This species is known only from the type locality, at 700m asl in the Serra do Quengo in Jaqueira Municipality, Pernambuco State, north-east Brazil. However, surveys in Pernambuco have been limited to date and this species might occur more widely.
Habitat and Ecology
The type locality of this species is in forest near a small, shallow stream that is about 1m wide and 0.5m deep. Individuals were found on branches 0.5-1m above the ground. Larvae were found in slow-moving parts of the same stream, and a spherical mass of around 30 eggs was found attached to a fallen plant stem under the water.
No information on its population status is currently available.
It is not known whether or not this species is impacted by habitat loss. However, most of the larvae collected exhibited oral disk abnormalities, which have been associated with chytrid fungus infection in some stream-dwelling amphibian species. The species in fact tested positive for Batrachochytrium dendrobatidis (Carnaval et al., 2006).
This species' type locality is in the Reserva Particular do Patrimônio Natural Frei Caneca, a private forest reserve managed by the sugarcane farm and distillation plant Usina Frei Caneca. Given the presence of the chytrid fungus, long-term monitoring of this population is desirable, as are surveys for other populations.
This species was previously within the genus Hyla but has recently been moved to the resurrected genus Hypsiboas (Faivovich et al. 2005).
