In the Physalaemus biligonigerus group of Nascimento, Caramaschi, and Cruz, 2005, Arq. Mus. Nac., Rio de Janeiro, 63: 309. A sibling species of Physalaemus biligonigerus according to the original publication. Compared morphometrically with Physalaemus biligonigerus by Laurent, 1969, Acta Zool. Lilloana, 25: 81-96. Brusquetti and Lavilla, 2006, Cuad. Herpetol., 20: 25, suggested that this species likely occurs in adjacent Paraguay. Vera Candioti, 2007, Zootaxa, 1600: 1–175, reported on detailed larval morphology. Gómez and Kehr, 2011, Phyllomedusa, 10: 143-151, reported on developmental plasticity of larvae. Weiler, Núñez, Airaldi, Lavilla, Peris, and Baldo, 2013, Anf.
