This species has been recorded from several scattered localities in the Pacific inter-Andean valleys of Ancash, Huánuco, Amazonas, and Piura Regions, Peru, however its true distribution is not well understood (E. Lehr and C. Aguilar pers. comm. December 2017). The original subpopulation from which this species was described was apparently introduced to Lima from its original range, although this subpopulation may now be extinct. Its altitudinal range within its native distribution is 665–2,180 m asl.
Habitat and Ecology
This species is present in arid areas including coastal 'desert' and dry shrublands. Generally occurs close to streams with dense vegetation; breeding takes place in quiet waters close to streams. The species is not greatly sensitive to habitat change.
It is considered a common species, as many frogs have been heard calling, however the species is difficult to find (E. Lehr pers. comm. December 2017). Its current population trend is not known.
Threats to this species are unknown. There is some agriculture within its range, however there is not information on whether it affects the species (E. Lehr pers. comm. December 2017).
It has been recorded from at least one protected area, Pantanos de Villa Reserved Zone in Lima.
More information is needed on this species' distribution, population status and trends of both native and introduced subpopulations. Taxonomic work is needed to determine if this form is a complex of more than one species (E. Lehr pers. comm. December 2017).
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its relatively wide distribution and presumed large population.
This species is likely to be a complex of several cryptic species (E. Lehr pers. comm. December 2017).
