This species can be found on the high ridges in the Andes in the region of the Huancabamba Depression in Loja Province (Ciudad de Loja), southern Ecuador, and Piura Department, northern Peru. In Peru it is known only from one site 33km south-west of Huancabamba. It probably occurs more widely than current records suggest, especially in areas between known sites. It is known from altitudes of 2,040-3,000m asl in Ecuador, and from 1,700m asl in Peru.
Habitat and Ecology
This nocturnal and terrestrial species lives in cracks in the ground below the leaf-litter in upper montane forest, but not in old growth forest. It also occurs in areas bordering pastures and other open areas. Reproduction occurs by direct development.
This species’ population status is known only at a few localities, possibly because it is hard to collect. Judging by its calls, it was common in Loja in 2003.
The major threat to this species is habitat destruction and degradation, mainly due to subsistence agriculture.
Given its known habitat and geographic distribution, this species might occur in the Santuario Nacional Tabaconas Namballe, in Peru.
