This species is mostly found in the central eastern coastal region of Bahia State, Brazil, although an Atlantic forest population is also present in Santa Terezinha Municipality in eastern Bahia. The altitudinal range of this species is approximately 20-720m asl, and it probably occurs at least a little more widely than is currently known.
Habitat and Ecology
This is a species generally associated with tall Restinga (coastal) forest that has also been collected in little-disturbed primary Atlantic forest. The Restinga vegetation is mostly large trees with a dense understorey on a sandy substrate. Individuals can be found calling from bromeliads. Breeding takes place in the slow backwaters of fast-flowing streams.
The population status of this species is not known.
It is probably threatened by disturbance of the Restinga forests due to agricultural development, logging and development of infrastructure for tourism and human settlement.
It is not known if it is present in any protected areas.
This species was previously within the genus Hyla but has recently been moved to the genus Aplastodiscus (Faivovich et al. 2005).
