Abstract

We describe a new species in the Scinax granulatus group from the Atlantic Forest of northeastern Brazil and include the new species in an updated phylogenetic hypothesis for the group. The new species differs from all other species in the S. granulatus group by a combination of characters, such as a weakly bilobate vocal sac, moderately developed pre- and postaxial webbing of Toe IV, and advertisement call features. The newly described taxon is more similar with S. tropicalia, a species that is not closely related; both can be distinguished by the red-colored iris in the new species and differences in pulse rate of the call. The new species was recovered as the sister taxon of a clade including all other species of the S. granulatus group. However, the low support of some internal clades suggests that the knowledge about relationships in this group is still incomplete. (AU)
