 Green, 1985, Herpetologica, 41: 262–267, reported natural hybridization with Rana cascadae. 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. Amph., Ed. 3: 228, provided a brief account, figure, and map (and who commented on the disappearance of this species from large areas of its former distribution). Funk, Pearl, Draheim, Adams, Mullins, and Haig, 2008, Mol. Phylogenet. Evol., 49: 198–210, reported on molecular phylogeographics.
