This species is confined to the central region of the west flank of Cordillera Oriental in the Departments of Santander and Boyacá, Colombia. It is found between elevations of 1,700 and 2,400 m Asl (Acosta-Galvis and Gutierrez-Lamus 2012). The EOO of this species is 6,849 km2 and it is considered to occur in three threat-defined locations.
Habitat and Ecology
This nocturnal species is found near streams in primary and secondary undisturbed, humid montane forest (Acosta-Galvis and Gutierrez-Lamus 2012). Individuals have been found standing on low leaves (0.50–1.30 m) of Araceae, Melastomataceae and ferns. It is expected to reproduce by direct development, as with other congeners. This species is not tolerant to habitat disturbance and so anthropogenic impacts on the specific habitat of this species would be particularly detrimental.
This is an apparently common species near the type locality (Encino municipality, Santander) and the population is considered to be stable (Colombia Red List Assessment Workshop August 2016). Recently 18 individuals were collected in Corregimiento Virulín, municipio de Charalá, Santander (F. Meza Joya pers. comm. 2016).
Both degradation and fragmentation of this species' habitat has been reported (Acosta-Galvis and Gutierrez-Lamus 2012) due to logging, mining and agriculture. Batrachochytrium dendrobatidis has also been reported within the species' range (Ruiz and Rueda-Almonacid 2008).
This species occurs in several protected areas, including Distrito Regional de Manejo Integrado Serranía de los Yariguies and Parque Nacional Regional Bosques Andinos Húmedos El Rasgón in Santander Department, Colombia.
Habitat management to minimize human destruction and degradation at sites where this species is known to occur is recommended.
More information is needed on this species' distribution, population status, ecology, and threats.
Red List Status
Listed as Vulnerable, as this species has an extent of occurrence (EOO) of 6,849 km2, it occurs in three threat-defined locations, and there is a continuing decline in the quality of its habitat. Since this species requires undisturbed old growth forest and is suspected to be susceptible to habitat modifications, it is unlikely to be able to adapt to such changes. In addition, Batrachochytrium dendrobatidis has been reported within the species' distribution which could potentially have detrimental impacts on the population.
