Removed from the synonymy of Osteocephalus taurinus by Duellman and Mendelson, 1995, Univ. Kansas Sci. Bull., 55: 344, where it had been placed by Trueb and Duellman, 1971, Occas. Pap. Mus. Nat. Hist. Univ. Kansas, 1: 31. Lynch, 2008, Rev. Acad. Colomb. Cienc. Exact. Fis. Nat., 32: 87-91, provided the Colombia records and discussed biogeography. Jungfer, 2010, Zootaxa, 2407: 46, suggested that Brazilian specimens may be Osteocephalus vilarsi. In the Osteocephalus planiceps species group of Jungfer, Faivovich, Padial, Castroviejo-Fisher, Lyra, Berneck, Iglesias, Kok, MacCulloch, Rodrigues, Verdade, Torres-Gastello, Chaparro, Valdujo, Reichle, Moravec, Gvoždík, Gagliardi-Urrutia, Ernst, De la Riva, Means, Lima, Señaris, Wheeler, and Haddad, 2013, Zool. Scripta, 42: 351-380. See range map in Ferrão, Moravec, Moraes, Carvalho, and Gordo, 2019, PeerJ, 7(e8160): 4, who suggested that the records for Jaú National Park on the lower Negro River actually represent Osteocephalus vilarsi. Included in the Brazilian fauna by Segalla, Berneck, Canedo, Caramaschi, Cruz, Garcia, Grant, Haddad, Lourenço, Mângia, Mott, Nascimento, Toledo, Werneck, and Langone, 2021, Herpetol. Brasil., 10: 166, but DRF is unaware of any published localities for Brazil.
