Class: Amphibia > Order: Anura > Family: Hylidae > Subfamily: Cophomantinae > Genus: Boana > Species: Boana cinerascens

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.

Publ., 22: 28, provided a brief account for the Iquitos region of northeastern Peru as Hyla granosaDe la Riva, Márquez, and Bosch, 1997, Bonn. Zool. Beitr., 47: 175–185, reported on the call, as Hyla granosaLescure and Marty, 2000, Collect. 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. Fouquet, Gilles, Vences, Marty, Blanc, and Gemmell, 2007, PLoS One, 10 (e1109): 1–10, provided molecular evidence that this is a species complex (as Hypsiboas granosa). 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. See Barrio-Amorós, Rojas-Runjaic, and Señaris, 2019, Amph. Rept. Conserv., 13 (1: e180): 63, for comments on range, taxonomy (noting via personal communications from D. Pareja and P. Kok that this name covers a complex of species), and literature. For identification of larvae (as Hyla granosa) in central Amazonia, Brazil, see Hero, 1990, Amazoniana, 11: 201–262. Sturaro, Costa, Maciel, Lima, Rojas-Runjaic, Mejia, Ron, and Peloso, 2020, Zootaxa, 4750: 1–30, discussed the complex nature of this complex, resurrecting the species name Boana gracilisAlves da Silva, Carvalho, Pereira Silva, Fadel, Dantas, Brandão, and Santana, 2020, Biota Neotrop., 20 (1: e20190838): 16, reported the species from the state of Tocantins, Brazil. Señaris and Rojas-Runjaic, 2020, in Rull and Carnaval (eds.), Neotrop. Divers. Patterns Process.: 571–632, commented on range and conservation status in the Venezuelan Guayana.
