This species is known was formerly known only from the type locality in Rodriguez de Mendoza Province in Amazonas Region, Peru (Duellman and Schulte 1992). It is now also known from Pedro Ruiz Gallo in Bongará Province, Amazonas Region, and Bosque de Protección Alto Mayo, Rioja Province, San Martín Region (J.C. Cusi pers. comm. April 2017, R. Santa Cruz pers. comm. April 2017). It occurs from 2,400–2,920 m asl, its estimated extent of occurrence (EOO) is 2,507 km2 and it is considered to occur at three threat-defined locations.
Habitat and Ecology
This arboreal species inhabits montane tropical rainforest, where individuals have been found in bromeliads and palm leaves. Its breeding habits are not known, though it presumably breeds by larval development.
There is little information on the population size and trends of this species. One individual was recorded over six person/hours in Bosque Protección Alto Mayo in October 2016 (J.C. Cusi pers. comm. April 2017). However, due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.
The species is threatened by ongoing habitat loss caused by livestock farming.
It has been recorded from Bosque de Protección Alto Mayo.
This species would likely benefit from improved habitat protection at sites where it is known to occur.
More information is needed on this species' distribution, population status, ecology, and threats.
Red List Status
Data Deficient (DD)
Listed as Endangered because its extent of occurrence (EOO) is 2,507 km2, it occurs in three threat-defined locations, and there is continuing decline in the extent and quality of its habitat in the northern Peruvian Andes.
