Listed as Least Concern in view of its wide distribution, presumed large population, and given that it occurs in a region where there are still large tracts of suitable habitat remaining.
|Previously published Red List assessments:|
|Range Description:||This species occurs in the western Amazon basin and on the lower Amazonian slopes of the Andes at 100–800 m asl. It has been recorded from Ecuador (Napo and Pastaza provinces) and eastern Peru (Regions of Amazonas, Loreto and Madre de Dios). It possibly occurs in the Putumayo and Amazonas departments of Colombia (Lynch 1999, Acosta-Galvis 2000) and it is suspected to occur in Bolivia (De la Riva et al. 2000).|

Very little population information is currently available for this species, probably because of its cryptic lifestyle. In 2006, two individuals were found during 90 person/day surveys in the Region of San Martín, Peru (von May et al. 2008). Individuals have been observed as recently as 2015 (Padial et al. 2016).
|Current Population Trend:||Unknown|
|Habitat and Ecology:||It is a subterranean species of primary tropical rainforest. At Lago Agrio, Ecuador, individuals were found during clearance of primary forest by bulldozers (Duellman 1978). It is not known whether it can adapt to modified habitats. Its breeding habits are unknown.|
|Movement patterns:||Not a Migrant|
|Use and Trade:||
There are no records of this species being utilized.
|Major Threat(s):||There is no information on threats to this species.|
In Ecuador, this species has been recorded from Yasuní National Park, and it possibly also occurs in Limoncocha Biological Reserve. It occurs in Manu National Park, Purús Communal Reserve and might occur in the Allpahuayo Mishana National Reserve, although this needs confirmation.
Further research is needed into its distribution, population status and trends, and ecology.
