This species is known only from the type locality in the upper reaches of the continuous mountain forests of Río Abiseo National Park, Mariscal Cáceres Province, San Martín Region, Peru (Rodríguez and Catenazzi 2017). It occurs from 2,890–3,110 m asl and its EOO is estimated to be 41 km2.
Habitat and Ecology
This species inhabits the leaf-litter of tropical moist montane forest. The reproductive stage of the holotype indicates that the species may reproduce in the dry season (Rodríguez and Catenazzi 2017). Although no eggs were found with the specimens, the large size of the well-developed eggs in the holotype strongly suggests direct development (Rodríguez and Catenazzi 2017).
It appears to have appear to have a healthy population within Río Abiseo National Park (Rodríguez and Catenazzi 2017).
There is currently no anthropogenic disturbance threatening the population within the Río Abiseo National Park (Rodríguez and Catenazzi 2017).
It has been found within Río Abiseo National Park.
More information is needed on this species' distribution, population status and natural history. Continuous population monitoring inside the park is recommended to provide stronger support for future assessments of the conservation status of this species (Rodríguez and Catenazzi 2017).
Red List Status
Least Concern (LC)
Listed as Least Concern since, although it has a restricted distribution—with an extent of occurrence (EOO) of ca 41 km2—it occurs in an area of extensive, suitable habitat which appears not to be under any significant threat and it has an apparent healthy population.
