title: On a new genus and species of Hemicytheridae (Ostracoda, Crustacea) from the southern Brazilian coast

description: This dataset contains the digitized treatments in Plazi based on the original journal article de Morais, Anderson L. M., Coimbra, João C. (2014): On a new genus and species of Hemicytheridae (Ostracoda, Crustacea) from the southern Brazilian coast. Iheringia, Série Zoologia (Série Zoologia) 104 (3): 367-372, DOI: 10.1590/1678-476620141043367372, URL: http://dx.doi.org/10.5281/zenodo.7802489ABSTRACT. This study is based on 62 samples of phytal and bottom sediments collected along rocky beaches (≤ 3 m water depth) of the central and northern coasts of the state of Santa Catarina (26°10’/27°50’S – 48°26’/48°40’W), southern Brazil. Living and dead ostracodes distributed among 16 families were recovered. In this paper is emphasized one new hemicytherid genus and species that is described and richly illustrated: Auricythere sublitoralis gen. nov. and sp. nov. Some ecological and zoogeographical aspects of this new ostracode are briefly discussed.KEYWORDS. Taxonomy, Aurilini, state of Santa Catarina, Atlantic Ocean.RESUMO. Sobre um novo gênero e espécie de Hemicytheridae (Ostracoda, Crustacea) da costa sul-brasileira. Foram coletadas 62 amostras de sedimentos de fundo e fital no infralitoral rochoso superior (≤ 3 m de profundidade) das regiões central e norte do Estado de Santa Catarina (26°10’/27°50’S – 48°26’/48°40’W). Os ostracodes vivos e mortos recuperados estão distribuídos em 16 famílias, destacando-se, neste trabalho, um novo gênero e espécie de Hemicytheridae ricamente descrito e ilustrado: Auricythere sublitoralis gen. nov., sp. nov. Alguns aspectos ecológicos e zoogeográficos deste novo táxon são brevemente discutidos.PALAVRAS-CHAVE. Taxonomia, Aurilini, Estado de Santa Catarina, Oceano Atlântico.The study of benthic marine ostracodes from Brazil began with BRADY (1880), in his monumental work on benthic ostracodes from different oceans, identified some species of ostracodes recovered, including from deep-waters of northeastern region of Brazil, all of them collected during the H.M.S. Challenger Expedition. HARTMANN (1955, 1956) described some new species from samples collected by hand off Santos city and Bela Island, both places localized in the north coast of the state of São Paulo, southeastern Brazil. Later, PINTO et al. (1978), a landmark in the study of these microcrustaceans in this country examined hundreds of bottom sediment samples collected along 7,408 km of the continental shelf, identifying, preliminarily, about 50 genera of Ostracoda. Following them, RAMOS (1996), COIMBRA et al. (1999), MACHADO et al. (2005) and BERGUE & COIMBRA (2008) continued these studies where a more detailed bibliographic review is presented.Most work on marine benthic ostracodes of Brazil has been devoted to the study of species recovered from the continental shelf, and more recently from the slope (BERGUE & COIMBRA, 2008). Ostracodes from coastal regions are still poorly understood, highlighting herein the studies of HARTMANN (1955, 1956), already cited above, and ORNELLAS (1974, Tramandaí town, state of Rio Grande do Sul), COIMBRA et al. (1992, Tamandaré Bay, state of Pernambuco), DIAS- BRITO et al. (1988, Sepetiba Bay, state of Rio de Janeiro), COIMBRA & BERGUE (2003, São Sebastião town, state of São Paulo), COIMBRA et al. (2007, Cananéia town, state of São Paulo, and references therein) and COIMBRA & BERGUE (2011, northern coast of the state of São Paulo).The main purpose of this study is the description of one new hemicytherid genus and species, Auricythere sublitoralis gen. nov., sp. nov., recovered living and dead from the upper rocky sublitoral (≤ 3 m water depth) of the central and northern coasts of the state of Santa Catarina (26°10’/27°50’S – 48°26’/48°40’W). The other species of ostracodes recorded in the study area, distributed in 16 families, are part of an ongoing project.
