|Taxonomic Notes:||The taxonomic status of A. planispina and A. palmatus was discussed by Coloma (1997). Records of A. palmatus from Napo Province actually belong to this species (Ecuador Red List Assessment Workshop July 2016).|

Listed as Critically Endangered (Possibly Extinct) because, despite surveys in the area of this species' distribution, it has not been seen since 1985. As such, it is presumed that the species suffered severe declines more than 10 years or three generations ago possibly due to the spread of the chytrid fungus. It is therefore considered to be Possibly Extinct and its population is inferred to be less than 50 mature individuals.
|Date last seen:||1985|
|Previously published Red List assessments:|
|Range Description:||This species is known from the eastern slopes of the Ecuadorian Andes, in Napo province. Records from the Azuay and Morona Santiago provinces that were previously assigned to this species actually correspond to other species (Ecuador Red List Assessment Workshop July 2016). It has been recorded from 1,000–2,000 m asl.|

|Population:||In a previous assessment, it was found that the population of this species had declined dramatically. The last record of this species is from July 1985 (an amplectant pair), despite repeated visits to known (El Reventador) or inferred localities (within its extent of occurrence) (Bustamante 2002). If a population still exists, it is suspected that the population size is less than 50 mature individuals (Ecuador Red List Assessment Workshop July 2016).|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||This species is an inhabitant of humid montane forest. There is no specific information known about breeding, but it is likely to be similar to other Atelopus species, with breeding and larval development taking place in streams.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Movement patterns:||Not a Migrant|
|Use and Trade:||There are no records of this species being utilized.|
|Major Threat(s):||In the past the species suffered a large population reduction probably due to chytridiomycosis. At present, habitat loss due to agriculture (both crops and livestock), logging, mining, and infrastructure development for human settlement, as well as agricultural pollution, are major threats.|
Its distribution range overlaps with Parque Nacional Sumaco Napo-Galeras, Reserva Ecológica Antisana, and Parque Nacional Cayambe-Coca.
Any surviving individuals might need to form the basis for the establishment of an ex situ population.
Surveys are needed to establish whether or not this species is still extant.
