Kingsnakes are colubrid New World members of the genus Lampropeltis, which includes 26 species. Among these, about 45 subspecies are recognized. They are nonvenomous and ophiophagous in diet.
Pituophis is a genus of nonvenomous colubrid snakes, commonly referred to as gopher snakes, pine snakes, and bullsnakes, which are endemic to North America.
Pituophis catenifer affinis, commonly known as the Sonoran gopher snake, is a nonvenomous subspecies of colubrid snake that is endemic to the southwestern United States. It is one of six recognized subspecies of the gopher snake, Pituophis catenifer.
The eastern racer, or North American racer, is a species of nonvenomous snake in the family Colubridae. The species is endemic to North America and Central America. Eleven subspecies, including the nominotypical subspecies, are recognized, which as a group are commonly referred to as the eastern racers. The species is monotypic in the genus Coluber.
The Cape gopher snake or Baja gopher snake is a species of nonvenomous colubrid snake endemic to extreme southern Baja California Sur, Mexico. They have become increasingly popular companions for people interested in the exotic pet trade, due to their extreme color variations and relatively docile behavior. It was previously considered to be a subspecies of Pituophis catenifer. There has been controversy whether the Baja Gopher Snake is a lower classification of the Cape Gopher Snake. Some say the Baja Gopher Snake should be in a separate sub-species of Pituophis Vertebralis Bimaris, while Cape Gopher Snakes should remain Pituophis Vertebralis Vertebralis. Many people mistake the two as the same sub species and have cased some cross-breeding between the two. In captivity the bloodlines are nearly all related and breeding has become especially difficult in terms of keeping the bloodlines alive.
Pituophis melanoleucus, commonly known as the eastern pine snake, is a species of nonvenomous snake in the family Colubridae. The species is endemic to the eastern United States. Three subspecies are currently recognized as being valid.

Lampropeltini is a tribe of colubrid snake endemic to the New World. These include the kingsnakes, milk snake, corn snake, gopher snakes, pine snakes, and bullsnakes. At least 51 species have been recognized and the group have been heavily studied for biogeography, morphology, ecology, and phylogenetics. The internal relationships among the genera has been disputed, but generally the most supported placement of the genera are as follows:
Pituophis deppei, commonly known as the Mexican bullsnake and the Mexican pine snake, is a species of nonvenomous colubrid snake endemic to Mexico. There are two recognized subspecies.
Pituophis lineaticollis, commonly known as the Middle American gopher snake or the cincuate bull snake, is a species of nonvenomous snake in the family Colubridae. The species is native to Guatemala and southeastern Mexico. There are two recognized subspecies.
