No confirmed records from Norway


The records of this species from Norway (Oslofjord) cannot be confirmed since the specimens appear to have been lost (Hjertager, 1998).

Similar species

Melinna palmata is very similar to Melinna cristata. It can be separated from M. cristata by the absence of neurochaetae on the fourth thoracic chaetiger and the scalloped dorsal crest, since M. cristata has neurochaetae on the fourth thoracic chaetiger and has a serrated dorsal crest.
