A new species and genus of microhylid frog are described from Amazonian Peru. The new genus is diagnosed by an incomplete maxillary arcade, which is an apomorphy of the genus. Furthermore, the new species possesses a remarkably large, Type-2 suspension feeding tadpole with unique, large, scalloped flaps pendant over the mouth. Phylogenetic analysis of New World microhylid genera supports a hypothesis in which the new genus is derived relative to Ctenophryne, Otophryne, and Nelsonophryne and is the sister taxon to the remaining genera.
