Comment

In the Scinax ruber group of Pombal, Haddad, and Kasahara, 1995, J. Herpetol., 29: 1–6. The Scinax ruber group rejected as nonmonophyletic by Faivovich, 2002, Cladistics, 18: 367–393. In the Scinax ruber clade, unassigned to group, of Faivovich, Haddad, Garcia, Frost, Campbell, and Wheeler, 2005, Bull. Am. Mus. Nat. Hist., 294: 97. Duellman, 1978, Misc. Publ. Mus. Nat. Hist. Univ. Kansas, 65: 139–140, provided a brief account including characterization of call and tadpole. See account by Duellman and Wiens, 1993, Occas. Pap. Mus. Nat. Hist. Univ. Kansas, 153: 9–12 Rodríguez and Duellman, 1994, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 22: 48, provided a brief account for the Iquitos region of northeastern Peru. Lescure and Marty, 2000, Collect. Patrimoines Nat., Paris, 45: 172–173, provided a photo and brief account for French Guiana. Malambo-L. and Madrid-Ordóñez, 2008, Rev. Acad. Colomb. Cienc. Exact. Fis. Nat., 32: 285–289, provided a record for Municipio de Florencia, Cauquetá, Colombia, and briefly outlined the range in Colombia. França and Venâncio, 2010, Biotemas, 23: 71–84, provided a record for the municipality of Boca do Acre, Amazonas, with a brief discussion of the range. Bernarde, Machado, and Turci, 2011, Biota Neotrop., 11: 117–144, reported specimens from Reserva Extrativista Riozinho da Liberdade, Acre, Brazil. Carvalho, Teixeira, Duellman, and Giaretta, 2015, Phyllomedusa, 14: 139–146, reported on the range (map. on p. 144) and redescribed the advertisment call, and doubted the French Guiana record. For identification of larvae (as Hyla cruentomma) in central Amazonia, Brazil, see Hero, 1990, Amazoniana, 11: 201–262. 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. Taucce, Costa-Campos, Carvalho, and Michalski, 2022, Eur. J. Taxon., 836: 114, discussed the evidence for the presence of this or a closely related but unnamed species in French Guiana and Amapá, Brazil. Schiesari, Rossa-Feres, Menin, and Hödl, 2022, Zootaxa, 5223: 70–32, detailed larval morphology and natural history. In the Scinax cruentomma group of Araujo-Vieira, Lourenço, Lacerda, Lyra, Blotto, Ron, Baldo, Pereyra, Suárez-Mayorga, Baêta, Ferreira, Barrio-Amorós, Borteiro, Brandão, Brasileiro, Donnelly, Dubeux, Köhler, Kolenc, Leite, Maciel, Nunes, Orrico, Peloso, Pezzuti, Reichle, Rojas-Runjaic, Silva, Sturaro, Langone, Garcia, Rodrigues, Frost, Wheeler, Grant, Pombal, Haddad, and Faivovich, 2023, S.
