Polychrus acutirostris
Scientific classification
Kingdom: Animalia
Phylum: Chordata
Subphylum: Vertebrata
Class: Reptilia
Order: Squamata
Suborder: Lacertilia
Infraorder: Iguania
Family: Iguanidae
Subfamily: Polychrotinae


The Polychrotinae subfamily (sometimes misclassified as the now invalid Polychrotidae family[1]) of iguanian lizards contains the living genus Polychrus (commonly called bush anoles) and the extinct genus Afairiguana.[2] The Polychrotidae family was once thought to encompass all anoles, including those in the genus Anolis (which are now included in the family Dactyloidae). However, recent studies of the evolutionary relationships of anoles based on molecular information suggest that Polychrus is not closely related to Anolis. It is therefore not part of Dactyloidae and instead is included in the family Iguanidae and its subfamily, Polychrotinae.
