This species is known from Pichinca and Esmeraldas provinces, in the north-western versant of the Andes of Ecuador, between 700 and 2,200m asl. It is known from more than ten localities.
Habitat and Ecology
This species is an inhabitant of lowland rainforest and humid montane forest. Eggs are laid in strings in streams, and tadpoles attach themselves to rocks.
There is no current information on the population status of this species; it was last recorded in 1989, despite survey efforts, suggesting a serious population decrease.
The major threat is likely to be a catastrophic decline, due to chytridiomycosis, as has occurred in many other species of Atelopus. Agriculture, both crops and livestock, as well as logging, are also major threats to the species’ habitat, and very little suitable habitat remains.
The range of this species overlaps Reserva Ecológica Cotacachi-Cayapas and just reaches the northern limit of Reserva Ecológica Los Illinizas. Additional survey work is urgently needed to determine whether or not this species still persists. In view of the severe risk of chytridiomycosis, surviving individuals might need to form the basis for the establishment of an ex-situ population.
