description: This dataset contains the digitized treatments in Plazi based on the original journal article Nathália C. da Luz, João C. Coimbra (2014): New species of Xestoleberididae (Crustacea, Ostracoda) from Archipelago of São Pedro and São Paulo, Equatorial Atlantic. Iheringia, Série Zoologia 104 (4): 470-477, DOI: 10.1590/1678-476620141044470477, URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0073-47212014000400013&lng=en&tlng=enABSTRACT. Two new species of Xestoleberididae: Xestoleberis brasilinsularis sp. nov. and Xestoleberis machadoae sp. nov., both endemic to Archipelago of São Pedro and São Paulo, are described.The record of these shallow marine waters species from Brazilian oceanic islands represents an important contribution to the knowledge of the evolutionary history the species inhabit areas.KEYWORDS. Xestoleberis, taxonomy, morphology, Atlantic Ocean.RESUMO. Novas espécies de Xestoleberididae (Crustacea, Ostracoda) do Arquipélado de São Pedro e São Paulo, Atlântico Equatorial. Duas novas espécies de Xestoleberididae: Xestoleberis brasilinsularis sp. nov. e Xestoleberis machadoae sp. nov., ambas endêmicas do Arquipélago São Pedro e São Paulo, são descritas. O registro dessas espécies marinhas de águas rasas em ilhas oceânicas brasileiras representa uma importante contribuição para o conhecimento da história evolutiva das espécies que habitam estas áreas.PALAVRAS-CHAVE. Xestoleberis, taxonomia, morfologia, Oceano Atlântico.The oceanic islands are of great scientific interest, mainly their origins and their very special terrestrial and marine ecosystems. The island environments have been used as a model for many scientific fields, such as biogeography, ecology, evolution and conservation. In recent decades, the study of the Brazilian oceanic islands and their flora and fauna has grown significantly with the financial support of the governmental program known as PROARQUIPÉLAGO. This program is also responsible by the logistical support to the researches performed in the Archipelago of São Pedro and São Paulo, that is a group of very small rocky islets in the Equatorial Atlantic Ocean (CAMPOS et al., 2003; COIMBRA et al., 2009, 2013; ANTONIETTO et al., 2012; COIMBRA & CARREÑO, 2012).COIMBRA et al. (2013) is an important contribution to the knowledge of the ostracod fauna from the Archipelago of São Pedro and São Paulo. The authors identified and illustrated 14 species, described one new genus and species and leaving the two species of the genus Xestoleberis Sars, 1866, herein described, in open nomenclature.Xestoleberis, a cosmopolitan marine ostracod genus, is the most specious Xestoleberididae and possesses a rich fossil record, being known since the Cretaceous (MORKHOVEN, 1962). This genus prefers shallow marine waters, but some of its species have been recovered from deep sea (DANIELOPOL et al., 1996) and marine marginal environments (DIAS- BRITO et al., 1988). The present paper describes and illustrates two new species of Xestoleberis, both recovered from the cove of the Archipelago of São Pedro and São Paulo, and very likely endemic to this oceanic area.
