Comment

See account (as Leptodactylus discodactylus) by Heyer, 1970, Contrib. Sci. Nat. Hist. Mus. Los Angeles Co., 191: 7-9. 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.
