The research was carried out from 2010 to 2013 inside a Site of Community Importance (SCI) and a Special Protection Area (SPA), of the Cilento, Vallo di Diano and Alburni National Park. The non-marine molluscs sampled on the field were compared with data available from the literature and malacological collections. Up to now, only 12 non-marine Mollusc species were known from the Alburni Mountains through bibliographical data. In all, the malacofauna of Alburni Mountains is composed by 83 non-marine Mollusc species (73 species of land snails, and 10 species of freshwater molluscs). The presence of nine species (six species of land snails and three species of freshwater snails) was confirmed by our field investigation, four species (3 species of land snails and 1 species of allochthonous freshwater snails) were recorded only by bibliographical data and were not yet found. Our analysis identifies 70 species of non-marine Molluscs (64 species of land snails, 6 species of freshwater molluscs) recorded on the basis of field data which were not previously recorded from the study area. At least 11 species are new records for the Campania Region. Extremely interesting is the record of Vertigo angustior Jeffreys, 1830 a species protected in European Union by the Annex II of the “Habitats Directive” and listed as “Vulnerable” at the European level. A Red List of Threatened Species is proposed and the species were classified with the code of I.U.C.N. (Version 2014.3). Five allochthonous species were surveyed for the first time in the study area: 3 land snails: Lucilla scintilla (Lowe, 1852), Lucilla singleyana (Pilsbry, 1829) and Paralaoma servilis (Shuttleworth, 1852), and 2 freshwater snails: Potamopyrgus anti- podarum (J.E. Gray, 1843) and Ferrissia fragilis (Tryon, 1863). Four species are known exclusively from the literature: Vertigo (Vertigo) moulinsiana (Dupuy, 1849), Macrogastra (Pyrostoma) plicatula (Draparnaud, 1801), Cernuella virgata (Da Costa, 1778), and Haitia acuta (Draparnaud, 1805).
