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.
