This species is known only from two localities at altitudes of 1,780 and 1,820m asl on the Pacific versant of the Andes: Tandayapa, in Pichincha Province, northern Ecuador; and La Planda, Nariño Department, in extreme southern Colombia.
Habitat and Ecology
This species lives on vegetation next to streams in humid upper montane forest. It presumably breeds in streams, with the eggs being laid on leaves overhanging the water into which the larvae drop and continue to develop.
It is known only from three specimens. There have been no records since the original description, probably because subsequent records have been assigned to Centrolene lynchi, with which it might be synonymous.
If the threats to this species are the same as those facing C. lynchi, the most severe threat is likely to be the movement of the cloud layer up the mountain sides as a result of climate change, resulting in reduced humidity within the altitudinal range of this species (this process is probably exacerbated by habitat fragmentation). Additional likely threats are: deforestation due to agricultural development, cultivation of illegal crops, fire, logging, and human settlement; introduction of alien predatory fish species in streams; and pollution resulting from the spraying of illegal crops. Chytridiomycosis also cannot be ruled out.
This species occurs in the privately owned nature reserve (the Reserva Natural La Planada) at La Planada, Colombia. Its taxonomic validity needs to be assessed.
