Justification:
This species is listed as Least Concern since, although its extent of occurrence is probably less than 20,000 km², it occurs in an area of extensive, suitable habitat which appears not to be under significant threat, it has a presumed large population, and it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
History:
2004 Least Concern

Geographic Range [top]

Range Description: This species' geographic range is the northeastern slope of the Andes of Peru, within the Cordillera Central (Departments of Amazonas and San Martin).

Habitat and Ecology [top]

Habitat and Ecology: It is a diurnal, terrestrial species known from both humid and dry pre-montane and lowland forest (Duellman 2004). The species is associated with streams. Larvae are carried to streams by the female. It has been recorded from disturbed (partially cutover) rainforest (Duellman 2004), implying tolerance of some degree of habitat modification.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): Because of the large areas of suitable habitat available in protected areas to this species there are no major threats. Outside protected areas, there is some localized habitat loss through different human activities, principally agriculture.

Conservation Actions [top]

Conservation Actions: This species occurs within the Santiago Comaina Reserved Zone and the Alto Mayo protected area; no species-specific conservation measures are known. More information is needed on extent of occurrence, area of occupancy, population status, natural history and threats.
