This species occurs mainly in the lowlands of northern Colombia, including the Middle Magdalena Valley, and extending eastwards to northwestern Venezuela (probably in southwestern Zulia State). There is an isolated population of the Pacific versant of central Panama. It is a low-altitude species.
Habitat and Ecology
There is little information. It is a terrestrial species of lowland forests, and possibly also savannahs. Its ability to adapt to secondary habitats is not known. It breeds in temporary pools.
There is little information, but it appears to be uncommon.
It is presumably affected by ongoing habitat loss.
It is likely to occur in some protected areas, but this is not confirmed.
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.
It is possible that this species is a synonym of Elachistocleis ovalis, and it was treated as such by Kenny (1969). However, here we treat them as separate, pending resolution of this problem.
