Population [top]

Population:It was a locally abundant species. It has not been recorded since 1998, when a few individuals were collected from Serranía de los Paraguas (Lynch and Grant 1998). During a three-day return visit to the type locality in 2004, there was an apparent absence of this species (Grant and Bolívar-G 2014). Recent surveys from at least three localities were unable to detect this species (W. Bolívar pers. comm. August 2016).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:Unknown

Habitat and Ecology [top]

Habitat and Ecology:It occurs along streams in sub-Andean and Andean primary or good secondary forest, and has not been recorded outside forest habitat. Its breeding habits are not known, though it is likely to take place in streams.
Systems:Terrestrial; Freshwater
Continuing decline in area, extent and/or quality of habitat:Yes
Movement patterns:Not a Migrant

Major Threat(s): Major threats to this species include habitat loss due to the expansion of agriculture activities, cattle raising, logging, and mining activities.

Conservation Actions [top]

Conservation Actions: Conservation Actions
This species occurs in Parque Nacional Natural Munchique and probably occurs in Parque Nacional Natural Farallones de Cali. The Corporación Autónoma Regional del Valle del Cauca (CVC) has classified this species as Critically Endangered (S1), suggesting it is at very high risk of extinction due to its extreme scarcity, severe declines or other factors (Castro-Herrera and Bolívar-G 2010). 

Conservation Needed
Improved protection of the species habitat is required.

Research Needed
Further research on population trends, ecology and distribution are recommended for the species.
