Physalaemus spiniger (Miranda-Ribeiro, 1926)

Class: Amphibia > Order: Anura > Family: Leptodactylidae > Subfamily: Leiuperinae > Genus: Physalaemus > Species: Physalaemus spiniger

Engystomops spinigera Miranda-Ribeiro, 1926, Arq. Mus. Nac., Rio de Janeiro, 27: 155. Holotype: MZUSP 56, according to XXX. Type locality: "Iguape—S[ão]. Paulo", Brazil. The name was ascribed by Miranda-Ribeiro in the original publication to Boulenger, who provided the name via a jar label, but it was Miranda-Ribeiro who diagnosed the taxon and made the name available, thereby rendering Miranda-Ribeiro the author of the name (DRF; Article 50 of the ICZN [1999]) even though this was not his intention.

See account by Haddad and Pombal, 1998, J. Herpetol., 32: 557–565, who placed this species in the Physalaemus signifer group and noted its close resemblance to Physalaemus nanus, as well as describing the advertisement call and larval morphology. In the Physalaemus signifer group of of Nascimento, Caramaschi, and Cruz, 2005, Arq. Mus. Nac., Rio de Janeiro, 63: 308. Weber, Gonzaga, and Carvalho-e-Silva, 2006 "2005", Arq. Mus. Nac., Rio de Janeiro, 63: 678, provided a sonogram of the advertisement call. Costa and Toledo, 2013, J. Herpetol., 47: 530–538, reported on the vocal repertoire. In the Physalaemus signifer clade of Lourenço, Targueta, Baldo, Nascimento, Garcia, Andrade, Haddad, and Recco-Pimentel, 2015, Mol. Phylogenet. Evol., 92: 204–216. Hepp and Pombal, 2020, Zootaxa, 4725: 1–106, discussed this species as part of a genus-wide discussion of bioacoustical traits among the species.
