New data on land and freshwater molluscs of Sifnos Island and Kitriani Islet (Cyclades, Greece)

The present report provides an updated checklist of land and freshwater molluscs from Sifnos Island and, for the first time, from the nearby uninhabited islet Kitriani (Greece, Cyclades) with a critical review of available literature. Taxonomy, distribution, biogeographic issues, and the potential effect of human activities on these molluscs’ communities are discussed. New morphological data for some snail species are presented, particularly for the genera Limax Linnaeus, 1758; Xerocrassa Monterosato, 1892; Monacha Fitzinger, 1833; and Albinaria Vest, 1864. Finally, based on shell and genitalia morphology, a new subspecies - Albinaria turrita rosettae n. ssp. - is described.
