This species is currently known from two streams at the type locality: "the ridge above base camp (near Chorro Blanco, about 4-4.5km directly north-east of Monte Seco, Río Zaña, Cajamarca Department, Peru, at 2,610m asl" (Cadle and McDiarmid 1990); and from about 2.5km north-east of Monte Seco at 1,800m asl along a trail to Chorro Blanco, also in Cajamarca Department, Peru.
Habitat and Ecology
This is a montane tropical forest species. Individuals were active mostly on vertical rock faces in the splash or spray zones of waterfalls on rock ledges (upper and lower surfaces) in or around waterfalls, and on liverwort and moss-covered wet boulders in midstream. Many individuals were on rock ledges in waterfalls 6-8m high. Breeding was observed only along permanent streams at high altitudes. Given that all individuals were associated with rock faces near or in waterfalls and that no egg masses were found attached to vegetation, Cadle and McDiarmid (1990) considered that eggs of this species are attached to rocks.
There is no information on its population status.
The major threats to this species are not known. There is regional destruction and loss of habitat for livestock and due to selective wood extraction. Protected areas in the region are also threatened by these impacts.
Further research is needed into this little-known species, including the potential impacts of localized climate change and potential infection with the chytrid fungus.
