This species is known from the Amazon basin of Colombia, the Guianas, Ecuador, Peru, Bolivia and Brazil. Records from southern Venezuela are misidentified specimens of L. riveroi. It has an altitudinal range of 0-500m asl.
Habitat and Ecology
This species can be found in leaf-litter on forest floor and in swamps in tropical rainforest; also found on the edges of clearings and in more open areas in forest. Reproduction occurs in semi-permanent waterbodies. Males call from within holes in the ground. Eggs are found in foam nests and tadpoles are found in lentic water. Tadpoles resemble those of Hypsiboas geographicus and Leptodactylus riveroi, but do not form schools (Lima, 1992). In Guyana, the species was observed to prefer habitats characterized by an open canopy and the presence of small and shallow, but comparatively persistent, aquatic habitats, often occurring in disturbed habitats and to a lesser degree within primary forest (Ernst et al., 2007).
It is common to locally common throughout its range.
There are no major threats.
Many populations are within protected areas.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining to qualify for listing in a more threatened category.
