This species has been recorded from different valleys in Huánuco, on the Andean slopes of central Peru (E. Lehr, pers. comm. 2008). It has been reported from localities such as Conchamarca, Yaurin, Huancamonte and Maraypata (Province of Ambo, Department of Huánuco). It has an altitudinal range of 3030-3430 masl.
Habitat and Ecology
It occurs in Polylepis forest ("Queñoales"), montane forest, and pasture with bushes ("Matorral Humedo"); it is also present in disturbed areas where water is available. It has been observed during the day on the ground and in the leaf litter, while at night it is found on leaves. Lehr (2006) reports that the species is active at night on the vegetation, between 0.3–1.5 m above ground.
It breeds by direct development.
The species is common in the leaf litter during daytime and at night on plants (E. Lehr, pers. comm. 2008).
The Polylepis forests have been reduced drastically by human activities over the years (primarily due to potato farming and cattle ranching).
The local people of Maraypata informally protect the remaining forest, but given the continuing rate of forest loss there might well be a need for the establishment of a formal protected area and an official management plan.
