This species is known from the vicinity of the type locality: Cordillera Azul, Pass of Carretera Central, in Huánuco Region, Peru. It occurs at 1,650 m asl.
Habitat and Ecology
Its habitat is cloud forest, where the trees are generally spaced widely, separated by 2–3 m, in tall shrubland. Wet depressions and small ravines are scattered throughout the area, with slightly taller (4-9 m high) elfin forest. This species breeds by direct development.
Its population status is unknown. The holotype is in poor condition and therefore the validity of this species is uncertain (E. Lehr pers. comm. December 2017).
There is no information about the threats to this species.
It might occur in Parque Nacional Cordillera Azul, but this requires confirmation.
Further taxonomic research is needed to determine the validity of this species (E. Lehr pers. comm. December 2017). More information is needed on this species' distribution, population status, and ecology.
Red List Status
Data Deficient (DD)
Listed as Data Deficient in view of continuing uncertainties as to its taxonomic validity, extent of occurrence, status and ecological requirements.
Eleutherodactylus nebulosus Henle, 1992 was discovered to be a junior homonym of Syrrhophus nebulosus Taylor, 1943, hence Eleutherodactylus caliginosus Lynch, 1996 was published as a replacement name. The species is now treated under the genus Pristimantis, so its original specific name of nebulosus has been restored. Duellman and Lehr (2009) suggested that because the holotype is in poor condition that association with a living population is problematic.
