The occurrence of the alien species Anadara transversa is reported for the first time in the Bay of Biscay, from two estuaries of northern Spain (Villaviciosa and Eo), constituting its northernmost distribution in E. Atlantic to date. We present a detailed diagnosis and illustrations of the species in order to facilitate its differentiation from other native ark clams and the introduced A. kagoshimensis. Furthermore, the potential pathways for its introduction in the area are discussed.
