Remarks.

Corbula erythraeensis   is widespread in the northern Red Sea where it has been recorded from the gulfs of Suez ( MacAndrew 1870; Oliver 1992) and Aqaba at Eilat ( Edelman-Furstenberg and Faershtein 2010), as well as the northern Bay of Safaga (Egypt) ( Zuschin and Oliver 2003); outside the Red Sea, its distribution ranges eastward to Pakistan ( Huber 2010). Here we report the first findings of this species from the Mediterranean. Corbula erythraeensis   was found sympatrically with the common native Mediterranean Corbula gibba   but was always present in very low numbers. No empty shells have been found so far. While being similar in appearance to the morphologically variable C. gibba   , C. erythraeensis   has a convex anterior dorsal margin of the right valve (usually concave in C. gibba   , particularly in smaller specimens), a more inflated umbonal region, a regular concentric sculpture on the left valve ( Oliver 1992), and its color always is whitish-yellowish ( C. gibba   frequently has a rosy pattern). Juvenile individuals are more wedge-shaped than those of C. gibba   .
