Comment
Previously confused with Osteocephalus leprieurii according to the original publication. Cisneros-Heredia, 2007, Herpetozoa, Wien, 19: 183, provided a record from 54 km east of the type locality. 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 Vasquez, Wheeler, and Haddad, 2013, Zool. Scripta, 42: 351-380. Forti, Foratto, Márquez, Pereira, and Toledo, 2018, PeerJ, 6(e4813): 1–19, characterized the advertisement call. Metcalf, Marsh, Torres Pacaya, Graham, and Gunnels, 2020, Herpetol. Notes, 13: 753–767, reported the species from the Santa Cruz Forest Reserve, Loreto, northeastern Peru. Gagliardi-Urrutia, García Dávila, Jaramillo-Martinez, Rojas-Padilla, Rios-Alva, Aguilar-Manihuari, Pérez-Peña, Castroviejo-Fisher, Simões, Estivals, Guillen Huaman, Castro Ruiz, Angulo Chávez, Mariac, Duponchelle, and Renno, 2022, Anf. Loreto: 114–115, provided a brief account, photograph, dot map, and genetic barcode for Loreto, Peru. Coloma and Duellman, 2025, Amph. Ecuador. Vol. 2: 471–474, provided an account, with photographs, which summarized identification, adult and larval morphology, systematics, natural history, distribution (including a dot map for Ecuador), conservation, and (on p. 591) the advertisement call.
