The nine oceanic islands that comprise the Azores archipelago are located in the middle of the northern Atlantic Ocean. In this isolated archipelago, there is a rich fossil record in one of the islands, Santa Maria. In this island, samples were collected in the Upper Miocene composite section of Malbusca outcrop, located in the southern shore of the island, and the fossil marine Ostracoda were studied. This work represents the first report of fossil ostracods from the Azores archipelago. Thirteen species were found, representing seven families and 12 genera (Xestoleberis, Loxoconcha, Callistocythere, Leptocythere, Dameriacella, Aurila, Heliocythere, Pachycaudites, Neonesidea, Cyamocytheridea, ?Quadracythere and Paracypris). Among the identified species, one new species, Leptocythere azorica n. sp., is described. Loxoconcha (two species) was the most diversified genus. The collected species are mainly ornamented and typical of warm waters and epi-neritic habitats (∼10–50 m of depth). © 2012 Elsevier Masson SAS. All rights reserved.
