Resumo: | Acanthotylotra a new monotypic genus of freshwater sponge is defined. Its sole species A. alvarengai sp. nov. is described based upon microscopic specimens recovered from the Tocantins river, Pará State, Brazil, when the deep rocky substrate was temporarily exposed downstream from the dam at the time it was closed for lake formation. A unique set of megascleres, allied to the paucity of spongin, the renieroid skeleton and the fact that gemmules or new specimens remain undetected, call for the proposition of a new monospecific genus to be retained as incertae sedis until new larger and probably gemmuliferous specimens come to be found.
