In the Rana boylii group of North American authors. In the Rana aurora group of Dubois, 1987 "1986", Alytes, 5: 42, in the equivalent Section Amerana, subgenus Aurorana of Dubois, 1992, Bull. Mens. Soc. Linn. Lyon, 61: 322. (Although Aurorana was shown by Hillis and Wilcox, 2005, Mol. Phylogenet. Evol., 34: 305, to be paraphyletic with respect to Amerana.) Reviewed by Turner and Dumas, 1972, Cat. Am. Amph. Rept., 119: 1-2 (before the recognition of Rana luteiventris). See comment under Rana luteiventris. Stebbins, 2003, Field Guide W. Rept.

Funk, Pearl, Draheim, Adams, Mullins, and Haig, 2008, Mol. Phylogenet. Evol., 49: 198-210, reported on molecular phylogeographics.
