Charcotiidae Dironidae Goniaeolididae Heroidae Proctonotidae Madrellidae Pinufiidae Embletoniidae Metarminoidea is a provisional taxonomic superfamily of colourful sea slugs, aeolid nudibranchs, marine opisthobranch gastropod molluscs in the clade Nudibranchia.

[1] The nudibranchs in this superfamily share with the Aeolidida the possession of dorsal cerata.

In the Goniaeolididae the digestive gland is ramified beneath the skin but does not extend into the cerata.

[2] In the Proctonotidae the cerata are cored with extensions of the digestive gland which terminates midway up the ceras in some species and extends to the tip in others.

[3] The anus may be on the right-hand side of the body (as in aeolids) or in the middle of the back towards the tail end (as in dorids).
