This species occurs below 800m asl in north-western Ecuador, and across the border in Colombia near Altaquer in Nariño Department. It also occurs on Gorgona Island, situated 56km off Colombia’s Pacific coast.
Habitat and Ecology
It inhabits primary and secondary lowland forest, not occurring in open areas. It is sometimes, but not always, found near streams. Specimens have been found at night on low vegetation. It is presumed to breed by direct development, but the site of egg deposition is not known.
It is an uncommon species.
The major threats are likely to include agricultural development (livestock, plantations, and illegal crops), logging, and human settlement, and pollution resulting from the spraying of illegal crops.
In Ecuador, its geographic range overlaps with the Reserva Ecológica Cotacachi-Cayapas. In Colombia it occurs in Parque Nacional Natural Gorgona.
