considers Sorbeoconcha an alternate representation of Caenogastropoda and gives the following reasoning:
Sorbeoconcha should include
erithioidea + Campaniloidea + all Hypsogastropoda (i.e. the remaining Caenogastropoda) see definition in Ponder & Lindberg, 1997: 225, not only
erithioidea + Campaniloideaas suggested by the indent pattern in Bouchet & Rocroi.
Neotaenioglossa Haller, 1892 suggested in Ruud Bank’s draft for Fauna Europaea is not retained because it would need severe emendation to remove Pyramidellids, Cerithioids, etc.. included in its original definition, and therefore would be too far from Haller's concept if it were to fit the concept of Sorbeoconcha.
Although cladistically sound, the taxon Sorbeoconcha is skipped in the classification scheme because (1) ten years after its publication, the name still sounds unfamiliar to most and (2) it is not very helpful in the classification because it includes the bulk of Caenogastropoda (only keeping out small stem groups Abyssochrysidae, Provannidae, and the architaenioglossate taxa). This is not final, opinions are welcome.
