This species is known from central coastal French Guiana. It has been recorded from 5-200m asl.
Habitat and Ecology
This species is found near fast-flowing small streams and creeks in lowland rainforest; it is not known from any disturbed habitats. Eggs are laid in the water and the tadpoles adhere to rocks.
It is a locally common species (Lescure and Marty 2001), and was recorded as recently as 2000.
There are no current major threats. However, it is potentially at risk from chytridiomycosis, although it occurs at low altitudes (which might afford it a degree of protection from this disease). An illegal international pet trade exists for this species, but it is not a threat to the species as a whole.
The range of the species includes several nature reserves. 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.
