This species is known only from the type locality, the headwaters of the Pastaza River, in Napo Province, eastern Ecuador. The exact altitude of this site is unclear, though it is clearly a montane locality.
Habitat and Ecology
This is presumably a montane forest species. If it is similar to other species in its genus, it is an explosive breeder in ephemeral pools.
This species has not been seen since the original collection in the 1940s, though this is probably related to the lack of survey effort, and its elusive nature.
There is no precise information, owing to uncertainty relating to the exact location of the type locality.
Its taxonomic status should be reviewed, in particular in relation to Ceratophrys cornuta (Cisneros-Heredia pers. comm.).
This species was resurrected from the synonymy of Ceratophrys cornuta by Mercadal (1986).
