This species is found at altitudes of less than 1,000 m in the southern Atlantic Forest of Brazil; through eastern Santa Catarina and Paraná States, to northern Rio Grande do Sul State.
Habitat and Ecology
This species is restricted to lowland Atlantic Forest. It presumably reproduces by larval development in backwaters of streams and in temporary pools. The species is believed to be fairly tolerant of habitat modification.
No information is currently available.
The Atlantic Forest has been subject to substantial deforestation and fragmentation due to historical logging and ongoing large-scale clearance for cattle pasture, and crops such as sugar cane, coffee, and exotic trees, as well as for smallholder agriculture. Clearance of forest for coastal development is another threat within the range of this species.
The species is known from some protected areas (Flavio Baldissera in litt. 2005).
Red List Status
Least Concern (LC)
This species has recently been separated from Rhinella crucifer (Baldissera et al. 2004).
