REVISION OF THE GENERA OF THE FAMILY TRAP EZIIDAE (MOLLUSCA, BIVALVIA) OF THE CAENOZOIC

The taxonomic position of the Caenozoic genera of the family Trapeziid ae (Trapezium, Coralliophaga, Oryctomya, Neotrapezium, Glossocardia, S traelenotrapezium, Kitsonia) is reviewed. The genus Cabralista, anteri orly Euloxidae is included in the Trapeziidae. The genus Glossocardia does not belong to Trapeziidae and is placed in the Glossidae, and Kit sonia is retransfered in the Kitsoniidae, incertae sedis. Temporarily we keep Straelenotrapezium within the Trapeziidae. The first fossil sp ecies of the genus, Trapezium (s.s.) vivesi nov. sp., is described fro m the Lower Miocene of the Southwest of France.
