The Family Polychrotidae is a member of the Order Squamata. Here is the complete "parentage" of Polychrotidae:

The Family Polychrotidae is further organized into finer groupings including:

Anolis is a genus of lizards belonging to the family Polychrotidae. With nearly 400 species, Anolis represents the world's most species rich amniote genus. Several species of Anolis are occasionally ascribed to the genus Norops, but the validity of the Norops genus is not widely accepted. The Green Anole (Anolis carolinensis) has recently become the first reptile (not counting birds) to have its complete genome sequenced. [more]

Norops is the proposed generic name for 150 lizard species traditionally classified in the genus Anolis (family, Iguanidae). Guyer and Savage (1986) applied this name to a group that Etheridge (1959) designated the "beta anoles" on the basis of skeletal characters that distinguished them from all other anole species (i.e., "the alpha anoles"). Although Norops is clearly a distinct, monophyletic group, it renders the "alpha anoles" paraphyletic. Guyer and Savage's proposed remedy for this problem involved the designation of four additional genera within the "alpha anoles". However, three of these genera are not supported as monophyletic by recent phylogenetic studies (Jackman et al. 1998, Poe 2004, Nicholson et al. 2005). As a result, recognition of Norops as a genus is premature and likely to confound efforts to study and conserve anoles. This position is stated explicitly in recent phylogenetic studies: [more]
