This species is known from Santo Domingo de los Colorados (the type locality), and from near to Mindo, in Pichincha Province in north-western Ecuador. It occurs at around 1,500m asl.
Habitat and Ecology
It is known to be associated with montane forests. The eggs are presumably laid on land, with the hatching larvae falling into streams to complete their development.
The population status of this species is unknown.
There is no information on specific threats to this species. Possible threats include loss of mountain forest for livestock rearing, agricultural activities and water pollution, but the significance of these depends on the ability of this species to adapt to habitat change.
The taxonomic status of this species needs to be reviewed. It occurs in the protected area formed by the Mindo-Nambillo Protected Forest.

Data Deficient (DD)
Listed as Data Deficient in view of continuing doubts as to its taxonomic validity as well as absence of recent information on its extent of occurrence, status and ecological requirements.
