This species is currently known only from the type locality on the west slopes of Abra Tangarana (1,080m asl) north-east of the San Juan de Pacaysapa, Departamento San Martin, in northern Peru. It is likely to occur more widely, but is believed to have a restricted distribution.
Habitat and Ecology
The area in which this species occurs supports lower montane rainforest and cloud forest, whereas the intervening valleys are extensively cultivated. All individuals of this arboreal species were found on the upper surface of trees 1.5-2.0m above a small stream in a narrow ravine at night. Eggs are laid on leaves, and larvae develop in streams. This species needs the specific narrow microhabitat of flat damp areas with a constant source of water.
It is an uncommon species.
The main threats to the species are unclear, but habitat loss, as a result of the expansion of agricultural activities, wood extraction, and human settlement, is likely to be the main threat.
The species is not present in any protected areas, and some form of formal habitat protection is urgently needed along the west slopes of Abra Tangarana.
