This species is known from two areas in Cuzco Department in southern Peru (Pistipata and Machu Pichu), and from a single locality in central La Paz, Bolivia. It has an altitudinal range of 1,820-2,000m asl. It presumably occurs more widely, particularly in localities between the two currently known sites.
Habitat and Ecology
This species is strongly associated with streams. At Pistipata, the vegetation consists of coffee and tea plantations with remnants of cloud forest. In Bolivia it has been collected in primary montane forest. Individuals call on rainy nights, on herbaceous plants on dripping wet cliffs and the upper sides of leaves over water, all adjacent to streams. Egg clutches are laid on the tips of the upper surfaces of the leaves, and the larvae develop in streams.
It is common in Peru, but uncommon in Bolivia.
It is unclear what the threats are to this species, which is possibly impacted by the loss and degradation of its habitats for human colonization and agricultural development, although in Peru it seems to survive well in coffee and tea plantations.
The potential impacts of localized climate change and possible infection with the chytrid fungus on this species require further investigation.
