MCZR–M–30040— 2 vdx “ Nucula apicina Monts S. Flavia”    Typelocality.Described from S. Flavia† and Altavilla † ( Sicily).   Remarks.Monterosato (1891a: 97) explicitly reported a single specimen (a single valve?) from the Quaternary outcrop of Santa Flavia, near Altavilla Milicia (Palermo). At the end of the description he wrote that the species was also known from Altavilla Milicia. Recorded by MolluscaBase (2018) as taxon inquirendum. However, La Perna (2007), after examination of the Monterosato material and additional material from the outcrop of Monti della Farnesina in Rome (Cerulli-Irelli coll., Palaeontological Museum of Sapienza University of Rome), regarded  Nucula apicinaas a full valid Plio-Pleistocene species, an interpretation that we share. 1915523921 [151,890,1156,1181] S.
