From the IUCN Red List Species Account:


Range Description

This is a little-known species, currently known only from Tutumbaro (at 1,840m asl) on the Río Piene, Ayacucho Department, in southern Peru. It might be more widespread than this.

Habitat and Ecology

The type locality is a disturbed cloud forest in a river valley with bamboo, ferns and elephant's ear plants. The individuals were recorded calling at night from the upper sides of leaves of herbaceous vegetation and elephant's ear plants within 1m of a slow stream. Eggs are presumably laid on leaves, with larval development in streams.


There is no information on the population status of this species, which has been collected only once. Four adult males were used to describe this species.

Population Trend


Major Threats

The threats to this species are not known. The area in general is subject to loss and degradation of habitats due to human colonization and agricultural development.

Conservation Actions

Further research is needed into this little-known species, for example regarding the potential impacts of localized climate change and possible infection with the chytrid fungus.
