Aeolidioidea

Aeolidioidea is a superfamily of sea slugs, the aeolid nudibranchs. They are marine gastropod molluscs in the suborder Cladobranchia.

Taxonomy
As of 2019, the superfamily Aeolidioidea consisted of the following families:
 * Aeolidiidae Gray, 1827
 * Babakinidae Roller, 1973
 * Facelinidae Bergh, 1889
 * Flabellinopsidae Korshunova, Martynov, Bakken, Evertsen, Fletcher, Mudianta, Saito, Lundin, Schrödl & Picton, 2017
 * Glaucidae Gray, 1827
 * Myrrhinidae Bergh, 1905
 * Notaeolidiidae Eliot, 1910
 * Piseinotecidae Edmunds, 1970
 * Pleurolidiidae Burn, 1966

Synonyms of families within this superfamily include:
 * Caloriidae (accepted as Facelinidae)
 * Cratenidae (accepted as Facelinidae)
 * Favorinidae (accepted as Facelinidae)
 * Phidianidae (accepted as Facelinidae)
 * Phyllodesmiidae (accepted as Myrrhinidae)
 * Protaeolidiellidae (accepted as Pleurolidiidae)
 * Spurillidae (accepted as Aeolidiidae)

Gosliner et al. (2007) elevated the subfamily Babakininae, which was within Facelinidae, to the family level, as Babakinidae. A study of facelinid relationships in 2019 removed several facelinid genera to the family Myrrhinidae.
