Note
The species of the genus Aporrhais Da Costa, 1778 (Gastropoda, Aporrhaidae) of the italian
Plio-Pleistocene are described and illustrated. To the three species known, A. pespelecani
pespelecani (Linnaeus, 1758), A. uttingeriana (Risso, 1826) and A. peralata (Sacco, 1893),
the new species A. etrusca n. sp., reported only for the Zanclean period of Tuscany (central
Italy) and A. pliorara (Sacco, 1893), distributed from the Piacenzian to the Lower Pleistocene
(Calabrian), elevated to species, are added; moreover, A. pespelecani var. crenatulina
(Sacco, 1893), the most common in the italian lower-middle Pliocene, widespread from the
Tortonian to the Piacenzian, is elevated to subspecies. A. serresiana (Michaud, 1827) is
considered to have occurred in the Mediterranean basin only in very recent times. The examined
species were compared either with extant taxa of Mediterranean (A. pespelecani pespelecani,
A. serresiana) and Afro-Atlantic origin (A. pesgallinae Barnard, 1963 A.
senegalensis Gray, 1838) or with species of the European Neogene: A. burdigalensis (d'Orbigny,
1852), A. meridionalis (Basterot, 1825), A. alata (Von Eichwald, 1830), A. dingdenensis
Marquet, Grigis et Landau, 2002, A. scaldensis Van Regteren Altena, 1954 and A.
thersites Brives, 1897.
