Abstract

Three species of Desmacella Schmidt, 1870 are described from the Brazilian coast: Desmacella microsigmata sp. nov., Desmacella tylovariabilis sp. nov. and Desmacella annexa Schmidt, 1870. The new species were compared with Desmacella species from the Atlantic Ocean, which differ by the size of their spicules and by the presence of microspined sigmas. Desmacella annexa was found to have microspined toxiform microxeas and sigmas. Desmacella now contains 31 species distributed worldwide.
