Range Description

This species' geographic range is the lower northeastern slopes and foothills of the Andes, where it is known from Peru in the region of Yurimaguas (Departamentos: Amazonas, Loreto, San Martin) and from southeastern Ecuador. It has been recorded between 500 and 1,550m asl in Ecuador (Coloma 1995). In Peru it occurs mainly at lower elevations, between 325 and 810 m asl (Duellman 2004).

Habitat and Ecology

This frog's distribution lies within biomes described by Coloma (1995) as "Very Humid Premontane Forest and Humid Premontane Forest" (annual mean precipitation: 2,000–4,000 mm and 1,000–2,000 mm respectively; annual mean temperature: 18–24ºC). The species has also been recorded from dry forest in the vicinity of Chiriaco, Peru (Duellman 2004).

The Los Tayos rocket frog is mostly restricted to rocky stream habitats and waterfalls, where it is active primarily by day but also at night (Duellman 2004). Where it occurs, this species appears to be the only poison dart frog associated with these habitats (Duellman 2004). Eggs are laid on land. Larvae are transported to streams by adults where they develop in quiet pools in or adjacent to the watercourse (Duellman 2004). In one reported case, a male was transporting 12 tadpoles (Duellman 2004). The species is known to occur in modified and lightly degraded habitat, including rural gardens and cutover forest.


This species is not rare where it occurs.
