Comment
In the Leptodactylus pentadactylus group of Heyer, 1972, Contrib. Sci. Nat. Hist. Mus. Los Angeles Co., 231: 1-8, and Heyer, 1979, Smithson. Contrib. Zool., 301: 1–43. Rodríguez and Duellman, 1994, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 22: 66–67, provided a brief account for the Iquitos region of northeastern Peru. Lescure and Marty, 2000, Collect. Patrimoines Nat., Paris, 45: 244–245, provided a photo and brief account for French Guiana. Gorzula and Señaris Vasquez, 1999 "1998", Scient. Guaianae, 8: 57–58, commented on distribution in Venezuela and noted that the original description was based on a juvenile, which did not show the typically adult color pattern. Murphy, 1997, Amph. Rept. Trinidad Tobago: 86–87, provided a brief account for Trinidad, although subsequent authors have regarded this record as requiring verification. Heyer, 2005, Arq. Zool., São Paulo, 37: 269–348, provided an extensive discussion and account of variation. Duellman, 2005, Cusco Amazonico: 282–283, provided an account (adult and larval morphology, description of the call, life history). Heyer, de Sá, and Rettig, 2005, in Ananjeva and Tsinenko (eds.), Herpetol. Petropolitana: 35–39, reported on the advertisement call. Heyer and Heyer, 2006, Cat. Am. Amph. Rept., 807: 1-12, provided a review. Fouquet, Gilles, Vences, Marty, Blanc, and Gemmell, 2007, PLoS One, 10 (e1109): 1–10, provided molecular evidence that this is a species complex. Kok and Kalamandeen, 2008, Intr. Taxon. Amph. Kaieteur Natl. Park: 214–215, provided an account and suggested that the taxon may be a species complex. See account for Suriname population by Ouboter and Jairam, 2012, Amph. Suriname: 234–237. França and Venâncio, 2010, Biotemas, 23: 71–84, provided a record for the municipality of Boca do Acre, Amazonas, with a brief discussion of the range.

Issue 1): 1–123, and who provided a summary of relevant literature (adult and larval morphology, identification, advertisement call, and range) on pp. 51–52. See Barrio-Amorós, Rojas-Runjaic, and Señaris Vasquez, 2019, Amph. Rept. Conserv., 13 (1: e180): 91, for comments on range and literature.
