Geographic Occurrence

Natural Resident: Colombia, Panama


According to Myers, 1991, Am. Mus. Novit., 3010: 1-15, all previous identifications of this species were wrong, and the Ecuadorian population may represent a distinct species. See account by Coloma, 1995, Misc. Publ. Mus. Nat. Hist. Univ. Kansas, 87: 25. Myers and Grant, 2009, Am. Mus. Novit., 3659: 1-12, assigned populations from northwestern Ecuador to the new Anomaloglossus confusus (Aromobatidae) and restricted the range of the species to the type locality (Chocó) and one locality in Antioquia, both in Colombia, thereby rendering all other populations assigned to this species without identifications. The Panama--Colombia range statement is retained until this is sorted out (DRF).
