This species is known from two localities in southeastern Ecuador
(provinces of Morona-Santiago and Zamora-Chinchipe) and two in
northeastern Peru (region of Cajamarca). It is found between 1,100-1,500 m asl (Cisneros-Heredia et al. 2008). It is possible that it may occur more widely (D. Cisneros-Heredia pers. comm. September 2009).
Habitat and Ecology
This species is found in thorn and evergreen forests. Active at night, frogs of this species can be found on rocks on the borders and in the spray zone of waterfalls (Cisneros-Heredia et al. 2008). It is thought that this species depends on well-preserved, unpolluted rivers, and that changes in hydrological patterns would likely affect its survival (D. Cisneros-Heredia pers. comm September 2009). It is presumed to breed in streams.
This is considered to be a rare species (D. Cisneros-Heredia pers. comm. September 2009).
Its habitat is threatened with destruction due to agricultural expansion, urban development, mining and water retention projects which would modify the hydrological cycles of the Cordillera Oriental (D. Cisneros-Heredia pers. comm. September 2009).
It can be found in both private and public protected areas. Additional conservation actions for this species include watershed management and protection (D. Cisneros-Heredia pers. comm. September 2009).
Red List Status
Data Deficient (DD)
Listed as Data Deficient since it has only recently been
described, and there is still very little information on its extent of occurrence,
status and ecological requirements.
