Abstract
The monotypic genus Macrogenioglottus Carvalho include the species M. alipioi, described from Ilheus, state of Bahia, Brazil (Carvalho, 1946). Its distribution comprises the Atlantic Forest domain (Ab'Saber, 1967) in the northeastern and southeasternBrazil (Tiburcio et al, 2008). Abravaya and Jackson (1978) described briefly the tadpole of this species. Therefore, a more detailed description of the larval morphology is needed. Tadpoles were collected in temporary ponds of clear water, as well as muddy water, with average depth of 15 cm, located inside the Mata do Catole, Maceio, state of Alagoas, Brazil (9°35'S, 35°49'W; 140 m a.s.L), in July 2006 and September 2010 (collection permits by IBAMA/RAN #184/05 and 24791-1). Two specimens were kept alive through metamorphosis and compared with adult characteristics for species identification. Macrogenioglottus alipioi is the only known species of the family occurring in the area.
