Resurrected from the synonymy of Pseudopaludicola falcipes by Haddad and Cardoso, 1987, Pap. Avulsos Zool., São Paulo, 36: 287-300. See comment under Pseudopaludicola ternetzi. Alcalde and Williams, 2004, Cuad. Herpetol., 18: 75-76, provided records for the provinces of Santa Fé and Entre Ríos in Argentina. Brusquetti and Lavilla, 2006, Cuad. Herpetol., 20: 18, briefly discussed the range in Paraguay. Silva, Santos, Alves, Sousa, and Annunziata, 2010, Sitientibus, Ser. Cienc. Biol., 7: 334-340, provided records for Piauí, Brazil. See comment under Pseudopaludicola ameghini with which many records probably apply. Pansonato, Strüssmann, Mudrek, and Martins, 2013, Zootaxa, 3620: 147–162, provided acoustic and morphometric data. Roberto, Cardozo, and Ávila, 2013, Zootaxa, 3636: 348–360, provided discussion that suggests that the identity of specimens from northeastern Brazil requires additional revision. Weiler, Núñez, Airaldi, Lavilla, Peris, and Baldo, 2013, Anf. Paraguay: 111, provided a brief account, image, and dot map for Paraguay. Pansonato, Mudrek, Simioni, Martins, and Strüssmann, 2014, Adv. Zool., 2014(Art. 563165): 1–13, reported on morphological and acoustic variation. Schulze, Jansen, and Köhler, 2015, Zootaxa, 4016: 68–69, described, diagnosed, and pictured the larva. Oliveira, Santos, Souza, Lima-Ribeiro, Vergilio, Zórtea, Silva, Melo, Guilherme, Vaz-Silva, and Morais, 2019, Herpetol. Notes, 12: 492, reported the species from southwestern Goíás, Brazil, and discussed natural history. Dubeux, Silva, Nascimento, Gonçalves, and Mott, 2019, Rev. Nordestina Zool., 12: 18–52, summarized the literature on larval morphology. See Dubeux, Nascimento, Lima, Magalhães, Silva, Gonçalves, Almeida, Correia, Garda, Mesquita, Rossa-Feres, and Mott, 2020, Biota Neotrop., 20 (2: e20180718): 1–24, for characterization and identification of larvae north of the Rio São Francisco in the Atlantic Forest of northeastern Brazil. Vaz-Silva, Maciel, Nomura, Morais, Guerra Batista, Santos, Andrade, Oliveira, Brandão, and Bastos, 2020, Guia Ident. Anf. Goiás e Dist. Fed. Brasil Central: 148–149, provided an account for Goiás and the D.F., Brazil. Dubeux, Gonçalves, Ramos, Melo, Silva, and Mott, 2020, Herpetol. Notes, 13: 997–1002, provided a record for Pedra Talhada Biological Reseerve, Quebrangulo Municipality, Alagoas, Brazil, and commented on natural history and range. Reported from the Environmental Protection Area of Catolé and Fernão Velho, Alagoas, Brazil, by Dubeux, Nascimento, Gonçalves, and Mott, 2021, Pap. Avulsos Zool., São Paulo, 61 (e20216176): 1–10, who provided a key to the frogs of that region. Palmeira, Gonçalves, Dubeux, Lima, Lambertini, Valencia-Aguilar, Jenkinson, James, Toledo, and Mott, 2022, Cuad. Herpetol., 36: 65–75, reported on habitat in Natural Heritage Reserve Mata Estrela, Baía Formosa, Rio Grande do Norte state, Brazil. Porto, Fazolato, Marques, Batalha, Napoli, Garda, Carvalho, and Fernandes, 2022, Amphibia-Reptilia, 43: 315–329, identified 10 mtDNA matrilines within the species.
