Deep-sea reefs and coral banks are increasingly known as highly biodiverse ecosystems where sponges constitute a significant proportion of builders and inhabitants. Albeit smaller in dimensions, Campos Basin coral mounds also harbor a rich associated fauna, whence only 16 species of sponges had been fully identified this far. Seven new species are described here, viz. Geodia garoupa sp. nov., Vulcanella stylifera sp. nov., Trachyteleia australis sp. nov., Echinostylinos brasiliensis sp. nov., Xestospongia kapne sp. nov., Sympagella tabachnicki sp. nov., and Leucopsacusbarracuda sp. nov. Of the 24 species of sponges known from the area, only seven were found elsewhere too, thus suggesting a possible high endemism in Campos Basin. Nevertheless, the widespread occurrence of deep reef-framework building corals along a large sector of the Brazilian coast suggests these habitats and their associated fauna may be more widespread than currently appreciated. Echinostylinos patriciae nom. nov. is proposed for the New Zealand record of E. reticulatus.
