This species is known from the Guianan Orinoco drainage of Venezuela north to the Río Orinoco (in Bolívar and Amazonas States), east into Guyana to the Essequibo River, south into extreme northern Brazil, and west into eastern Amazonian Colombia. In Venezuela it has been recorded from sea level up to 500m asl.
Habitat and Ecology
This brightly coloured diurnal frog is found in leaf-litter, on the ground, on open rocks, near rivers and rivulets, under logs and on trunks of fallen or inclined vegetation in tropical rainforests. During the dry season, specimens congregate under rocks and fallen tree-trunks. Eggs are laid out of water, and the tadpoles are then carried to streams where they develop further. It is adaptable to some habitat disturbance.
It is a common species.
Agriculture, logging and fire are threats to the species' habitat. It is also in the international pet trade.
Some populations live within protected areas south of the Orinoco river in Venezuela. It is considered in the Venezuelan Red Data Book as Lower Risk, Least Concern. It is listed under Appendix II of CITES (listed 22-10-1987), and in the European Community, it is listed under regulation 338/97, Annex B, listed on 01-06-1997 (Walls 1994; Cites web-site). It breeds easily in captivity.
