This species is known only from eight localities on the edges of the Ambato-Riobamba Valley in central Ecuador between 2,560 and 3,700m asl.
Habitat and Ecology
It lives in high-altitude páramo grassland and sub-páramo bush land. It is not known whether or not it tolerates habitat degradation. It is presumed to breed by direct development, but the site of egg deposition is not known.
It is an uncommon species.
The major threat is habitat loss and degradation. At the type locality, for example, patches of natural vegetation have been cleared for agriculture, livestock farming, and pine plantations, and this is believed to be having a serious impact on the species.
It is not known from any protected areas, which makes formal protection of this species' high-altitude habitat a priority.
