This species ranges from eastern Venezuela (in Bolívar State), east to central Suriname. It is presumed to occur in Guyana, but this has not been confirmed. It has been recorded from 100-400m asl.
Habitat and Ecology
This is a subterranean species in tropical moist environments, especially lowland rainforest. It has also been found in secondary habitats.
There is no information on the population status of this species; it is known only from isolated records.
It occurs in an area of low human impact, and since it is also somewhat adaptable it is unlikely to be facing any significant threats. Mining and associated water pollution might be local threats.
It probably occurs in several protected areas in Suriname, Guyana and Venezuela. The conspecificity of the specimens from Venezuela and Suriname needs to be evaluated.
Red List Status
Data Deficient (DD)
Listed as Data Deficient in view of continuing uncertainty as to its taxonomic status.
The conspecificity of the specimens from Venezuela and Suriname is not certain.
