This species is known only from two sites in San Martin Department 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).
This species has a very restricted geographic range, but 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.
It is not present in any protected areas. Further research is needed, for example regarding the limits of its range, and concerning its ecology and population status.
