We describe a new species of the Scinax catharinae group from the highlands of the State of Santa Catarina, southern Brazil. Thenew species is distinguished from the other species of the group for having a trapezoid interocular blotch, an externally distended vocal sac,hypertrophied forearms in males, and the extension of foot webbing on Toe V. This new species brings to 35 the number of species in theS. catharinae group, which stands as the most diversified endemic clade of Atlantic forest frogs. The discovery of a new, distinctive species inthe southern section of the Atlantic Forest, where so far only five species of this clade were known to occur, indicates that we are far from agood understanding of the taxonomic diversity of this species group.
