From the IUCN Red List Species Account:


Range Description

This species occurs on the western slopes of the Cordillera Oriental, in the Departments of Santander and Norte de Santander, Colombia, at 1,050–3,000 m Asl. Its extent of EOO is 3,435 km2 and it is considered to occur at six threat-defined locations.

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.


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).

Population Trend


Major Threats

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

Conservation Actions

Conservation Actions
It occurs in Reserva Biológica Cachalú, Santuario de Flora y Fauna Guanentá Alto Río Fonce, and Estación Experimental y Demostrativa el Rasgón.

Conservation Needed
A higher conservation category is recommended for the known protected areas to guarantee better protection of the sites and the species (F. L. Meza-Joya pers. comm. March 2017).

Research Needed
More information is needed on this species' distribution, population status, natural history, and threats.

Red List Status

Vulnerable (VU)


Listed as Vulnerable because its extent of occurrence (EOO) is 3,435 km2, it is considered to occur in six locations in the Cordillera Oriental, including protected sites as well as unprotected areas affected by ongoing habitat loss and degradation due to farming activities, mining activities and the presence of trout in the water bodies.

Taxonomic Notes

This species was previously within the genus Hyla but has recently been moved to the resurrected genus Hyloscirtus (Faivovich et al. 2005).
