The Madrean alligator lizard (Elgaria kingii) is a species of lizard in the family Anguidae. The species is endemic to the southwestern United States and adjacent northwestern Mexico.

Etymology

The specific name, kingii, is in honor of Phillip Parker King, an Australian-born Royal Navy officer who surveyed the coast of South America.^[3]

Geographic range

Elgaria kingii is found from southeastern Arizona and southwestern New Mexico, United States, southward to Jalisco, Colima, Nayarit, southeastern Zacatecas, and southwestern Aguascalientes, Mexico.

Three subspecies are recognized as being valid, including the nominotypical subspecies.^[2]

Nota bene: A trinomial authority in parentheses indicates that the subspecies was originally described in a genus other than Elgaria.
