This species is known from the vicinity of the type locality of Ullilen, Province of Mariscal Cáceres, San Martín Region, Peru (Duellman et al. 2006). It occurs from 3,000–3,300 m asl.
Habitat and Ecology
This species is found in montane grassland with bushes (Baccharis) and very humid montane forest. Individuals have been found at night on the bases of bunch grass and on a rock. It is presumed to breed by direct development. In February 2008 an egg clutch containing 14 eggs was found amidst the grass. This was the only species found in this area and the hatchlings resembled adults of this species (P. Venegas pers. comm. 2008).
The species is only known from the type series, comprised three specimens.
The threats to this species are unknown, although there is regional destruction and loss of habitats for livestock rearing and selective wood extraction in the area, and these threats could affect this species.
It occurs in Los Chilcos Private Conservation Area, designated in 2012. No conservation actions are currently in place for this species and its immediate habitat.
More information is needed on this species' distribution, population status, ecology, and threats.
