See account (as Leptodactylus discodactylus) by Heyer, 1970, Contrib. Sci. Nat. Hist. Mus. Los Angeles Co., 191: 7–9. Duellman, 1978, Misc. Publ. Mus. Nat. Hist. Univ. Kansas, 65: 105–106, provided a brief account and characterization larvae and of the call.  Rodríguez and Duellman, 1994, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 22: 72–73, provided a brief account for the Iquitos region of northeastern Peru. See also Gascon, Lougheed, and Bogart, 1996, Biotropica, 28: 376–387, for discussion of apparent lack of geographic variation. This followed by Heyer, 1997, Proc. Biol. Soc. Washington, 110: 338–365, who discussed goegraphic variation in color pattern, morphology, and call structure. Most closely related to Adenomera and Lithodytes, according to Heyer, 1975, Smithson. Contrib. Zool., 199. Heyer, 1998, Alytes, 16: 1–24, presented evidence to place Vanzolinius deeply within a paraphyletic Leptodactylus, and likely the sister taxon of Leptodactylus diedrus. Köhler and Lötters, 1999, Bonn. Zool. Beitr., 48: 259–273, provided the Bolivian record. In the Leptodactylus melanonotus species group of de Sá, Grant, Camargo, Heyer, Ponssa, and Stanley, 2014, S. Am. J. Herpetol., 9(Spec. Issue 1): 1–123, and who provided a summary of relevant literature (adult and larval morphology, identification, advertisement call, and range) on pp. 73–74, although they excluded Bolivia from the range without discussion. Metcalf, Marsh, Torres Pacaya, Graham, and Gunnels, 2020, Herpetol. Notes, 13: 753–767, reported the species from the Santa Cruz Forest Reserve, Loreto, northeastern Peru. Carvalho, Fouquet, Lyra, Giaretta, Costa-Campos, Rodrigues, Haddad, and Ron, 2022, Syst. Biodiversity, 20 (1: 2089269): 1–31, reported on the systematics, phylogenetics, and advertisement call. Gagliardi-Urrutia, García Dávila, Jaramillo-Martinez, Rojas-Padilla, Rios-Alva, Aguilar-Manihuari, Pérez-Peña, Castroviejo-Fisher, Simões, Estivals, Guillen Huaman, Castro Ruiz, Angulo Chávez, Mariac, Duponchelle, and Renno, 2022, Anf. Loreto: 142–143, provided a brief account, photograph, dot map, and genetic barcode for Loreto, Peru. Crnobrna, Santa-Cruz Farfan, Gallegos, López-Rojas, Llanqui, Panduro Pisco, and Kelsen Arbaiza, 2023, Check List, 19: 445, provided a record from Ucayali Department, central-eastern Peru.
