In this study the author analyzes the phylogenetic relationships among the genera and species of alligator lizards (Squamata: Anguidae: Gerrhonotinae).
The subfamily consists of six monophyletic genera: Coloptychon, Gerrhonotus, Elgaria, Barisia, Mesaspis, and Abronia.
The author reviews the history of gerrhonotine taxonomy, provides a key to, and diagnoses of, all gerrhonotine taxa, and discusses taxonomic and biogeographic implications of gerrhonotine relationships.

Within gerrhonotines, the moreleti group, the gadovi-imbricata group, and Abronia are closest, and Elgaria is their sister taxon.
These taxa, together with Gerrhonotus and Coloptychon, form an unresolved trichotomy within the Gerrhonotinae.
Many of the characters that distinguish Abronia from other gerrhonotines may be paedomorphic.
