Plakobranchidae is afamily ofsea slugs,marineopisthobranchgastropodmollusks in the superfamilyPlakobranchoidea.[2] They superficially resemblenudibranchs but they are sacoglossans, members of thecladeSacoglossa within theOpisthobranchia.
Elysiidae was originally described as "Elysiadae" by Forbes & Hanley in 1851 in the bookA history of British Mollusca and their Shells 3:613. In thetaxonomy of Bouchet & Rocroi (2005), the family Elysiidae is considered to be a synonym of the family PlakobranchidaeGray, 1840.
The original spelling Placobranchidae, based onPlacobranchus, an incorrect subsequent spelling byFérussac (1824) in a translation of van Hasselt's work. Franc (1968: 848) and Jensen (1996: 92) attributed the name to Rang, 1829 (p. 134), who used the vernacular "les Placobranches". Jensen (1997: 180-181) argued for the restoration of the spelling Plakobranchidae, and she has been followed by Wägele & Willan (2000: 91). Bouchet & Rocroi (2005: 133), argued that the spellingsPlacobranchus and Placobranchidae were in prevailing usage and were conserved under Art. 33.3.1. This view has been challenged by R. Burn and the spelling Plakobranchidae is now preferred.
