'''''Coleonyx''''' is a [[genus]] of terrestrial [[gecko]]s commonly referred to as '''banded geckos'''. [[Species]] of ''Coleonyx'' are found in the [[southwestern United States]], [[Mexico]], and [[Central America]]. Most banded Geckos enjoy dry, warm weather which is why they are typically found in the Peninsular Desert.<ref>Introgression obscures lineage boundaries and phylogeographic history in the western banded gecko, Coleonyx variegatus (Squamata: Eublepharidae)</ref> Some, however, prefer humid forests. They are relatively small lizards, measuring about {{convert|5|-|6|in|cm|abbr=on}} inches in total length (including tail). They are [[nocturnal]] and are found primarily in dry, rocky [[habitat]]s. Banded Geckos have preyed by snakes, their main predators being [[Rattlesnake|rattlesnakes]] and [[Glossy snake|glossy snakes]]. Banded Geckos can decipher how they should react when they obtain a chemical cue based on their knowledge of the predator. A main resource they use to distract the predator is losing their tail or escaping quickly.<ref>Know Thine Enemy: Predator Identity Influences the Response of Western Banded Geckos (Coleonyx variegatus) to Chemosensory Cues</ref> Banded Geckos possess heteromorphic euchromatic sex chromosomes which play a large role in their historical contingency. <ref>Microsatellite distribution on sex chromosomes at different stages of heteromorphism and heterochromatinization in two lizard species (Squamata: Eublepharidae: Coleonyx elegans and Lacertidae: Eremias velox)</ref>
