Remarks: Frost et al. (2006) revised the genus Rana and most of the North, Central and South American "true frogs" were seperated from this taxon and placed into the new genus Lithobates (Frost et al., 2006; Crother, 2008; Collins and Taggart, 2009).  Scientific and standard English names follow Crother (2008).
