Comment

Removed from the synonymy of Scinax catharinae, without comment, by Carvalho-e-Silva and Peixoto, 1991, Rev. Brasil. Biol., 51: 268. These authors also associated this species with the Scinax x-signatus group. Treated as a synonym of Scinax ruber by Duellman, 1977, Das Tierreich, 95: ix, 97, and Duellman and Wiens, 1993, Occas. Pap. Mus. Nat. Hist. Univ. Kansas, 153: 37–38. Pombal, Haddad, and Kasahara, 1995, J. Herpetol., 29: 5, and Pombal, Bastos, and Haddad, 1995, Naturalia, São Paulo, 20: 213–225, reported on the advertisement call and noted that there may be several species covered by the name Scinax alter and assigned it to the Scinax ruber group. Alves and Carvalho-e-Silva, 2002, J. Herpetol., 36: 133–137, documented differences in the tadpoles of Scinax alter and Scinax cuspidatus. 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. Izecksohn and Carvalho-e-Silva, 2001, Anf. Municipio Rio de Janeiro: 56, provided a brief account and photo. Nunes, Kwet, and Pombal, 2012, Copeia, 2012: 554–569, revised and redelimited the species, as well as discussing the advertisement call and larval morphology. In the Scinax auratus 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. Am. J. Herpetol., 27 (Special Issue): 84 (see comment under Hylinae).
