Range Description

This species occurs on the oriental slope of the Andes, and is known only from the type locality: "Parjacti, 83.2km by road north-eastern Cochabamba, on road to Villa Tunari, Chapare Province, Department of Cochabamba, Bolivia, elevation approximately 2,044m" (Reynolds and Foster 1992).

Habitat and Ecology

It is an arboreal forest species, reported in the Yungas forest (Reynolds and Foster 1992; De la Riva et al. 2000). There is no information on breeding, though it is likely to be a larval developer in water, like other species of the genus.

Taxonomic Notes

De la Riva et al. (2000) registered a slight doubt as to the taxonomic validity of the species. Faivovich and De la Riva (2006), however, continue to recognize it as a valid species, pending a revision of populations associated with the name Hyloscirtus armatus. In the Hyloscirtus armatus group according to Faivovich and De la Riva (2006).
