profundafrom the equatorial eastern Atlantic to the eastern North Atlantic Ocean. New data is provided on morphology, distribution, bathymetry, and related taxa. A second species is added here as well – a new species is described from the Tasman Sea in the southwestern Pacific. The new species,Porcupinella tasmanica, is distinguished fromP. profundaby its distinctive hook-shaped growth form, laterally compressed dorsal keel, and differing regions that are occupied by siphonozooids. A key to the species of the deep-sea pennatulacean family Chunellidae is included based on comparative morphology.
