This species occurs on the slopes of the Andes in Jujuy Province, Argentina, at mid elevations from 1,550-2,600m asl.
Habitat and Ecology
It is a terrestrial species that lives in montane forests (Yungas), and occurs arboreally in tree crowns, tree holes and rock crevices. Although there are records of this species persisting in moderately disturbed habitats for a few decades, intensification of the disturbance eventually led to the species' disappearance in these areas. Males call from burrows, and during amplexus, males place eggs in the marsupial pouch on the female's back. The eggs hatch and the larvae develop in the pouch, which is also where they develop into froglets.
It is very rare, but has been collected as recently as 2002.
The major threat is habitat loss, mainly due to selective logging and clear cutting of primary forests.
Some populations are protected in Parque Nacional Calilegua, but there is a need for additional protection of Yungas habitat in the range of this species.
Red List Status
Listed as Endangered because its Extent of Occurrence is less than 5,000km2, all individuals are in fewer than five locations, and there is continuing decline in the extent and quality of its habitat in Jujuy Province, Argentina.
This genus has recently been moved from the family Hylidae (Faivovich et al. 2005).
