Thank you Vicenç.

Hi Brian and Vicenç,

I would like to confirm the statement of Vicenç by adding the opions of Austrian malacologists. A recent (2013) species list of aquatic neozoa in Austria that also put some emphasis on proper nomenclature uses the name Pseudosuccinea columella . The list can be found in RG (Moog, O., P. Leitner & T. Huber (2013): Aquatische Wirbellose Neozoa in Österreich.- in: Ofenböck, G.- Aquatische Neobiota in Österreich - Stand 2013. Bundesministerium für Land- und Forstwirtschaft, Umwelt und Wasserwirtschaft, Vienna: 54-91.)

Other lists also use Pseudosuccinea columella:  like “Checklists of Austrian Molluscs” (http://ipp.boku.ac.at/private/wf/Check_List_of_Austrian_Mollusca.html),

 “The living world of Molluscs (http://www.molluscs.at/gastropoda/index.html?/gastropoda/freshwater/lymnaea.html), or the „Molluscs of Centrral Europe” http://www.mollbase.org/list/index.php?aktion=zeige_taxon&id=230
