Geographic Range [top]

Range Description:This species is known only from the type locality: the eastern slope of the Abra Pardo de Miguel, the eastern-most ridge of the Cordillera Central, Amazonas Region, in the northern Peruvian Andes, where it occurs at an altitude of 2,050 m asl.

Population [top]

Population:The population is suspected to be decreasing due to ongoing decline in the quality and extent of its habitat. There have been no additional field observations of this species since the type series was collected in 1989 (Wiens 1993).
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It is a riparian, semi-aquatic, stream-breeding frog, and may be found under rocks in cloud forest streams. It has been observed in muddy roadside ditches at night. It reproduces 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): The major threats to this species are not understood. 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 (e.g., 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 may occur in the Alto Mayo Protected Forest.

Conservation Needed
Habitat protection is urgently needed to ensure the maintenance of suitable habitat for this species. 

Research Needed
Further surveys need to be undertaken to locate this species and 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.
