Metarminoidea
Metarminoidea is a provisional taxonomic superfamily of colourful sea slugs, aeolid nudibranchs, marine opisthobranch gastropod molluscs in the clade Nudibranchia.
This name is unfortunately not available as a superfamily name, because it is not based on a genus. It is used here because, as of February 2015, no replacement name has yet been proposed.
