This manuscript provides the first detailed taxonomic study and stratigraphic implications of the non-marine ostracods from the post-rift sequence of the Jatobá basin and presents two new species of ostracods found in coeval deposits of the Araripe basin in Northeastern Brazil. The study was carried out on 179 core samples collected from the 2-JSN-01-PE borehole, which was drilled in the locality of Serra Negra, Municipality of Ibimirim, State of Pernambuco (PE), and 165 levels sampled along the boreholes (1-PS-05-CE, 1-PS-06-CE, 1-PS-07-CE, 1-PS-09-CE, 1-PS-11-CE, 1-PS-12-CE and 1-PS-13-CE) drilled on the eastern edge of the Araripe basin in the states of Ceará and Pernambuco in the trough of the Santana Project (Phase II) executed by the Geological Survey of Brazil (CPRM) in the 1970s. A total of 13 ostracod species (Cypridea araripensis, Neuquenocypris berthoui, Damonella ultima, Ilyocypris sp., Rhinocypris cf. R. jurassica, Rhinocypris aff. R. diademae, Pattersoncypris micropapillosa, Pattersoncypris angulata, Pattersoncypris salitrensis, Theriosynoecum silvai, and Alicenula leguminella) and two new species (Damonella grandiensis n. sp. and Candonopsis alagoensis n. sp.) were identified in lacustrine deposits of the Araripe basin. This detailed taxonomic study provides the first dating of the interval corresponding to the Aptian–early Albian to the Jatobá basin, with the addition of a new perspective (including the proposal of two new species) involving the fauna of ostracods found in the Araripe basin.
