Natural Resident: Colombia, Ecuador


As used by Lynch and Duellman, 1973, Occas. Pap. Mus. Nat. Hist. Univ. Kansas, 16: 1-66, this name applies to the species currently recognized as Centrolenella lynchi; see Duellman, 1980, Trans. Kansas Acad. Sci., 83: 26-32. In the Centrolene prosoblepon 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. Hutter, Escobar-Lasso, Rojas-Morales, Gutiérrez-Cárdenas, Imba, and Guayasamin, 2013, J. Nat. Hist., London, 47: 3011–3032, reported on vocalization. Arteaga-Navarro, Bustamante, and Guayasamin, 2013, Amph. Rept. Mindo: 49–50, provided an account and dot map for Ecuador. See account, photograph, and dot map by Vanegas-Guerrero, Ramírez-Castaño, and Guevara-Molina, 2014, Catal. Anf. Rept. Colombia, Medellín, 2(2): 51–55. Guayasamin, Cisneros-Heredia, McDiarmid, Peña, and Hutter, 2020, Diversity, 12 (222): 166–171, provided a detailed account, including natural history, primarily focused on the Ecuador segment of the range, and who noted that (1) the population from Reserva Buenaventura, El Oro Province, Ecuador, is likely an unnamed species and (2) in at least some literature Nymphargus grandisonae was confused with Nymphargus lynchi. See Freile, Coloma, Terán-Valdez, Acosta-López, Tapia, and Pazmiño-Otamendi, 2020, Anfibios de Junín: 30–31, for brief account for Junín, Ecuador (identification, call, tadpole morphology, habitat, range) and photograph. Díaz-Ricaurte and Guevara-Molina, 2022, Stud. Neotrop. Fauna Environ., 57: 51–65, provided a record from Pensilvana municipality, Caldas Province, Colombia.
