This species was formerly known only from three localities on the eastern slopes of the Cordillera Central in San Martín Region, northern Peru. It is now also known from several scattered localities in the Regions of Loreto, Amazonas, Huánuco and Juniín (Duellman and Lehr 2009). It occurs through a relatively wide altitudinal range, from 140–1,200 m asl, and consequently might range much more widely. Taxonomic work is needed given the species' wide range (E. Lehr pers. comm. December 2017).
Habitat and Ecology
This species inhabits tropical moist lowland and lower montane rainforest. Individuals have been collected at night on low vegetation. Reproduction is by direct development.
The population status of this species is unknown, however it is relatively common in museum collections.
There is localized deforestation and loss of habitat in the area through an increase in agricultural activity, selective wood extraction and human settlement, however there is plenty of suitable habitat remaining (E. Lehr pers. comm. December 2017).
It occurs in Bosque de Protección Alto Mayo and Pacaya-Samiria National Reserve.
Taxonomic work is needed to determine if this form is a complex of more than one species. More information is needed on this species' distribution, population status, and trends.
Red List Status
Data Deficient (DD)
Listed as Least Concern in view of its wide distribution and presumed large population.
