| North American True Frogs
Lithobates Ftizinger, 1843
- 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) divided the North American (north of México) members of the Family Ranidae into two genera, the North American True Frogs (Lithobates Fitzinger, 1843) and Pacific True Frogs (Rana Linnaeus, 1758).
- Che et al. (2007 Molecular Phylogenetics and Evolution 43: 1-13) provided additional evidence to support the recommendation of Frost et al. (2006; see above) that North American ranid frogs be placed in two genera, Rana and Lithobates.
