Listed as Critically Endangered, Possibly Extinct, because the species is only known from its holotype, which was collected in 1976. The species has not been observed since, in spite of attempts to find it. The original description mentioned that it may also occur in Zapahuira, but the area has been dried out by humans and the species has not been found there.
|Date last seen:||1976|
|Previously published Red List assessments:|
|Range Description:||This species is known only from the type locality: Murmuntani, Parinacota Province, in extreme northern Chile at 3,200 m asl, on the western slopes of the Andes. It has an area of occupancy of 100 km2 and an extent of occurrence of 100 km2.|

|Population:||The species was described in 1976, but nobody has ever been able to identify another individual after the original description.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||The type locality is a small high-altitude stream, close to human villages. It is wholly aquatic, requiring small permanent streams to persist, and its tolerance to habitat destruction is unknown. Reproduction occurs in the water and it has large, free-swimming tadpoles.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Movement patterns:||Not a Migrant|
|Use and Trade:||There are no records of this species being utilized.|
|Major Threat(s):||The main threat to the species is water extraction from streams, because local people extract water for cattle ranching and human use; it might also be affected by the impact of cattle on the streams. The species is only known from its holotype; it has not been collected ever since in spite of several attempts to find it. The description of the holotype mentioned that the species also occurs in Zapahuira, but this area has dried out and the frog has not been found there.|
It does not occur in any protected area.
Habitat protection and maintenance is recommended, complemented by more general actions to mitigate the effects of water pollution and channelization.
Close monitoring of potential surviving sub-populations of this species is required.
