This species is known in Bolivia from Departamentos Cochabamba, La Paz and Santa Cruz. In Peru, it is known from several localities [Cosñipata (1,700m) (Departamento Cusco) and Tutumbaro (1,840m), (Departamento Ayacucho)] in cloud forest of the Cordillera Oriental. It has an altitudinal range of 300-2,000m asl.
Habitat and Ecology
An arboreal species associated with streams and edges of large rivers, from lowland to upland primary and slightly disturbed forest. The eggs are laid on leaves overhanging the streams; the larvae develop in streams. The site at Tutumbaro (Peru) is a disturbed cloud forest in a river valley with bamboo, ferns and elephants ear plant. Individuals have been recorded calling at night from upper sides of leaves of herbaceous plants and elephants ear plant within 1m of a slow stream. Several of the males were observed calling from the undersides of leaves 1-3m above stream at night.
It is common in Bolivia, uncommon in Peru.
There are no threats to the species in Bolivia; threats in Peru are not known. Good river quality is the main requirement for this species. The potential impacts of localized climate change and possible infection with the chytrid fungus for this species requires further investigation.
The range of this species is overlap with the Parque Nacional Manu. In Bolivia it is present in Pilon Lajas; Madidi; Cotapata and Amboro protected areas.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
