Runcinoidea is a taxonomic superfamily (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005) or a clade Runcinaecea (according to the Malaquias et al. (2009)^[2]) of sea slugs, marine gastropod mollusks in the clade Euopisthobranchia.^[1]

Taxonomy

Runcinoidea was recognized as a superfamily in the clade Cephalaspidea, within the informal group Opisthobranchia in the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).^[3]

They also recognized two families, Runcinidae and Ilbiidae.^[3]

Malaquias et al. (2009)^[2] reinstated Runcinacea as a valid taxon outside the Cephalaspidea.

They also recognized two families Runcinidae (with genus Runcina) and Ilbiidae,^[2] but they did not mention superfamilies.

Jörger et al. 2010^[1] moved Runcinacea to the Euopisthobranchia.

Families within the Runcinoidea include:
