This species occurs on the western slopes of the Ecuadorian Andes and the coastal Cordillera in the provinces of Manabí, Guayas, Bolívar, Los Ríos, Azuay, and El Oro. It has been recorded from 70-1,500m asl (Coloma 1995) and has also recently been found in Loja (Almeida 2002).
Habitat and Ecology
It inhabits humid premontane forest, tropical thicket and thorny scrub, and very dry tropical forest (Coloma 1995). Eggs are laid on land in leaf-litter or under rocks, and the larvae are then carried to water by the adults where they develop further.
It is a common species.
The major threats to this species are agricultural development (involving cultivation of crops and rearing of livestock), logging, and creation of wood plantations. Introduced goats are also degrading the species' habitat, which is severely fragmented.
Its geographic range overlaps with Parque Nacional Machalilla, Reserva Ecológica Manglares Churute, and Reserva Ecológica Arenillas.
Red List Status
Near Threatened (NT)
Listed as Near Threatened because this species is probably in significant decline (but probably at a rate of less than 30% over ten years) because of widespread habitat loss through much of its range, thus making the species close to qualifying for Vulnerable.
