Thirty-one species are recorded for the region, three (Barbatia (Calloarca) tetraquetra. B. (Destacar) colpodes and B. (Acar) petasion) being descriptionbed as new. Arca ventricosa Lamarck, 1819, Barbatia setigera (Reeve, 1844), B. cibotina (MelviU, 1906), Arcopsis ornata (Viader, 1951), Samacar strabo (Hedley, 1915) and Anadara dautzenbergi (Lamy, 1907) are recorded for the first time. Arca lienardi Viader, 1951 and Striarca soyoae Habe, 1958 are synonyms of Barbatia cibotina; Arcopsis minabensis Habe, 1981, and Ribriarca okinawaensis Noda, 1980 are synonyms of Arcopsis ornata; Area lactea var. gibba Krauss, 1848 is a synonym of Arcopsis symmetrica (Reeve, 1844). Barbatia setigera, B. agulha­sensis, (Thiele, 1925) and Anadara africana (Sowerby, 1904) are reinstated as valid species. Deltaodon Barnard, 1962 is treated as a subgenus of Samacar Iredale, 1936 and Ribriarca Noda, 1980 as a synonym of Arcopsis von Koenen, 1885. The subfamily Anadarinae is regarded as a syno­nym of the Arcinae. Barbatia tetraquetra proves to be incubatory.
