This species is only known from the eastern base of Volcán Reventador, south-west of the Río Azuela bridge on the Quito-Lago Agrio road, in Napo Province, at 1,700m asl, on the Amazonian versant of the Andes in Ecuador.
Habitat and Ecology
The type locality is a forested ridge, which has a relatively low canopy and is exceedingly dense in most places. This forest is cool and very damp, with a conspicuous moss layer and many epiphytes on the tree trunks. Specimens have been found by day, on or close to the ground, in the forest and in adjacent new clearings. The eggs are laid on the ground, and the tadpoles are carried on the back of the adults one by one to bromeliads, where they develop.
It no longer survives at its only known locality, but there is a small chance that it survives elsewhere in localities that have not yet been surveyed.
Patches of forest at the type locality have been cleared for agriculture and livestock farming. The species also could have been affected by the synergistic effects of chytridiomycosis and climate change.
The distribution range of the species might overlap with Reserva Ecológica Cayambe-Coca, but its presence there has not been confirmed. There is an urgent need for further survey work to determine whether or not this species might survive at other sites near the type locality.
