From the IUCN Red List Species Account:


Range Description

This species is known only from the type locality, 15 km southeast of Maraypata near Laguna Gwengway, and from Alcas, San Rafael District, Ambo Province, Hu├ínuco Region, Peru. It occurs between 3,480 and 3,680 m asl. Its estimated extent of occurrence (EOO) is 157 km2 and all individuals are considered to occur at two threat-defined locations. It is expected to have a restricted distribution as known for the genus (E. Lehr pers. comm. April 2017).

Habitat and Ecology

This species inhabits Andean grassland (puna) habitats and transitional areas between puna and montane forest. It has also be found in disturbed grassland areas including gardens and potato fields, however it is unknown whether the species is able to persist in these modified habitats in the long term (E. Lehr pers. comm. December 2017). It is presumed to breed by direct development.


It is an uncommon species. In 2001, 15 individuals were observed over two person-days, while two individuals were detected over two person-days during similar surveys in 2003 (von May et al. 2008). The current population trend is unknown as surveys have not been conducted since 2003.

Population Trend


Major Threats

The major threat to this species in the past was loss of forest habitat in the transitional zone. In 2003, there were no apparent threats present at the type locality, however there is little understanding of current threats to this species. Agrochemical pollution might pose a threat, and there is likely ongoing habitat decline due to agriculture and human settlement throughout the range of this species (E. Lehr pers. comm. April 2017).

Conservation Actions

Conservation Actions
It does not exist in any protected areas. 

Conservation Needed
This species would likely benefit from improved habitat protection at sites where it is known to occur.

Research Needed
More information is needed on this species' distribution, population status, ecology, and threats. Future surveys to determine whether the species is able to persist in modified habitats (E. Lehr pers. comm. December 2017).

Red List Status

Vulnerable (VU)


Listed as Endangered because of its extent of occurrence (EOO) of 157 km2, it occurs in two threat-defined locations, and there is a continuing decline in the extent and quality of its habitat.
