Range Description

This species is known from two streams at altitudes of 500 and 730m asl on ridges extending from the Andes into the Amazonian Basin in San Martin Department, and from Río Pauya, Loreto Department, in northern Peru. It was relatively recently discovered and is likely to range much more widely.

Habitat and Ecology

All the adults were found on mossy boulders, and some juveniles were also discovered on herbaceous vegetation, at night in a deep ravine in lower humid montane forest. The type locality is a rocky gorge into which two streams plunge. The sides of the gorge are nearly vertical rock walls, and the floor of the gorge is littered with huge boulders, many of which support thin layers of moss. The second locality is a wooded, boulder-strewn with cacade stream on the road. This species breeds by direct development.


Its population status is unknown. Three adult males and two adult females were used to describe it.

Population Trend


Major Threats

Within its current known range it is threatened by loss of habitat through agricultural development (including the establishment of coffee plantations), selective wood extraction and human settlement. If this species is restricted to specific 'rocky gorge' type habitats, it might be particularly sensitive to habitat disturbance.

Conservation Actions

Its range overlaps with Parque Nacional Cordillera Azul.
