Doridina
Introduction The '''Doridina''', common name '''dorid nudibranchs''', are a taxonomic suborder of sea snails or slugs, marine gastropod molluscs in the order Nudibranchia. Bouchet & Rocroi (2005) 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 (= Bathydoridoidea) and the subclade Doridacea (= Phanerobranchia + Cryptobranchia + Porostomata) each form a monophyletic group.In a later study, published in 2002, A. Valdés concluded that the superfamilies Doridoidea and Phyllidioidea (called by him Cryptobranchia + Porostomata) 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.
