This species is endemic to Cajamarca and Amazonas Departments, northern Peru. It is present at two localities (at 1,138m and 1,750m asl) on the eastern slopes of the Cordillera del Condór; a single locality (at 1,300m asl) on the southern edge of the Cordillera del Condór; and at altitudes of 1,830m asl and 2,400m asl in the northern part of the Cordillera Central. This species is believed to have a continuous distribution between the Cordillera del Condór and the Cordillera Central, and might prove to be more widespread.
Habitat and Ecology
It can be found in humid and semi-arid montane forest, but it is not known if it can occur in modified habitats. The holotype was collected in an arboreal bromeliad by day in semi-arid forest. Specimens from the eastern slopes of the Cordillera del Condór were found on low vegetation at night in humid montane forest. This species breeds by direct development.
There is no information on its population status. Records of three adult males and one adult female were used to describe this species.
It is threatened in the south of its range by deforestation through increased agricultural activity (rearing of livestock and cultivation of crops), by selective wood extraction and by increasing colonization of the area.
It is present in the Zona Reservada Santiago-Comaina, and is also believed to occur in the Zona Reservada Cordillera de Colán. Further research into this species is required.
