This species occurs in northern French Guiana, Suriname, Guyana and Brazil. A dot-map of distribution in French Guiana is provided in Lescure and Marty (2001). It occurs up to 150m asl.
Habitat and Ecology
It is a subterranean species in lowland rainforest. It is presumed that courtship, mating and fertilisation take place on land and following brooding by the female, the larvae hatch and drop into streams, like other members of its family. It is not known if this species can occur in degraded habitats.
The population status of this species is unknown.
It occurs in an area of very limited human impact, and it is therefore unlikely to be significantly threatened.
It occurs in several protected areas.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
This species might consist of more than one species (M. Wilkinson pers. comm).
