From the IUCN Red List Species Account:


Range Description

This species is known from various geographic localities within Región Loreto and one in Región San Martín, both in the Amazonian lowlands of northern Peru (Lehr et al. 2009). It has been recorded from 101-218 m asl (G. Gagliardi pers. comm. January 2013). Due to its wide distribution in northern Peru this species is also considered likely to be distributed in Ecuador and Colombia (Lehr et al. 2009), and possibly also Brazil.

Habitat and Ecology

It occurs in closed-canopy primary and secondary lowland tropical forest (Lehr et al. 2009). Individuals have been found on the ground at night (Lehr et al. 2009). Congeners are known to call from low vegetation at night (Rodríguez and Duellman 1994). As with other congeners, it is presumed to breed by direct development.


The type series is comprised of seven specimens (Lehr et al. 2009), although there are additional, more recent records (G. Gagliardi pers. comm. January 2013), suggesting that the species may be relatively common.

Population Trend


Major Threats

There is some localized habitat loss due to general human activities such as logging, colonization and agriculture (crops, livestock); however, given this species' vast range, there are no known significant threats to its global population.

Conservation Actions

It is not known to occur in any protected area; however, given its widespread distribution it is possible that it may occur within one or more protected areas. Further research is needed into the distribution and population status of this species.

Red List Status

Least Concern (LC)


Listed as Least Concern due to its wide distribution in Peru and potential presence in neighbouring Brazil, Ecuador and Colombia and there are no significant threats to give any cause for concern.
