From the IUCN Red List Species Account:


Range Description

This species is known from the Amazonian slopes of the Ecuadorian Andes at elevations between 2,600 and 2,800 m asl (Mueses-Cisneros et al. 2010). Individuals were only found in the type locality of Alto La Bonita, Parroquia La Bonita in Provincia de SucumbĂ­os, Ecuador (Mueses-Cisneros et al. 2010). Since it is only known from the type locality its extent of occurrence (EOO) is presumed to be less than 10 km2; however, since the site where this species was found is fairly inaccessible and with habitat in good condition it is believed to possibly have a wider distribution, especially as there are no obvious dispersal barriers in the area (J. Guayasamin pers. comm. November 2011).

Habitat and Ecology

Frogs were collected from montane forests at night perching on bromeliads and bush leafs about 2-2.5 m asl (Mueses-Cisneros et al. 2010). This species breeds by direct development (J. Guayasamin pers. comm. November 2011). Females were found carrying 12-15 eggs approximately (Mueses-Cisneros et al. 2010). Individuals were only found in primary montane forest, which could indicate that the species might not be able to withstand any degree of habitat modification (J. Guayasamin pers. comm November 2011).


This species is considered to be abundant within its known distribution (Mueses-Cisneros et al. 2010).

Population Trend


Major Threats

No potential major threats to this species were observed (J. Guayasamin pers. comm. November 2011).

Conservation Actions

No conservation actions are currently known for this species. More information is needed on this species' distribution, population status and threats.


Red List Status

Least Concern (LC)


Listed as Least Concern because it is likely to have a wider distribution, its habitats are not significantly threatened and it is presumed to have a large population.
