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.
