This species is only known from two sites in San Martín Region on the eastern slopes of the central Andes in northern Peru (Duellman 2004). Both localities, Abra Pardo Miguel (2,050 m asl) and Venceremos (1,620 m asl), lie along the road from Balzapata to Rioja, in the northern Cordillera Central. It probably occurs more widely over the Andean foothills of Peru.
Habitat and Ecology
This is a diurnal species that was collected in tropical montane forest, where it was associated with streams (Duellman 2004). Its breeding habits are not known, but the larvae probably develop in streams.
Its population status is not known, as this frog is only known from two specimens (Duellman 2004).
There is no information on major threats. The fungal disease chytridiomycosis was first reported from Peru in 1998 (Lips et al. 2008), and has been responsible for severe declines and extinctions among Andean amphibians, especially of high-elevation, stream-breeding frogs with small ranges (Whittaker and Vrendenberg 2010). It is however unknown whether this disease represents a specific threat to this species.
This species is not present in any protected areas.
Further research is needed regarding the limits of its range, and concerning its population status, ecology, and threats.
Red List Status
Data Deficient (DD)
Listed as Data Deficient in view of continuing uncertainties as to its extent of occurrence, population status, ecological requirements and threats.
