註釋

Mitochondrial DNA sequences were obtained for 16 species representing all nominal genera of Cordylidae (Platysaurus, Chamaesaura, Cordylus, and Pseudocordylus). Gerrhosauridae and Teiidae were used as first and second outgroups. Results indicate that the oviparous Platysaurus is the sister taxon of the remaining cordylids (all of which are ovoviviparous). Within the ovoviviparous group Cordylus is paraphyletic with respect to Chamaesaura and Pseudocordylus. No evidence of Pseudocordylus monophyly was discovered. The three species of Chamaesaura and the seven species of Pseudocordylus are transferred to Cordylus to render a monophyletic taxonomy.
