Peters, 1973, Smithson. Contrib. Zool., 145: 1–49, reviewed the species of Ecuador and defined species groups. The species groups noted in the species accounts were defined by Lynch, 1993, Alytes, 11: 77–87, of which the Atelopus ignescens group is united solely by plesiomorphy. In the same paper, Lynch discussed the evidence of phylogeny among the "atelopodid" genera (Osornophryne, Frostius, and Atelopus). La Marca, García-Pérez, and Renjifo, 1990 "1989", Caldasia, 16: 97–104, supplied a key to the species of Venezuela. Graybeal and Cannatella, 1995, Herpetologica, 51: 121, suggested evidence supporting the monophyly of this taxon. Frost, Grant, Faivovich, Bain, Haas, Haddad, de Sá, Channing, Wilkinson, Donnellan, Raxworthy, Campbell, Blotto, Moler, Drewes, Nussbaum, Lynch, Green, and Wheeler, 2006, Bull. Am. Mus. Nat. Hist., 297: 129, suggested that Atelopus is the sister taxon of Osornophryne (among the exemplars studied) and that Atelopus + Osornophryne is the sister taxon of remaining bufonids, with the exception of Melanophryniscus and likely Truebella. Van Bocxlaer, Loader, Roelants, Biju, Menegon, and Bossuyt, 2010, Science, 327: 679–682, suggested that Atelopus is in a basal polytomy with Oreophrynella and a clade subtending all other bufonids excluding Melanophryniscus. See Lötters, 1996, Neotrop. Toad Genus Atelopus1-143, for recent summary of taxonomy and distribution. Savage, 2002, Amph. Rept. Costa Rica: 186–191, provide accounts and keys to the species of Costa Rica. Portik and Papenfuss, 2015, BMC Evol. Biol., 15 (152): 1–19, recovered Atelopus as the sister of Osornophryne and together the sister taxon of all bufonids excluding Melanophryniscus and Dendrophryniscus. Barrio-Amorós, 1999 "1998", Acta Biol. Venezuelica, 18: 5–7, reported on literature and distribution for the species in Venezuela. Rueda-Almonacid, Rodríguez-Mahecha, Lötters, La Marca, Kahn, and Angulo, 2005, Ranas Arlequines, provide brief accounts for all species and reported 20 unnamed species from Peru, Ecuador, Colombia, and Venezuela. Guayasamin, Bonaccorso, Duellman, and Coloma, 2010, Zootaxa, 2574: 55–68, reported on the molecular phylogenetics of the Atelopus ignescens and Atelopus bomolochos species complexes in the northern Andes. Lötters, van der Meijden, Coloma, Boistel, Cloetens, Ernst, Lehr, and Veith, 2011, Syst. Biodiversity, 9: 45–57, provided a molecular analysis that suggested that Osornophryne is not within Atelopus and that the former Atelopus ignescens and Atelopus longirostris groups are not historical units. Pyron and Wiens, 2011, Mol. Phylogenet. Evol., 61: 543–583, in their study of Genbank sequences, suggested the monophyly of this taxon (although not addressing Oreophrynella), its placement as the sister taxon of all bufonids with the exception of Melanophryniscus, and provided a tree of exemplar species. Mueses-Cisneros and Moreno-Quintero, 2012, Herpetotropicos, Mérida, 7: 39–54, noted an unnamed species in Nariño, southwestern Colombia. Köhler, 2011, Amph. Cent. Am.: 98–102, provided a brief summary of natural history, an identification key to the species of Central America and range maps and photographs of the species.
