This species is known from Valle del Cauca Department, northwards through Choco and Risaralda departments to Antioquia Department, on the western flank of the western Andes, in Colombia, between 900 and 1,450m asl. It probably occurs more widely.
Habitat and Ecology
It occurs in rainforests and sub-Andean forest, and is often found on vegetation along streams (being restricted to streams with canopy cover). It lays its eggs on the upper surface of leaves and when hatched the tadpoles drop into the stream below.
It can be locally common in suitable habitat.
The major threats are habitat fragmentation and loss, due to the expansion of agriculture (cattle raising and planting of illegal crops), and water pollution.
The range of the species includes Parque Nacional Natural Orquideas.
