Faivovich, Haddad, Garcia, Frost, Campbell, and Wheeler, 2005, Bull. Am. Mus. Nat. Hist., 294: 111, could not assign this species to any of the currently recognized taxa, but pending examination of the type left this species incertae sedis. Jungfer, 2010, Zootaxa, 2407: 36, subsequently discussed the species and transferred it to Osteocephalus. Tentatively included in the Osteocephalus buckleyi 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. Hoogmoed, 2013, Amphibia-Reptilia, 34: 421–432, provided new records, discussed the range, and rediagnosed the taxon. Maffei, Machado, Silva, Nascimento, and Hoogmoed, 2018, Phyllomedusa, 17: 145–152, discussed external morphological variation, natural history, and distribution. Ortiz, Moraes, Pavan, and Werneck, 2020, Vert. Zool., Senckenberg, 70: 357–366, confirmed the generic placement of this species.
