From the IUCN Red List Species Account:

 

Range Description

This species is known from a few localities on the slopes of the Andes in Salta Province, Argentina, and also in Tarija Department, Bolivia, at 1,500-1,600m asl. It probably occurs a little more widely than records indicate.

Habitat and Ecology

It is an arboreal species found in the canopy of montane forests (Yungas). During amplexus, males place eggs in the marsupial pouch on the female's back. The eggs hatch and the larvae develop in the pouch. The females subsequently deposit the larvae in small pools of water on the forest floor where metamorphosis takes place. This species' tolerance to habitat disturbance is not known.

Population

It is a very rare species, but has been collected as recently as 2002 in Argentina.

Population Trend

decreasing

Major Threats

The major threats include selective logging, the clear-cutting of primary forests, introduction of predatory fish (trout), and the alteration of watersheds.

Conservation Actions

Some populations are protected in Parque Nacional Baritú in Argentina, and Reserva Nacional de Flora y Fauna Tariquía in Bolivia.

Red List Status

Vulnerable (VU)

Rationale

Listed as Vulnerable because its Extent of Occurrence is less than 20,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its forest habitat on the Andean slopes in northern Argentina and Boliva.

Taxonomic Notes

This genus has recently been moved from the family Hylidae (Faivovich et al. 2005).
