This species is currently known only from the general vicinity of Cerro Yapacana at around 100m asl in Amazonas state, southern Venezuela. The type specimen comes from the non-specific location of "Upper Amazon". It presumably occurs in adjacent Colombia and Brazil, and is likely to occur much more widely.
Habitat and Ecology
It is a large, semi-aquatic species of tropical lowland rainforests. It lives at edge of rivers, where it burrows. It is a viviparous species, probably in water. Its adaptability to secondary habitats is not known, but there is very little human impact within its range.
It is very common in certain localities within its Venezuelan distribution.
It is unlikely to be significantly threatened, but mining activities in the Yapacana area might affect population there.
It occurs in the Neblina National Park, Venezuela.
Red List Status
Least Concern (LC)
Listed as Least Concern since, although its currently known Extent of Occurrence is probably less than 20,000 km2, it occurs in an area of extensive, suitable habitat which appears not to be under serious threat, it has a presumed large population, and it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
