The Chromodorididae (Opisthobranchia: Mollusca) of the Indo-West Pacific: a review of the genera

The full anatomy of over fifty species of the Chromodorididae is described including the type species of all but one of the nominal genera. The holotype material of the type species of Ehrenberg's problematic genera Glossodoris, Actinodoris and Pterodoris is described. Sixteen genera are recognized within the family Chromodorididae including four new monotypic genera. Glossodoris is shown to be a senior synonym of Casella, not Chromodoris, and Ceratosoma and Verconia are shown to be members of the Chromodorididae. The separation of Cadlina, Tyrinna and Cadinella into a separate sub-family Cadlininae is considered unnecessary. A large suite of characters including features of the external shape, mantle glands, gills, foregut, jaw-plates, radula and reproductive system are used to define the genera. A tentative phylogeny of the family is proposed.
