Abstract
Recent surveys on freshwater sponges at the very north and south of Brazil yielded specimens of the genus Melania which possessed the peculiar second kind of spiny megascleres described for M. spinata (CARTER, 1881) but did not show the anisochela series of microscleres described by VOLKMER-RIBEIRO (1984) for that species. A renewed comparative study with the syntypic series of M. spinata took to the selection of lectotype and paralectotypes, the redescription of the species and the description of a new species M. kiliani. Only M. kiliani n. sp. has a second class of microcleres made up of anisochelas. A new key is also proposed to sort out the five species of Metania now ascribed to the Neotropical Region.
