This species is known from the Amazon basin in Brazil, Colombia and Venezuela, at altitudes from 90-450m asl. In the Brazilian Amazon, it is known only from fragmented forests around Manaus, in Amazonas state.
Habitat and Ecology
It is a nocturnal, terrestrial species found at regular intervals on the forest floor and along the banks of rivers in tropical rainforest. The eggs are laid in foam nests, and the tadpoles develop in lentic water. The tadpoles resemble those of L. rhodomystax and Hypsiboas geographicus, forming congregations.
It is not a common species.
Mining and associated water pollution is a major threat to the species' habitat.
Its range includes several protected areas.
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.
