In the Physalaemus henselii group of Nascimento, Caramaschi, and Cruz, 2005, Arq. Mus. Nac., Rio de Janeiro, 63: 310. Tomatis, Baldo, Kolenc, and Borteiro, 2009, J. Herpetol., 43: 555–560, rejected this group as nonmonophyletic. See comment under Physalaemus fernandezae. Reviewed by Barrio, 1964, Acta Zool. Lilloana, 20: 285–305; and Cei, 1980, Monit. Zool. Ital., N.S., Monogr., 2: 405406. See brief nomenclatural account by Klappenbach and Langone, 1992, An. Mus. Nac. Hist. Nat. Montevideo, Ser. 2, 8: 196. See comment under Physalaemus kroyeri. Achaval and Olmos, 2003, Anf. Rept. Uruguay, ed. 2: 31, provided a brief account and photograph for the Uruguay population. Kolenc, Borteiro, Tedros, Núñez, and Maneyro, 2006, Zootaxa, 1360: 41–50, reported on larval morphology. Maneyro, Núñez, Borteiro, Tedros, and Kolenc, 2008, Iheringia, Zool., 98: 210–214, reported on advertisement call in Uruguayan populations. Brusquetti and Lavilla, 2006, Cuad. Herpetol., 20: 25, noted that although this species probably occurs in Paraguay there are at present no voucher specimens to document it there. In the Physalaemus cuvieri clade, Physalaemus henselii species group, 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.
