Hyla cinerascens Spix, 1824, Animal. Nova Spec. Nov. Test. Ran. Brasil.: 35. Type(s): Not specifically designated, but including animal figured in pl. 8, fig. 4 in the original publication; syntypes were ZSM 2498/0 (2 specimens), destroyed, according to Duellman, 1977, Das Tierreich, 95: 26; Hoogmoed and Gruber, 1983, Spixiana, München, Suppl., 9: 366 (although only one specimen implied in original publication); and confirmed by Glaw and Franzen, 2006, Spixiana, München, 29: 166. MPEG 40282 designated neotype by Sturaro, Costa, Maciel, Lima, Rojas-Runjaic, Mejia, Ron, and Peloso, 2020, Zootaxa, 4750: 6. Type locality: "Ecgá prope flumen Teffe" (= Ega, Tefé), Amazonas, Brazil. Neotype from "Tefé (03°16’47”S and 64°45’09”W), Amazonas, Brazil". Synonymy with Hyla albomarginata by Peters, 1872, Monatsber. Preuss. Akad. Wiss. Berlin, 1872: 226; Nieden, 1923, Das Tierreich, 46: 260. Placed in the synonymy of Hyla granosa by Hoogmoed and Gruber, 1983, Spixiana, München, Suppl., 9: 366, who suggested that an application to the International Commission for Zoological Nomenclature would be necessary to retain the priority of Hyla granosa.
