Paludinella newcombiana Hemphill, 1877: synonym of Littorina subrotundata (Carpenter, 1864)
Notes: Kadolsky (2012) has shown that the real Helix littorina delle Chiaje, 1828, was most probably based on small specimens of Melarhaphe neritoides (Linnaeus, 1758). However, Pfeiffer (1841) based the genus Paludinella on the taxonomic extension given to that name by Philippi (1836), i.e. a misidentified type species. For Paludinella littorina of authors, non delle Chiaje, Kadolsky restored the name Paludinella globularis and, under Art. 70.3 of the code of the International Commission on Zoological Nomenclature, designated the latter as type species of Paludinella.
