Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. W. Twente 1952 | "A Sceloporus, apparently approximately the same size as a large Sceloporus undulatus garmni Boulnger, but the dentary is more robust and possesses a deep excavation on the posterior lateral surface for the insertion of what is interpreted to be the adductor mandibularis muscle. The teeth are relatively heavy and somewhat transversely compressed at the base (pg. 71)" |
