The Polychrotidae family of iguanian lizards contains the living genus Polychrus (commonly called bush anoles) and the extinct genus Afairiguana. The family was once thought to encompass all anoles, including those in the genus Anolis (which are commonly included in the family Dactyloidae). However, recent studies of the evolutionary relationships of anoles based on molecular information suggests that Polychrus is not closely related to Anolis, and therefore not part of Dactyloidae.
