Geographic Occurrence

Natural Resident: Colombia, Ecuador


In the Cochranella ocellata group according to Ruiz-Carranza and Lynch, 1991, Lozania, 57: 1–30. Cisneros-Heredia and McDiarmid, 2007, Zootaxa, 1572: 52, discussed the species in Ecuador and provided access to the relevant literature, and noted that this is probably a complex of species. Cisneros-Heredia and Yánez-Muñoz, 2007, S. Am. J. Herpetol., 2: 3, considered this species to be in (their nomenclature) the Cochranella griffithsi clade, along with Nymphargus buenaventura, Nymphargus cariticommata, and Nymphargus wileyi. See photograph, map, description of geographic range and habitat, and conservation status (as Cochranella griffithsi) in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 214. Arteaga-Navarro, Bustamante, and Guayasamin, 2013, Amph. Rept. Mindo: 51–53, provided an account and dot map for Ecuador. Guayasamin, Cisneros-Heredia, McDiarmid, Peña, and Hutter, 2020, Diversity, 12 (222): 171–175, provided a detailed account, including natural history, adult morphology, and advertisement call, primarily focused on the Ecuador segment of the range, and who explicitly excluded the Colombian populations as belonging to this species without resolving their status; this population (other than the La Planada, Nariño, record) now being assigned to Nymphargus pijao).
