Comment

In the Physalaemus gracilis group of Nascimento, Caramaschi, and Cruz, 2005, Arq. Mus. Nac., Rio de Janeiro, 63: 310. See account by Cei, 1980, Monit. Zool. Ital., N.S., Monogr., 2: 399-402, and brief account by Klappenbach and Langone, 1992, An. Mus. Nac. Hist. Nat. Montevideo, Ser. 2, 8: 195-196. See comment under Physalaemus fischeri. Achaval and Olmos, 2003, Anf. Rept. Uruguay, ed. 2: 30, provided a brief account and photograph for the Uruguay population. 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 gracilis species group, of Lourenço, Targueta, Baldo, Nascimento, Garcia, Andrade, Haddad, and Recco-Pimentel, 2015, Mol. Phylogenet. Evol., 92: 204–216.
