Holotype: MCZ 17972, paratypes in ZMB and NMW [barbouri] |
| Diagnosis | Diagnosis (genus): Dicrodon and Teius are the only teiids with transversely oriented, bicuspid teeth. Unlike Teius (characters in parentheses), Dicrodon lacks an apical basin on its hemipenis (basin present) and has fused frontoparietals (paired), a fifth toe with four phalanges (fifth toe vestigial, reduced to small nub), and sharply keeled distal digital lamellae under the fourth toe (weakly keeled or smooth). In addition, the first supraocular usually broadly contacts the second supraocular (separated by complete row of granular scales) in Dicrodon, although this character shows some regional variation (Fugler 1973).

| Comment | Synonymy that of PETERS & DONOSO-BARROS 1970.
Type species: Dicrodon guttulatum DUMÉRIL & BIBRON 1839 is the type species of the genus Dicrodon DUMÉRIL & BIBRON 1839.
Comparisons: Presch 1974: 24 compares character states across the genera Ameiva, Cnemidophorus, Kentropyx, Dicrodon, Teius, Callopistes, Tupinambis, Crocodilurus, and Dracaena. |
| Etymology | Probably named after Latin gutta = drop, for the drop-shaped head; alternatively for the spots on the back.
The genus name Dicrodon is a masculine noun in the nominative singular derived from the Greek prefix di and noun odontos and refers to the bifid posterior teeth characteristic of this genus. Genus names ending in -odon are typically masculine.
Dicrodon barbouri was named after Thomas Barbour, MCZ. |
