Classification Established as an order containing the superfamilies Architaenioglossa, Valvatacea, Rissoacea, Littorinacea, Cerithiacea, Ptenoglossa, Aglossa, Amaltheacea, Naticacea, Lamellariacea, Cypraeacea, Calyptraeacea, Heteropoda, Strombacea, and Doliacea. Spelling emended by Anderson (1992: 36) to Mesogastropodida.
Thiele (1925) included the three orders Archeogastropoda, Mesogastropoda, Neogastropoda in his concept of the subclass Prosobranchia, in a classification which has been a standard throughout the remainder of the XXth century and is still presented in current zoology textbooks (e.g. Brusca & Brusca, 2003). Currently the Archeogastropoda and Mesogastropoda are rebutted as paraphyletic, whereas Neogastropoda is considered a monophyletic group ans therefore still accepted (as an order of the Caenogastropoda).
Families formerly included in the Mesogastropoda are currently included in the broader (monophyletic) taxon Caenogastropoda, either in the poorly supported, possible clade Littorinimorpha, or as Caenogastropoda of unresolved position (not assigned to an order). [details]
