This species is known only from the vicinity of the type locality of Cordillera de Carpish at San Marcos, Umari District, Pachitea Province, Huánuco Region, Peru. It occurs at elevations between 3,100–3,190 m asl (Lehr and Oróz 2012).
Habitat and Ecology
This species inhabits primary humid montane forest. All individuals have been found during day in the leaf litter and under tree trunks (Lehr and Oróz 2012). It is presumed that this species has a cryptic mode of life restricted to the leaf litter and moss, and reproduces by direct development similar to other members of the genus.
There is little information available on the population status and trends for this species. It is known only from the three specimens collected in 2010, which constitute the type series (Lehr and Oróz 2012).
In 2010, the type locality showed some evidence of human activities, such as logging for firewood and construction of agricultural parcels (Lehr and Oróz 2012).
It occurs in a small protected area, San Marcos Private Conservation Area.
More information is needed on this species' distribution, population status, natural history, and threats.
Red List Status
Data Deficient (DD)
Listed as Data Deficient because this species was only recently described and there are continuing uncertainties as to its extent of occurrence (EOO), population status and ecological requirements. However, it is important to note that the type locality may be threatened by agriculture, so this species should be closely monitored.
