The present paper reports the occurrence of the Antarctic coralFlabellum impensumin Tierra del Fuego Province, Argentina, and extends its distribution northwards in the south-west Atlantic Ocean. Nine individuals were found in Argentinean coastal waters in 2014, also representing one of the shallowest records of the species.

Present Distribution

The present study deals with six new records of octocoral species (two alcyoniid soft corals and four primnoid gorgonians) for the south western Atlantic Ocean. These new records, mainly for the gorgonians, improves the knowledge of their present distribution. The species Thouarella koellikeri and Dasystenella acanthina have their known distribution widened, showing in the first case a continuous bioceanic distribution (south east Pacific south west Atlantic). The species of the genus Primnoella, P. biserialis and P. compressa, widen their distributional range tending to a geographical continuity along the south eastern coasts of the American continent, avoiding the zoogeographic barrier constituted by the R o de la Plata.

Sigmaxinella cearense sp. nov. is described here on the basis of a single specimen collected in 2004 at Parque Estadual Marinho da Pedra da Risca do Meio, off Fortaleza, Ceará, Brazil. This is the first record of Sigmaxinella for the Atlantic Ocean. The new species differs from the other eleven Sigmaxinella species by the absence of raphides/microxea, and is the only species with a single category of styles as megascleres (mean length 435µm, mean width 12µm), and sigmas (mean length 21µm). The new species appears to be closer to Australian species of Sigmaxinella, on the basis of overall spicule morphology (mainly dimensions and categories of megascleres). This could be suggestive of a transpacific track for the colonization of the South Atlantic, instead of the shorter Agulhas track.Key words: Sigmaxinella, taxonomy, Parque Estadual da Pedra da Risca do Meio, sponge, new species, sandstone reef, Brazil
