This species is known from north-eastern coastal and central French Guiana. It occurs from sea level up to 300m asl.
Habitat and Ecology
This species is known from the proximity of fast-flowing small streams in lowland primary forest. It has not been recorded outside primary forest. Embryonic and larval development occurs in water.
This is a common species, although it is not common in Mont Grand Matoury and Matoury region. It has been recorded as recently as 2000.
There are no present threats to this species, but future threats will most likely include shifting agriculture and clear-cutting of the forests. Although illegal, there is still some collection for the pet trade, but at present this is not a major threat to the species. This species probably occurs at elevations below the altitude at which chytridiomycosis seems prevalent, though this nonetheless remains a potential future threat.
The range of this species includes Matoury Nature Reserve and Kaw Nature Reserve. Continued population monitoring is required, especially in light of the potential threat of chytridiomycosis.
Red List Status
Listed as Vulnerable because of a projected population decline, estimated to be more than 30% over the next ten years, inferred from declines in other Atelopus species in the same region, probably due to chytridiomycosis.
Atelopus spumarius barbotini has been suggested to represent a junior synonym of this species (Kok 2000).
