Sonora savagei can be distinguished from S. fasciata, S. cincta, S. stramineus, and S. punctatissiumus by the lack of dark spots in pale bands, broad contact of the internasals with the frontal scale (Holm 2008), separated and reduced prefrontal scales, an enlarged frontal scale, and (Grismer et al. 2002). Sonora savagei is the only member of the genus Sonora on Isla Ceralvo (Cox et al. 2018: 973).
