From the IUCN Red List Species Account:

 

Range Description

This species occurs on the eastern slopes of Sierra del Aconquija, Sierra de Medina and Sierra de Taficillo (near Tucumán), in north-western Argentina, in Catamarca, Tucumán and Salta provinces, at 1,500-2,000m asl. It might occur more widely, including in Bolivia.

Habitat and Ecology

It is an arboreal species found in the tree 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. The most recent record is from 1995, but there has been no recent survey work.

Population Trend

decreasing

Major Threats

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 probably protected in Parque Nacional Los Alisos.

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 in Catamarca, Tucumán and Salta Provinces, Argentina.

Taxonomic Notes

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