Classification The classification of the Gastropoda in three subclasses Prosobranchia, Opisthobranchia and Pulmonata had been set as a standard by Thiele (1929-1931) throughout the XXth century and is still presented in major textbooks (e.g. Brusca & Brusca, 2003).
Nowadays the classification of Gastropoda undergoes considerable reorganization in the attempt to bring it as close as possible to a changing phylogenetic hypothesis of the class. There is compelling evidence that Prosobranchia as classically understood is a paraphyletic taxon, and as a consequence it is being progressively abandoned. Even if one would adopt the standards of Evolutionary Systematics and tolerate paraphyletic taxa under some conditions, it would be embarrassing to maintain Prosobranchia at the same taxonomic rank as Opisthobranchia and Pulmonata, which together form a clade (Heterobranchia) which is at large the sister-group of Caenogastropoda (i.e. part of Prosobranchia).
Following essentially Bouchet & Rocroi (2005, and references therein), the former Prosobranchia are here distributed in separate subclasses (Patellogastropoda, Vetigastropoda, Cocculiniformia, Neritimorpha, and Caenogastropoda) which are all supposed to be monophyletic. [details]
