P. guttatus was previously placed in the genus Elaphe, but Elaphe was found to be paraphyletic by Utiger et al. , leading to placement of this species in the genus Pantherophis. The placement of P. guttatus and several related species in Pantherophis rather than Elaphe has been confirmed by further phylogenetic studies. Many reference materials still use the synonym Elaphe guttata. Molecular data have shown that corn snakes are actually more closely related to kingsnakes (genus Lampropeltis) than they are to the Old World rat snakes with which they were formerly classified. Corn snakes have even been bred in captivity with California kingsnakes to produce fertile hybrids known as “jungle corn snakes”.
