Key to Spotted Frog Group
Until very recently, biologists only recognized one species in this group, the Spotted Frog. Genetic analysis has revealed that there is really two species. They are virtually identical, but their ranges do not appear to overlap.
24a. extreme southwestern British Columbia
Rana pretiosa (Oregon Spotted Frog)
24b. elsewhere in British Columbia, Alberta or the Yukon
Rana luteiventris (Columbia Spotted Frog)
