Geographic Range [top]

Range Description: This species was recorded from the Provinces of Esmeraldas, Imbabura, Cotopaxi, and Pichincha, on the north-western versant of the Ecuadorian Andes, at elevations of 200-2,500m asl. Records from the western slope of the Cordillera Occidental, Valle del Cauca Department, in Colombia, refer to an unidentified, probably un-named species.

Population [top]

Population: The species appears to be extinct, with no records in Ecuador since 1989, despite extensive surveys in suitable habitat.

Habitat and Ecology [top]

Habitat and Ecology: This was a terrestrial species of lowland and montane tropical rainforests. It was a stream breeding species.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): The decline in Ecuador is unexplained, and is possibly due to the disease chytridiomycosis, although this seems unusual given that the species was also found at lower elevations where chytridiomycosis is often not considered to be a threat. Other possible factors contributing to the extinction of this species include general climate change, pollution and habitat loss.

Conservation Actions [top]

Conservation Actions: The range of this species overlapped with the Reserva Ecológica Cotacachi-Cayapas and possibly reached the northern limit of the Reserva Ecológica Los Illinizas.
