This species is found in the Atlantic Forest of Brazil; from southern Espírito Santo State, through Rio de Janeiro and São Paulo States, to northern Paraná State. It is also possibly found in northeast Argentina, in Misiones and Corrientes Provinces. It can be found from sea level to close to 1,000m asl.
Habitat and Ecology
This species is restricted to lowland Atlantic Forest. Reproduction involves eggs and exotrophic tadpoles in lentic water (Abrunhosa et al., 2006). It is found near and in temporary pools. The species is believed to be fairly tolerant of habitat modification.
It is the most abundantly collected species in Reserva Biológica do Morro Grande (Dixo and Verdade, 2006).
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.
This species is known in Brazil from Parque Nacional da Serra dos Órgãos, Tinguá and Poço das Antas Biological Reserves, Reserva Florestal de Morro Grande and Parque Estadual do Desengano, and possibly Iguazú National Park in Argentina.
Red List Status
Least Concern (LC)
Listed as Least Concern as it has an extent of occurrence far exceeding 20,000 km2, occurs at many localities including a number of protected areas, and is not known to be undergoing significant declines.
This species was removed from synonymy of Rhinella crucifer by Baldissera et al. (2004).
