From the IUCN Red List Species Account:


Range Description

Individuals of this species are known from west-central Brazil, in the southwestern State of Mato Grosso and northwestern State of Mato Grosso do Sul, between 142-221 m asl (Caramaschi 2010). Taking its range as a proxy for extent of occurrence (EOO) this is estimated at 12,853 km2. Given its relatively widespread distribution within the Amazon basin, which still contains suitable habitat, this species may have a wider distribution.

Habitat and Ecology

It inhabits lowland rainforests. Based on information from congeners it is presumed to be a fossorial species that can be found within leaf litter, breeds in ponds and has aquatic larvae (Toledo et al. 2011).


It is known only from the type series. Its population status is currently unknown.

Population Trend


Major Threats

There is no direct information on major threats to this species, although given its widespread occurrence it is possible that there may be localized threats in the form of human settlement development, agriculture, livestock farming and logging.

Conservation Actions

There are no conservation actions currently known for this species. More information is needed on this species' population status, natural history and threats.

Red List Status

Least Concern (LC)


Listed as Least Concern given that it has a widespread distribution over a large area of the Amazon basin which still contains suitable habitat.

Taxonomic Notes

Caramaschi (2010) considered Elachistocleis ovalis a nomen dubium associated to a species inquirenda (a species of doubtful identity requiring further investigation); biological populations in Brazil formerly associated to this name were reassigned to other species.
