The Crotaphytidae, or collared lizards, are a family of desert-dwelling reptiles native to the Southwestern United States and northern Mexico. Alternatively they are recognized as a subfamily, Crotaphytinae, within the clade Pleurodonta. They are very fast-moving animals, with long limbs and tails; some species are capable of achieving bipedal running at top speed. This species is carnivorous, feeding mainly on insects and smaller lizards. The two genera contain 12 species.
The Iguanidae is a family of lizards composed of the iguanas, chuckwallas, and their prehistoric relatives, including the widespread green iguana.
Ctenosaura is a lizard genus commonly known as spinytail iguanas or ctenosaurs. The genus is part of the large lizard family Iguanidae and is native to Mexico and Central America. The name is derived from two Greek words: κτενός, meaning "comb", and σαύρα, meaning "lizard".

The spiny weapontail is a species of lizard belonging to the monotypic genus Hoplocercus in the family Hoplocercidae. The species is found in the Cerrado and adjacent Cerrado–Amazon mosaics in Brazil and Bolivia.
Alopoglossus is a genus of lizards in the monogeneric family Alopoglossidae. The genus is distributed from Costa Rica in Central America to northern South America.
Iguania is an infraorder of squamate reptiles that includes iguanas, chameleons, agamids, and New World lizards like anoles and phrynosomatids. Using morphological features as a guide to evolutionary relationships, the Iguania are believed to form the sister group to the remainder of the Squamata, which comprise nearly 11,000 named species, roughly 2000 of which are iguanians. However, molecular information has placed Iguania well within the Squamata as sister taxa to the Anguimorpha and closely related to snakes. The order has been under debate and revisions after being classified by Charles Lewis Camp in 1923 due to difficulties finding adequate synapomorphic morphological characteristics. Most iguanians are arboreal but there are several terrestrial groups. They usually have primitive fleshy, non-prehensile tongues, although the tongue is highly modified in chameleons. Today they are scattered occurring in Madagascar, the Fiji and Friendly Islands and Western Hemisphere.

Enyalioides sophiarothschildae, or the Rothschild's woodlizard, is a species of lizards in the family Hoplocercidae. It is endemic to the Amazonian slopes of the Cordillera Central in northeastern Peru. It differs from its congeneric species by possessing homogeneous (size) caudal scales on each caudal segment, a white gular region that has a black patch as well as turquoise scales in males, and immaculate white labials and chin.
Enyalioides anisolepis the rough-scaled woodlizard, is a species of lizards in the family Hoplocercidae. It is known from the Amazonian slopes of the Andes in southern Ecuador and northern Peru. It differs from its congeneric species by possessing scattered, projecting large scales on its dorsum, flanks, and hind limbs; a well-developed vertebral crest, with vertebrals on its neck being about three times in size compared to those between the animal's hind limbs.
Enyalioides altotambo, the Alto Tambo woodlizard, is a species of lizards in the family Hoplocercidae. It is endemic to the tropical northwestern Andes in Ecuador. It is named after its type locality, Alto Tambo in the Esmeraldas Province. It differs from its congeneric species by possessing smooth and homogeneous (size) dorsal scales, a brown iris, and lacking circular and keeled scales on its flanks.
Enyalioides cofanorum, also known commonly as the Cofan woodlizard, Duellman's dwarf iguana, and lagartija de palo cofanes in Spanish, is a species of lizard in the family Hoplocercidae. The species is native to northwestern South America.
Enyalioides oshaughnessyi, the red-eyed woodlizard or O'Shaughnessy's dwarf iguana, is a species of lizards in the family Hoplocercidae. It occurs in southern Colombia and northern Ecuador. The specific name oshaughnessyi honors Arthur O'Shaughnessy, a British herpetologist.
Enyalioides touzeti, also known as Touzet's woodlizard, is a species of lizard in the family Hoplocercidae. It occurs on the western Andean slopes of southwestern Ecuador and northern Peru.
