From the IUCN Red List Species Account:

 

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).

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.

Population

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).

Population Trend

unknown

Major Threats

There is no information on threats to this species.

Conservation Actions

Conservation Actions
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. 

Research Needed
Further research is needed into its distribution, population status and trends, and ecology.

Red List Status

Least Concern (LC)

Rationale

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.
