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.
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]
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.
Anguidae refers to a large and diverse family of lizards native to the Northern Hemisphere. Common characteristics of this group include a reduced supratemporal arch, striations on the medial faces of tooth crowns, osteoderms, and a lateral fold in the skin of most taxa. The group is divided into two living subfamilies, the legless Anguinae, which contains slow worms and glass lizards, among others, found across the Northern Hemisphere, and Gerrhonotinae, which contains the alligator lizards, native to North and Central America. The family Diploglossidae was also formerly included. The family contains about 87 species in 8 genera.
Elgaria is a genus of New World lizards in the family Anguidae. Their common name is western alligator lizards.
Gerrhonotus is a genus of anguid lizards that are commonly referred to as alligator lizards, due to a vague resemblance to an alligator. Most species are restricted to Mexico, but a few range into Guatemala or Texas, and G. rhombifer is from Costa Rica and Panama. Along with glass lizards (Ophisaurus) and many other lizards, alligator lizards have the ability to regrow their tail.
The southern alligator lizard is a common species of lizard in the family Anguidae. The species is native to the Pacific coast of North America. It ranges from Baja California to the state of Washington and lives in a variety of habitats including grasslands, chaparral, forests, and even urban areas. In dry climates, it is likely to be found in moist areas or near streams. There are five recognized subspecies.
The northern alligator lizard is a species of medium-sized lizard in the family Anguidae. The species is endemic to the North American west coast.
An alligator lizard is any one of various species of lizards in the family Anguidae that have some shared characteristics. The term may specifically refer to:
The western whiptail is a species of lizard in the family Teiidae. The species is found throughout most of the southwestern United States and northern Mexico. Most of its populations appear stable, and it is not listed as endangered in any of the states comprising its range. It lives in a wide variety of habitats, including deserts and semiarid shrubland, usually in areas with sparse vegetation; it also may be found in woodland, open dry forest, and riparian growth. It lives in burrows. Major differences between this species and the checkered whiptail include the lack of enlarged scales anterior to the gular fold and the presence of enlarged postantebrachial scales. It was previously known as Cnemidophorus tigris, until phylogenetic analyses concluded that the genus Cnemidophorus was polyphyletic. Since it does not migrate, a number of forms have developed in different regions, several of which have been given subspecific names – for example the California whiptail, Aspidoscelis tigris munda.
The Texas alligator lizard is a species of lizard in the subfamily Gerrhonotinae of the family Anguidae. The species is endemic to the central region of the American state of Texas, and south into adjacent northern Mexico.
The Texas spotted whiptail is a species of long-tailed lizard, in the family Teiidae. The species is endemic to the south central and southwestern United States and northern Mexico. Six subspecies are recognized as being valid.
Holbrookia maculata, commonly known as the lesser earless lizard, is a species of lizard in the family Phrynosomatidae. The species is native to the southwestern and central United States and northern Mexico. There are eight recognized subspecies.
Abronia deppii, Deppe's arboreal alligator lizard, is an endangered species of arboreal alligator lizard in the family Anguidae. The species was described in 1828 by Arend Friedrich August Wiegmann, and it is endemic to Mexico.
Abronia matudai, Matuda's arboreal alligator lizard, is a species of endangered arboreal alligator lizard in the family Anguidae. The species, which was originally described in 1946 by Norman Hartweg and Joseph Tihen, is endemic to Central America.
Abronia ochoterenai, Ochoterena's arboreal alligator lizard or Northern Chiapas arboreal alligator lizard, is a species of arboreal alligator lizard in the family Anguidae. The species, which is native to extreme southern Mexico, was described in 1939 by Rafael Martín del Campo.
The isthmian alligator lizard is a species of lizard of the Anguidae family. G. rhombifer is found in both Costa Rica and Panama. Unlike many lizards near its habitat, individuals have lateral folds. They give birth to live young. Gerrhonotus rhombifer had not been seen for fifty years, prior to being rediscovered in 2000 near Golfito, and is one of the rarest species of lizard in Costa Rica.
Abronia moreletii, commonly known as Morelet's alligator lizard, is a species of lizard in the family Anguidae. The species is endemic to Central America.
Gerrhonotus farri, also known commonly as Farr's alligator lizard and the Tamaulipan alligator lizard, is a species of lizard in the family Anguidae. The species is native to northeastern Mexico.
Gerrhonotus liocephalus, the Texas alligator lizard or Wiegmann's alligator lizard, is a species of lizard of the Anguidae family. It is found in Texas, Mexico and Guatemala.
Gerrhonotus lugoi, Lugo's alligator lizard, is a species of lizard of the Anguidae family. It is found in Mexico.
Abronia gadovii, also known commonly as Gadow's alligator lizard and el escorpión de Gadow in Mexican Spanish, is a species of lizard in the family Anguidae. The species is endemic to the highlands of the Sierra Madre del Sur in Guerrero and Oaxaca, Mexico. Two subspecies are recognized:
