Pantherophis

Pantherophis is a genus of nonvenomous colubrid snakes endemic to North America and Central America, commonly called rat snakes, fox snakes, and corn snakes. All are powerful constrictors and help control rodent populations. Some taxonomic classification systems have accepted the proposed classification, while others have not. Although Pantherophis was originally proposed in 1843, in more recent history, these species were placed in the genus Elaphe. In 2002, Utiger et al. raised a taxonomic suggestion to resurrect the genus Pantherophis based on mitochondrial DNA evidence suggesting the New World rat snakes are more closely related to king snakes than to the Old World rat snakes. This was confirmed by later phylogenetic studies.However, the International Commission on Zoological Nomenclature rejected the renaming, thus Elaphe remains the more widely recognized and broadly accepted genus name. The ITIS now identifies all species names that use Pantherophis as "valid" names – no longer using Elaphe.
