|Reviewer/s:||Amori, G. (Small Nonvolant Mammal Red List Authority) & Schipper, J. (Global Mammal Assessment Team)|
This species is listed as Critically Endangered (Possibly Extinct) because it has not been seen despite extensive searches over the last 50 years, it is suspected to have undergone, or be undergoing, a population decline estimated to be more than 80% over ten years, the extent of occurrence is inferred to be less than 100 km², all individuals are in a single location, and there is continuing severe decline in the extent and quality of any remaining habitat.
|Range Description:||This species is known only from the Lomas de Atocongo, a group of low lying hills close to Lima in the west central Peru (Musser and Carleton, 2005). It was recorded between 600 to 800 m.|

|Population:||It has not been recorded since 1949 despite intense searches for the species. The population is believed to have significantly declined, and the species (if it is still extant) is considered to be still declining because of extensive habitat loss within its small range.|
|Habitat and Ecology:||It is known only from the distinct Coastal Lomas ecosystem (with desert or dryland habitat). It has not been recorded from modified habitats. It is terrestrial and probably nocturnal.|
|Major Threat(s):||The area that the species is known from has been heavily disturbed through pastoral (goats) grazing and mining activities. The very specific habitat that the species was recorded from is considered to be almost entirely converted.|
|Conservation Actions:||It has not been recorded from any protected areas. Further field studies are needed to try to determine whether this species still persists.|
