Population [top]

Population:There is little information on the population size and trends of this species.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This is a riparian, semi-aquatic species of rocky high-gradient streams in undisturbed cloud forests. It is unknown if it can occur in disturbed habitat. Reproduction occurs by larval development, as with other congeners.
Systems:Terrestrial; Freshwater
Movement patterns:Not a Migrant

Use and Trade [top]

Use and Trade: Aquatic species from this genus are known to be harvested in large numbers for human consumption and medicinal uses, and is often sold at local markets (Lehr 2005).

Threats [top]

Major Threat(s): Outside existing protected areas, the major threat to this species is likely deforestation, though this species is not known to exist outside of the Cordillera de Colán National Sanctuary. Similar to its congeners, this species is likely to be very susceptible to chytridiomycosis caused by Batrachochytrium dendrobatidis. The pathogen has yet to be reported from this species; however there are several reports of infections in congeners in southern Peru (Seimon et al. 2005, Catenazzi et al. 2011), and chytridiomycosis has been implicated as one of the causes of the disappearance of Telmatobius niger in Ecuador.

Conservation Actions [top]

Conservation Actions: Conservation Actions
It occurs within the Cordillera de Colán National Sanctuary. 

Research Needed
Further survey work is needed to determine if it occurs outside the vicinity of the type locality. More information is needed on this species' distribution, population status, natural history, and threats. Careful population monitoring is necessary, particularly given the risk of chytridiomycosis.
