Raja mauritaniensis: a replacement name for Raja africana Capapé, 1977 (Rajiformes: Rajidae), a junior homonym of Raja africana Bloch amp; Schneider, 1801 (Myliobatiformes: Dasyatidae).

Raja africana Capapé, 1977 is a primary junior synonym of Raja africana Bloch Schneider, 1801 and therefore permanently invalid (International Code of Zoological Nomenclature, article 57.2) and must be replaced. Raja africana Bloch Schneider, 1801 was first described by Bloch Schneider (1801: 367), based on a specimen from Guinea, West Africa (eastern Atlantic Ocean). The unique holotype is extant in the Zoologisches Museum of the Humboldt University, Berlin (ZMB 7837, a partial dry skin). The species was treated as valid as Urogymnus africanus (Bloch Schneider 1801) by Compagno Roberts (1984: 285), but later synonymized with Urogymnus asperrimus (Bloch Schneider 1801) in the subfamily Urogymninae of the family Dasyatidae (Myliobatiformes) by Compagno (1986: 141), Capapé Desoutter (1990: 63) and Séret (2016: 1418). It is widespread in the eastern Atlantic, Red Sea and IndoWest Pacific.
