The volcanic island of Trindade is located 620 miles from the coast of Espirito Santo State, Brazil. This island together with the Martin Vaz Archipelago, are the only visible portions of the Vitoria-Trindade submarine ridge. The benthic flora of this region is poorly known. Of the 17 Chlorophyta, 11 Phaeophyta and 35 Rhodophyta identified (total of 63 taxa), the majority are newly cited for the region (15 Chlorophyta, 10 Phaeophyta, 34 Rhodophyta). The most common orders are Caulerpales (Chlorophyta), Dictyotales (Phaeophyta) and Ceramiales (Rhodophyta).

“…Nevertheless, some studies have been undertaken in order to compile an inventory of the Trindade's biodiversity, for which mechanisms of conservation, protection, and management can be established. They have focused on both the flora (Joly, 1950;Pedrini, 1989;Nassar, 1994;Alves & Guimarães 1998;Yoneshigue-Valentin et al, 2005;Villaça et al, 2006) and fauna (Vannucci, 1950;Carvalho, 1950;Pinto, 1957;Lanzieri, 1966;Brito, 1971;Coelho, 1974;Breure & Coelho 1976;Tavares, 1999;Moraes et al, 2006;Pinheiro et al, 2009;Pereira-Filho et al, 2011). Concerning the study of microfossils, with the exception of a brief report on foraminifers (Rodrigues, 1971) and a book chapter with preliminary data on ostracodes (Coimbra et al, 2009), microfossils groups have not been studied at Trindade.…”

-Twenty-one ostracode species from Trindade Island and 23 species from Rocas Atoll are herein recorded. The collective fauna shows low richness and low abundance compared with other oceanic islands. Nevertheless, the presence of tropical pandemic species such as Kotarocythere inconspicua (Brady) and Triebelina sertata Triebel, of the almost exclusively Pacific genus Australimoosella, the Atlanto-Caribbean taxa such as Glyptobairdia coronata (Brady) and Caudites obliquecostatus Bold, together with species typical of the Brazilian shelf, reveals a mixed fauna likely influenced by dispersal of shallow-water taxa between seamounts during Quaternary sea-level lowstands. In contrast to other oceanic islands, endemic ostracode taxa are apparently absent in these two islands. Tenedocythere trindadensis sp. nov., a species also recorded on the Brazilian equatorial shelf, is described and illustrated.Key words: oceanic island, ostracodes, Rocas Atoll, Trindade Island, zoogeography, paleozoogeography.RESUMO -Foram registradas 21 espécies de ostracodes para a Ilha da Trindade e 23 para o Atol das Rocas. Ambas ostracofaunas mostram baixa riqueza e abundância de espécies quando comparadas com outras ilhas oceânicas. Contudo, a presença de espécies tropicais pandêmicas, como Kotarocythere inconspicua (Brady) e Triebelina sertata Triebel, do gênero Australimoosella que é quase exclusivo do Pacífico, e de táxons atlântico-caribenhos como Glyptobairdia coronata (Brady) e Caudites obliquecostatus Bold, juntamente com espécies típicas da plataforma brasileira, revela uma fauna mista provavelmente influenciada pela dispersão de táxons de águas rasas entre montes submarinos durante períodos de mar baixo ao longo do Quaternário. Contrastando com outras ilhas oceânicas, estas duas ilhas parecem não apresentar espécies endêmicas de ostracodes. Tenedocythere trindadensis sp. nov., uma espécie também registrada na plataforma equatorial do Brasil, é aqui descrita e ilustrada.Palavras-chave: ilhas oceânicas, ostracodes, Atol das Rocas, Ilha da Trindade, zoogeografia, paleozoogeografia.
