Rept., 666: 1–3 (who provided a detailed account, literature review, and reported on advertisement call), and Lescure and Marty, 2000, Collect. Patrimoines Nat., Paris, 45: 44 (who also reported on advertisement call). De la Riva, Köhler, Lötters, and Reichle, 2000, Rev. Esp. Herpetol., 14: 57, considered this species possibly to occur in Bolivia. Duellman, 1997, Sci. Pap. Nat. Hist. Mus. Univ. Kansas, 2: 9, commented on a population in Venezuela. Barrio-Amorós, 1999 "1998", Acta Biol. Venezuelica, 18: 4, commented on the Venezuelan range. Langone and Segalla, 1997, Cuad. Herpetol., 11: 87–88, reported the species in the Estado de Rondônia, Brazil. Bernarde, Machado, Macedo-Bernarde, Monção, and Silva, 2007, Check List, 2(3): 5–6, provided an additional record for Rondônia, Brazil. Kok and Kalamandeen, 2008, Intr. Taxon. Amph. Kaieteur Natl. Park: 110–113, provided a brief, but informative, account. See account for Suriname population by Ouboter and Jairam, 2012, Amph. Suriname: 16–19.
