See account by Jungfer, 2010, Zootaxa, 2407: 39-41, who removed Hyla mimetica from the synonymy of Dendropsophus triangulum, where it had been placed by Duellman, 1974, Occas. Pap. Mus. Nat. Hist. Univ. Kansas, 27: 19. 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. See brief account for the Manu region, Peru, by Villacampa-Ortega, Serrano-Rojas, and Whitworth, 2017, Amph. Manu Learning Cent.: 178–179. Venegas, García Ayachi, Toral, Malqui, and Ron, 2023, Evol. Syst., 7: 237–251, provided molecular evidence that this nominal species is a complex, with the Cusco region harboring an unnamed lineage which is the sister taxon of Osteocephalus mimeticus sensu stricto + Osteocephalus vasquezi
