Justification:
Listed as Endangered because its Extent of Occurrence is less than 5,000 km2, all individuals are in fewer than five locations, and there is continuing decline in the extent and quality of its habitat on the Amazonian slopes of the Ecuadorian Andes.

| Population: |
It was last recorded in 1979, when five specimens were collected from one site. The Río Azuela site has been revisited several times without locating any individuals.

| Population Trend: |
Decreasing

Habitat and Ecology
[top]
| Habitat and Ecology: |
It lives in cloud forest. The holotype was found on the leaf of a herb over a small stream at night (Lynch and Duellman 1973). Reproduction is presumed to occur via eggs laid on vegetation, with the larvae developing in streams.
|
| Systems: |
Terrestrial; Freshwater |
| Major Threat(s): |
Habitat destruction and degradation is the main threat to this species, primarily due to smallholder farming and logging. At this stage it is not clear whether or not this species might have declined within pristine habitats. Predictions suggest that, in Ecuador, almost half of the habitats suitable for this species have been deforested (Cisneros-Heredia, 2008).

Conservation Actions

| Conservation Actions: |
It is not known to occur in any protected areas, and protection of remaining cloud forest habitats is sorely needed. Further survey work is necessary to determine the current population status of this species.
