The Oligocene species ascribed to the Calappidae H. Milne-Edwards, 1837, housed in the palaeontological collections of the Museum “G. Maini” of Ovada (Alessandria, Piemonte, NW Italy) from the Ligure Piemontese Basin, are herein revised in order to verify their systematic assignment. Two additional specimens are ascribed to Calappilia guttata n. sp., whereas one specimen previously ascribed to M. pustulosus is herein assigned to Calappilia sp. The revision allows us to provide an emended diagnosis and new description of Mursiopsis pustulosus Ristori, 1889. Finally the assignment of Stenodromia mainii (Allasinaz, 1987) and Calappilia vicetina Fabiani, 1910is briefly discussed.

Keywords: Crustacea, Decapoda, Brachyura, Calappidae, Oligocene, Italy.
