This species is known from sea level to 300m asl along the coasts of north-eastern São Paulo and south-western Rio de Janeiro States, south-east Brazil.
Habitat and Ecology
This species occurs near very straight, flowing streams inside lowland Atlantic forest. During the day, adults can be found in bromeliads in high trees or in coiled leaves of Musaceae and Marantaceae vegetation. Males call at night from similar locations, and bushes or banana trees. Breeding is concentrated from August to January. The larvae are lotic-benthic, hiding between stones and pebbles on the sandy substrate of narrow canopied forest streams.
No information is currently available on its population status.
The Atlantic forest in which this species occurs 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. Forest is increasingly being cleared for coastal development projects.
This species is not known to occur in any protected areas, and improved habitat protection is clearly needed.
This species was previously within the genus Hyla but has recently been moved to the genus Aplastodiscus (Faivovich et al. 2005).
