We report some decapod crustaceans from the Pliocene of Castel di Sotto (Novazzano, Canton Ticino, Switzerland). The specimens are assigned to Ctenocheles sp . (Ctenochelidae Manning & Felder, 1991), Retropluma sp. (Retroplumidae gill, 1894), and Goneplax sp. (Goneplacidae MacLeay, 1838). Ctenocheles sp. represents the first report for the genus in the Pliocene of the Mediterranean basin, whereas the presence of Goneplax sp. and Retropluma sp. enlarges the geographic distribution of these genera to the northernmost border of the Padanian Gulf of the Pliocene palaeo-Adriatic Sea. Moreover Goneplax and Retropluma are reported for the first time from the Switzerland fossil record. A single loose right chela has been assigned to an indeterminate ?Cancridae, representing the first report of this family in the Switzerland fossil decapod record.
