This species is known only from the Serrania de Sira, in the upper Amazon basin of eastern central Peru, at 2,400m asl.
Habitat and Ecology
It is restricted to an isolated, and mostly inaccessible, mountain ridge in the upper Amazon basin, where the habitat is generally montane and premontane tropical forest. This is a terrestrial species that is presumed to breed in streams, and which is probably intolerant of habitat modification.
There is very little information available on its population status, and only a few specimens have ever been seen. It appears to have last been recorded in 1988, and it is not known whether or not a population decline could have occurred since then. Due to the remoteness of the locality there have been no recent surveys for this species.
There is little human disturbance of this very isolated area, although both the pet trade and infection with chytridiomycosis are potential threats to this species in the future, and could lead to a rapid population decline. However, its distribution is so isolated that it might be safe from these threats.
It is found within the Reserva Comunal El Sira.
