It is found in the Mira River drainage in extreme northern Ecuador and in adjacent southern Colombia (Nariño, Cauca, and Valle del Cauca Departments) in foothills and lower cloud forest on the Pacific lowlands and slopes of the Cordillera Occidental.

Groin, anterior and posterior surfaces of thighs are dull yellow with black reticulation.

Iris is bright copper with black flecks and a brown horizontal streak.

It is nocturnal, sitting on rocks, very steep cliffs, or in rocky crevices alongside streams.

Habitat loss caused by agricultural development, logging, and human settlement is probably the main threat to it.
