Comment

See account by Jungfer, 2010, Zootaxa, 2407: 41-44, who removed this species from the synonymy of Osteocephalus taurinus, where it had been placed by Bokermann, 1966, Lista Anot. Local. Tipo Anf. Brasil.: 64. Tentatively included in the Osteocephalus taurinus 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. Rediscovered after 75 years by Ferrão, Moravec, Moraes, Carvalho, and Gordo, 2019, PeerJ, 7(e8160): 1–35, who detailed the morphology and color variationi and expanded the known rang, and on the basis of molecular data transferred it to the Osteocephalus planiceps group.
