This species occurs on Chimantá tepui, Jaua tepui and Mount Roraima in Bolívar state, southeastern Venezuela, and Mount Ayanganna in western Guyana. It occurs at 1,500-2,151m asl.
Habitat and Ecology
It is a diurnal toad living at the borders of slow-flowing streams in high montane tepui habitats. It calls from holes in leaf-litter or from between trunks or in crevices between rocks near montane streams. The tadpoles live in the substrate at the bottom of small ponds adjacent to flowing waters (the spiracle protrudes from the substrate enabling respiration).
It is a relatively common species.
Tourism could be a threat in Mount Roraima, but otherwise there are no significant threats.
It occurs in Canaima National Park (Venezuela). Taxonomic research is needed to resolve the identity of specimens from Jaua-Sarisariñama.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its probable wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
This taxon was long considered a subspecies of Otophryne robusta, until the taxonomic treatment by Campbell and Clarke (1998).
