Brame, 1968, J. Herpetol., 2: 1–64, who revised the genus, recognized two species groups, the Oedipina parvipes group and the Oedipina uniformis group; these were subsequently recognized as the subgenera Oedopinola and Oedipina, respectively, by García-París and Wake, 2000, Copeia, 2000: 42–70. See Good and Wake, 1997, Rev. Biol. Tropical, 45: 1185–1208, for discussion of relationships within the genus and a partial revision. Savage, 2002, Amph. Rept. Costa Rica: 145–157, provided a key and accounts for the species of Costa Rica. McCranie, Vieites, and Wake, 2008, Zootaxa, 1930: 1–17, suggested that Oedipina is the sister taxon of Nototriton and that Oeditriton (subgenus of Oedipina) is the sister taxon of the subgenera Oedipina and Oediopinola. McCranie and Townsend, 2011, Zootaxa, 2990: 59–68, presented a tree of the species. In the tribe Bolitoglossini of Vieites, Nieto-Roman, Wake, and Wake, 2011, Mol. Phylogenet. Evol., 59: 633. Köhler, 2011, Amph. Cent. Am.: 82–90, provided a brief summary of natural history, a key to the species of Central America, and range maps and photographs of the species. Raffaëlli, 2013, Urodeles du Monde, 2nd ed.: 371–385, provided brief accounts, photographs, and range maps for the species. Ovalle-Pacheco, Camacho-Rozo, and Arroyo, 2019, Check List, 15: 400, reported an apparently unnamed species in the state of Boyacá, Colombia, associated with the Magdalena Valley, 1000 to 1100 m elevation. Raffaëlli, 2022, Salamanders & Newts of the World: 846–875, provided species accounts summarizing systematics, life history, population status, and distribution (including a polygon map).
