We describe a new species of Bufo from the Andes of southern Ecuador. This species is assigned to the phenetic Bufo spinulosus group based on its narrow frontoparietals, poorly developed cranial crests, and weak sculpturing of the dermal roofing bones. This species most closely resembles B. spinulosus, but they differ from one another in several aspects of their external and cranial morphology. A key is provided for the species of the Bufo from the Andes of Ecuador and Peru.
