ABSTRACT In the present paper are reported new and little known land snails from Sicily (Mollusca
Gastropoda). Particularly, Platyla similis (Reinhardt, 1880) (Aciculidae) and Rumina sa-
harica Pallary, 1901 (Subulinidae) are first recorded in the island; new taxonomic data,
useful for a better systematic classification, are provided on two little-known taxa, Lam-
pedusa lopadusae nodulosa Monterosato, 1892 (Clausiliidae) and Cernuella (Cernuella)
tineana (Benoit, 1862) (Hygromiidae); and finally, a new species of slug, Tandonia mari-
nellii n. sp. (Milacidae), currently known from North-Western Sicily, is described.
