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. Type locality: "Ecgá prope flumen Teffe" (= Ega, Tefé), 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.

Patrimoines Nat., Paris, 45: 132-133, provided a brief account and photo. In the Hypsiboas punctatus group of Faivovich, Haddad, Garcia, Frost, Campbell, and Wheeler, 2005, Bull. Am. Mus. Nat. Hist., 294: 88. Kok and Kalamandeen, 2008, Intr. Taxon. Amph. Kaieteur Natl. Park: 168-169, provided an account and noted an unnamed species in Guyana that has been confused with this species. See account for Surinam population by Ouboter and Jairam, 2012, Amph. Suriname: 136-139. See Cole, Townsend, Reynolds, MacCulloch, and Lathrop, 2013, Proc. Biol. Soc. Washington, 125: 403-404, for brief account and records for Guyana. Batallas-R. and Brito, 2016, Rev. Mexicana Biodiversidad, 87: 1292–1300, reported on vocalizations from Sangay National Park, southeastern Ecuador.  Motta, Menin, Almeida, and Hrbek, 2018, Zootaxa, 4438: 79–104, on the basis of 16S rRNA sequence divergence suggested that this nominal species is composed of at least two lineages, one in central Amazonia and the other in the Guianas.
