Taxonomic Comments:
Frost, Grant, Faivovich, Bain, Haas, Haddad, De Sá, Channing, Wilkinson, Donnellan, Raxworthy, Campbell, Blotto, Moler, Drewes, Nussbaum, Lynch, Green & Wheeler (2006. The Amphibian Tree of Life. Bulletin of the American Museum of Natural History 297: 1-370) placed this species in the genus Lithobates (Fitzinger, 1843). The standard common name remains Lowland Leopard Frog. Oláh-Hemmings, V., J. R. Jaeger, M. J. Sredl, M. A. Schlaepfer, R. D. Jennings, C. A. Drost, D. F. Bradford & B. R. Riddle (2010. Phylogeography of declining Relict and Lowland Leopard Frogs in the desert Southwest of North America. Journal of Zoology. 280: pp. 343-354) demonstrated that this taxon was a species distinct from Lithobates onca and that it probably consisted of two evolutionary species.
