The Sergipe-Alagoas Basin has one of the most complete, exposed lithological successions of the Cretaceous period in the continental margin of Brazil. It captures several phases of the evolution of the South Atlantic Ocean, including rift, gulf and drift. The upper Aptian–Albian Riachuelo Formation corresponds to the first stages of the southern proto-Atlantic Ocean invasion in that basin. The present study reviews the taxonomic identification and ecology of 39 ostracod species of this formation, proposing a new genus – Gabonorygma gen. nov. – and three new species – Praebythoceratina deltalata sp. nov., Gabonorygma sergipana gen. et sp. nov. and Brachycythere smithsoniana sp. nov. Other taxa include Conchoecia? sp. 1, Cytherella sp. 1, C. besrineensis comb. nov., Cytherelloidea aff. globosa, C. btaterensis, Bairdoppilata sp. 1, Bairdoppilata sp. 2, B. comanchensis comb. nov., B. pseudoseptentrionalis, Robsoniella falklandensis, Cetacella sp. 1, Paracypris eniotmetos, Harbinia sinuata?, H. crepata, Liasina sp. 1, Praebythoceratina amsittenensis comb. nov., P. trinodosa comb. nov., Patellacythere sp. 1, P. shimonensis comb. nov., Xestoleberis? sp. 1, Xestoleberis? sp. 2, Apatocythere? sp. 1, Neocythere? aff. pseudovanveeni, N. (Physocythere) tenuis, Aracajuia antiqua comb. nov., A. benderi, A. fragilis comb. nov., Eocytheropteron sp. 1, Metacytheropteron aff. minuta, Microceratina? sp. 1, M. azazoulensis, Veenia guianensis, Algeriana? sp. 1, Quasihermanites? sp. 1 and Sergipella viviersae.

-A biostratigraphic and paleozoogeographic revision of the upper Aptian-Albian ostracods of Riachuelo Formation, in the Sergipe-Alagoas Basin, Brazil, was conducted. The studied material comprised 336 samples from several outcrops, along with well cores drilled by Petróleo Brasileiro S.A. (PETROBRAS). After taxonomic analysis, including the description of Reticulocosta edrianae n. sp., a new biozonation scheme was obtained for the Albian interval of that formation, and the paleozoogeographic affi nities of the Brazil-Central West Africa province were reviewed through comparison with results published in the current literature. Several changes were made to previously established ostracod zones. A new code for the Aracajuia benderi Zone (OSE-1), MSA-0, was created, with impact in all of its subzones. The names of the Pattersoncypris ex. gr. angulata (OSE-1.1), 'Patellacythere' sp. GA E 27 (OSE-1.3) and Veenia guianensis (OSE-1.4) subzones were changed to Harbinia sinuata? (MSA-0.1), Praebythoceratina amsittenensis (MSA-0.3) and Reticulocosta edrianae (MSA-0.4), respectively. The Sergipella viviersae Subzone (OSE-1.2) had its code changed for MSA-0.2; also, a stratotype was stablished for it, and the lower limit of the subzone was changed, from lower Albian in previous works to upper Aptian. The Metacytheropteon aff. Metacytheropteron sp. GA C 24 Subzone (OSE-1.5) was renamed MSA-0.5. The uppermost Albian Aracajuia antiqua Latest Occurrence Interval Zone (MSA-1) is herein proposed, following the reclassifi cation Aracajuia benderi specimens of the Aracajuia benderi Subzone (OSE-1.6) to Aracajuia antiqua. Paleozoogeographic analyses showed some faunal interchange with Tethyan provinces, beginning in the latest Aptian, at both specifi c and generic levels. Limited northward marine infl uxes across the Walvis ridge were also observed during the Albian, while larger scale southward migrations occurred in the early Cenomanian. The presence of Brachycytherinae species in the Brazil-Central West Africa province as early as the Aptian indicates a new zoogeographic origin for this subfamily, while explaining the occurrence of the group in both the Austral realm and part of the Tethyan realm during the Albian.Key words: Early Cretaceous, South Proto-Atlantic ocean, marine ostracods, MSA-1 Zone, province interchange.RESUMO -Uma revisão bioestratigráfi ca e paleozoogeográfi ca dos ostracodes do Aptiano superior-Albiano da Formação Riachuelo, bacia de Sergipe-Alagoas, Brasil, foi proposta no presente trabalho.
