Euctenidiacea
The Euctenidiacea, common name dorid nudibranchs, are a taxonomic suborder of sea snails or slugs, marine gastropod molluscs in the order Nudibranchia. Bouchet & Rocroi rejected the name Anthobranchia on the grounds that it also included Onchidium at the time of original publication. Doridina is equivalent and used in the latest classification.
A morphological phylogenetic study, published in 2000, by Wägele & Willan showed that the subclade Gnathodoridacea and the subclade Doridacea each form a monophyletic group.
In a later study, published in 2002, A. Valdés concluded that the superfamilies Doridoidea and Phyllidioidea formed a clade. He expanded the usage of Cryptobranchia to encompass the whole subclade Doridacea. This move was not followed in the taxonomy of Bouchet and Rocroi.Taxonomy
