This species is known from only a single threat-defined locality in Quebrada Amincha near Ollagüe, in El Loa Province, Chile, from 3,800-3,900 m asl. It has an area of occupancy and extent of occurrence of 9 km2.
Habitat and Ecology
This is an aquatic frog, occurring in streams in the high Andes, and which is not known to occur in modified or degraded habitats. Breeding takes place in streams.
The species was originally known from two sub-populations in Quebrada Amincha and del Inca, which were separated by 1 km from each other. However the population has undergone a decline of 50% over the past 10 years, as the sub-population in Quebrada del Inca disappeared after the stream was canalized for agricultural activities. The sub-population in Quebrada Amincha is small, and part of the stream has been canalized in 2013 (A. Charrier pers. comm. 2015).
Abstraction of surface water for domestic and agricultural use is a threat because it would affect habitat quality and quantity.
It does not occur in any protected area.
Red List Status
Critically Endangered (CR)
Listed as Critically Endangered because it has disappeared from one of the two originally known locations due to canalization of the stream in which it lived, and the remaining population is now restricted to an area of less than 10 km2. Habitat quantity and quality are affected by abstraction of surface water in this remaining location. It is estimated that the population has suffered a reduction of at least 50% over the past 10 years due to the disappearance of one of the sub-populations.
