Kingsnakes are colubrid New World members of the genus Lampropeltis, which includes milk snakes and four other species. Among these, about 45 subspecies are recognized. They are nonvenomous and ophiophagous in diet.
Kingsnakes vary widely in size and coloration. They can be as small as 24" (61cm) or as long as 60" (152cm).[3] Some kingsnakes are colored in muted browns to black, while others are brightly marked in white, reds, yellows, grays, and lavenders that form rings, longitudinal stripes, speckles, and saddle-shaped bands.[4]
Most kingsnakes have quite vibrant patterns. Some species, such as the scarlet kingsnake, Mexican milk snake, and red milk snake, have coloration and patterning that can cause them to be confused with the highly venomous coral snakes. One of the mnemonic rhymes to help people distinguish between coral snakes and their nonvenomous lookalikes in the United States is "red on black, a friend of Jack; red on yellow, kill a fellow". Other variations include "red on yellow kill a fellow, red on black venom lack",[5][6] and referencing the order of traffic lights "yellow, red, stop!" All these mnemonics apply only to the three species of coral snakes native to the southern United States: Micrurus fulvius (the eastern or common coral snake), Micrurus tener (the Texas coral snake), and Micruroides euryxanthus (the Arizona coral snake). Coral snakes found in other parts of the world can have distinctly different patterns, such as having red bands touching black bands, having only pink and blue bands, or having no bands at all.
Lampropeltis includes the Greek words for "shiny shield":[7] λαμπρός lampro(s) ("shiny") + πέλτη pelt(ē) ("peltē shield") + -is (a Latin suffix). The name is given to them in reference to their smooth, enamel-like dorsal scales.[8]
Taxonomic reclassification of the kingsnakes is an ongoing process and different sources often disagree, one source granting full species status to a group of these snakes that another source considers a subspecies group. In the case of L. catalinensis, for example, only a single specimen exists, so classification is not necessarily finite. In addition, hybridization between species with overlapping geographic ranges is not uncommon, confusing taxonomists further.
