This species occurs in north-western Paraguay (Chaco Department), and possibly in southern Brazil. It appears that a Peruvian record is likely to have been a misidentification, as the species has not been recorded from anywhere else in the Amazon basin.

Red List Status
Data Deficient (DD)
Listed as Data Deficient in view of continuing uncertainties as to its taxonomic status, extent of occurrence and ecological requirements.
This species has an uncertain status and is not known from the Amazon basin. It might be a synonym of Rhinella poeppigii. Duellman and Schulte (1992) pointed out that there is no known type specimen for this species, although Frost (2000) listed the distribution as "Peru and Paraguay", and Rodriguez et al. (1993) listed it as occurring in Puno Department, Peru. It is believed that the Peruvian record is a misidentification.
