Population [top]

Population:The species is apparently common, but there is no information about the population trend. Specimens were registered between 2013–2017, during several week long surveys, in the western flank of the Cordillera Oriental, Santander Department. There is no recent information about this species in Norte de Santander (F. L. Meza-Joya pers. comm. March 2017).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It lives in streams in cloud forest, and near streams. The specimens that have been collected near streams have been found in a habitat with certain degree of disturbance, but always associated with pockets of forest (F. L. Meza-Joya pers. comm. March 2017). Duellman (1989) described the habitats as ravine containing remnants of cloud forest. Eggs are laid on vegetation and the larvae develop in water.
Systems:Terrestrial; Freshwater
Continuing decline in area, extent and/or quality of habitat:Yes
Movement patterns:Not a Migrant

Use and Trade [top]

Use and Trade: There are no records of this species being utilized.

Threats [top]

Major Threat(s): Threats to this species include habitat loss due to agricultural cultivation and cattle ranching, gold mining, and predation from introduced trout (Oncorhynchus mykiss).
