Dysponetus joeli sp. nov. (Polychaeta: Chrysopetalidae) from the north-east Atlantic, with a cladistic analysis of the genus and a key to species
International audience We describe Dysponetus joeli sp. nov. from shallow maerl habitats in the north-east Atlantic (English Channel and Bay of Biscay). Dysponetus joeli differs from congeneric species by a unique combination of characters, including a large syllid-like pharynx, 2–4 simple serrated...
