This species is known from a narrow altitudinal zone (1,140-1,300m asl) on the eastern slopes of the Andes in the vicinity of Volcán Reventador and in the Río Pastaza trench, in Napo, Orellana and Pastaza Provinces, Ecuador.
Habitat and Ecology
It occurs in premontane forest, where the annual mean precipitation is 2,000-4,000mm and the annual mean temperature is 18-24°C. Reproduction probably occurs by the females laying the eggs on the ground, with the males taking the larvae to streams for their development.
It was formerly abundant, at least judging by the large numbers of specimens in museums, but there is little recent information.
Habitat destruction and degradation, mainly due to agricultural expansion (involving crops, plantations and livestock) and logging, is the main threat to this species. Its narrow altitudinal range might leave it vulnerable to the effects of climate change.
Its distribution range overlaps with several protected areas, including Parque Nacional Sumaco Napo-Galeras, Parque Nacional Llanganatis, the Reserva Ecológica Antisana, and the Reserva Ecológica Cayambe-Coca. This species is in need of close population monitoring.
Red List Status
Listed as Endangered because its Extent of Occurrence is less than 5,000 km2, all individuals are in fewer than five locations, and there is continuing decline in the extent and quality of its habitat on the Amazonian slopes of the Ecuadorian Andes.
Molecular data suggest that Allobates kingsburyi is a species complex (L.A. Coloma pers. comm.).
