Geographic Occurrence

Natural Resident: Brazil

Endemic: Brazil


In the Physalaemus olfersii group of Nascimento, Caramaschi, and Cruz, 2005, Arq. Mus. Nac., Rio de Janeiro, 63: 311. See account (including description of advertisement call) by Heyer, Rand, Cruz, Peixoto, and Nelson, 1990, Arq. Zool., São Paulo, 31: 316–317. Cruz, Cassini, and Caramaschi, 2008, S. Am. J. Herpetol., 3: 242, suggested that the taxon is a species complex. Giaretta, Martins, and Santos, 2009, Zootaxa, 2266: 51–60, compared the calls of Physalaemus olfersi, Physalaemus moreirae, Physalaemus bokermanni, and Physalaemus jordanensis, and described the tadpole. Species redelimited and discussed by Cassini, Cruz, and Caramaschi, 2010, Zootaxa, 2491: 1–33. In the Physalaemus cuvieri clade, Physalaemus olfersii species group, of Lourenço, Targueta, Baldo, Nascimento, Garcia, Andrade, Haddad, and Recco-Pimentel, 2015, Mol. Phylogenet. Evol., 92: 204–216. Carvalho, Haddad, and Gridi-Papp, 2019, Acta Herpetol., Firenze, 14: 21–26, reported on tonal calls. Hepp and Pombal, 2020, Zootaxa, 4725: 1–106, discussed this species as part of a genus-wide discussion of bioacoustical traits among the species.
