Removed from the synonymy of Physalaemus gracilis by Rivero, 1961, Bull. Mus. Comp. Zool., 126: 88, where it had been placed by Parker, 1927, Ann. Mag. Nat. Hist., Ser. 9, 20: 473. Considered a synonym of Physalaemus gracilis by AJC in Duellman, 1993, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 21: 127. Duellman, 1997, Sci. Pap. Nat. Hist. Mus. Univ. Kansas, 2: 27–29, commented on the southeastern Venezuela population (as Physalaemus enesefae) and described the larvam call, and natural history. Gorzula and Señaris, 1999 "1998", Scient. Guaianae, 8: 71-74, reported on this species in Venezuela and synonymized Physalaemus enesefae. See also taxonomic and distributional comments (as Physalaemus enesefae) by Barrio-Amorós, 1999 "1998", Acta Biol. Venezuelica, 18: 48. In the Physalaemus cuvieri clade, Physalaemus cuvieri species group, of Lourenço, Targueta, Baldo, Nascimento, Garcia, Andrade, Haddad, and Recco-Pimentel, 2015, Mol. Phylogenet.
