This species is known only from the type locality, Río Pastaza, in Pastaza Province, Ecuador, at 1,000m asl.
Habitat and Ecology
This species is an inhabitant of humid montane forest. There is no specific information known about its breeding biology, but it is likely to be similar to other Atelopus species, and to be a larval developer.
Its population status is not known, and it is not known to have been recorded since 1937.
The major threat to this species is likely to be chytridiomycosis, leading to a catastrophic population decline, as has occurred in many other montane species of Atelopus. Agriculture, involving both crops and livestock, as well as logging, mining (in the future), and wood plantations are major threats to this species’ habitat.
It is not known to occur in any protected areas.
Red List Status
Data Deficient (DD)
Records other than from the type locality (e.g. Peters 1973) are considered here to refer to Atelopus planispina, which this species is probably a synonym of. The taxonomic status of A. planispina and A. palmatus was discussed by Coloma (1997).
