On Metania spinata (CARTER, 1881) and Metania kiliani n. sp.: Porifera, Metaniidae VOLKMER-RIBEIRO, 1986

Abstract

Recent surveys on freshwater sponges at the very north and south of Brazil yielded specimens of the genus Merania which possessed the peculiar second kind of spiny megascleres described for M. spimta (CARTER. 1881) but did not show the anisochela series of microscleres described by VOLKMER-RIBEIRO (1984) for that species.
