Taxonomy

Elysiidae was originally described as "Elysiadae" by Forbes & Hanley in 1851 in the book A history of British Mollusca and their Shells 3:613. In the taxonomy of Bouchet & Rocroi, the family Elysiidae is considered to be a synonym of the family Plakobranchidae Gray, 1840.
The original spelling Placobranchidae, based on Placobranchus, an incorrect subsequent spelling by Férussac in a translation of van Hasselt's work. Franc and Jensen attributed the name to Rang, 1829, who used the vernacular "les Placobranches". Jensen argued for the restoration of the spelling Plakobranchidae, and she has been followed by Wägele & Willan. Bouchet & Rocroi, argued that the spellings Placobranchus 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.
This family has no subfamilies.
