Comment

See account by Heyer, Rand, Cruz, Peixoto, and Nelson, 1990, Arq. Zool., São Paulo, 31: 317-318. Izecksohn and Carvalho-e-Silva, 2001, Anf. Municipio Rio de Janeiro: 87, provided a brief account and photo. Canelas and Bertoluci, 2007, Iheringia, Zool., 97: 21-26, provided a record for the Serra do Caraça, southern end of the Serra do Espinhaço, Minas Gerais, Brazil. Brusquetti and Lavilla, 2006, Cuad. Herpetol., 20: 23, suggested that Paraguayan records of this species are based on misidentified Proceratophrys avelinoi. See account (as Ceratophrys fryi) by Cochran, 1955 "1954", Bull. U.S. Natl. Mus., 206: 230-232. See discussion in revision by Prado and Pombal, 2008, Arq. Zool., São Paulo, 39: 1-85. Carnaval and Bates, 2007, Evolution, 61: 2942-2957, discussed molecular phylogeography. Amaro, Rodrigues, Yonenaga-Yassuda, and Carnaval, 2012, Mol. Phylogenet. Evol., 62: 880–888, also discussed molecular phylogeography, suggested that two morphologically indistinguishable lineages can be detected via molecular markers. Dias, Carvalho-e-Silva, and Carvalho-e-Silva, 2013, Zootaxa, 3683: 427–438, reported on the morphology of the larval chondrocranium. Rodriguez, Börner, Pabijan, Gehara, Haddad, and Vences, 2015, Evol. Ecol., 29: 765–785 (and supplemental data), reported on phylogeographic diversity and its causes. Eterovick, Souza, and Sazima, 2020, Anf. Serra do Cipó: 1–292, provided an account, life history information, and an identification scheme for the Serra de Cipó, Minas Gerais, Brazil. Pezzuti, Leite, Rossa-Feres, and Garcia, 2021, S. Am. J. Herpetol., 22 (Special Issue): 1–109, described and discussed larval morphology and natural history. Santos, Feio, and Nomura, 2023, Biota Neotrop., 23 (3:e20231486): 1–43, characterized tadpole morphology as part of an identification key to the tadpoles of the Brazilian Cerrado.
