Common names: corn snakes, fox snakes, rat snakes, ratsnakes.
Elaphe is a genus of non-venomous colubrid snakes found in North and Central America. All are powerful constrictors and valuable allies to man in his efforts to control rodent populations. Ten species are currently recognized.

Taxonomy

Utiger et al. (2002) argued that North American Rat Snakes of the genus Elaphe are a monophyletic group and thus separate from Old World members of the genus. They therefore resurrected the available name Pantherophis Fitzinger for all North American taxa (north of Mexico).

Crother et al. (2003) rejected the taxonomic change to Pantherophis, preferring to retain the current concept of Elaphe pending further review.
