DistributionUSA (SW California, Nevada, Arizona, New Mexico),
Mexico (Baja California, Sonora, Sinaloa)

bogerti: Mexico (Sinaloa, Mazatlán). Type locality: Isla de los Chivos, en el Puerto de Mazatlán, Sinaloa.

brevipes: Mexico (Sinaloa, Sonora); Type locality: Guirocoba, 18 miles southeast Alamos, Sonora.

carmenensis: Camen Island, Gulf of Mexico, Mexico.

inusitanus: Mexico (Sonora)

Type locality: California. Restricted to Cape San Lucas, Baja California by SMITH & TAYLOR 1950.

splendidus: endemic to Isla Ángel de La Guarda.

rhodostictus: California, Arizona, Baja California

ventralis: Arizona, California, Nevada (fide BURT 1933)  
Reproductionoviparous.<br />Hybridization: Dickerson 1919 speculated that both inusitatus and plasticus “very possibly, in fact probably, intergrade with Callisaurus ventralis ventralis” (= C. d. ventralis). 
TypesHolotype: MNHN-RA 0812 (by monotypy)
Holotype: CNAR (cited as Inst. Biol. Mexico; Victoriano Rodriguez collector. [bogerti]
Holotype: AMNH 63668; J. W. Hilton collector. [brevipes]
Holotype: USNM 14895 [crinitus]
Holotype: AMNH 538, USNM 642538 [carmenensis]
Syntypes: (2) ANSP 8548, 12788; northern Lower California [gabbii]
Syntypes: AMNH 5324, USNM 64256 [inusitatus]
Holotype: USNM 51786 [myurus]
Syntypes: USNM 21504 [rhodostictus]
Holotype: USNM 64254, given as AMNH 5372, paratype: AMNH 5338 [Callisaurus splendidus]
Holotype: USNM 2670; S. W. Woodhouse collector. [ventralis]
Holotype: USNM 64255 [Callisaurus plasticus] 
DiagnosisDiagnosis: Zebra-tailed Lizards (Callisaurus draconoides) have external ear openings and the 2 black bands are farther forward on the sides and belly. Elegant (Holbrookia elegans) and Common Lesser Earless Lizards (Holbrookia maculata) have smaller black bands that are farther forward, and lack black markings on the ventral tail surface (Howland in Jones & Lovich 2009: 146). 
CommentSynonymy: Grismer (1999) synonymized Callisaurus draconoides splendidus with C. draconoides after examining species from the adjacent peninsula. These specimen cannot be distinguished clearly from the island populations of “splendidus”. BURT 1933 listed Callisaurus draconoides myurus RICHARDSON 1915 as a synonym of Callisaurus draconoides ventralis.

Type species: Callisaurus draconoides is the type species of the genus Callisaurus BLAINVILLE 1835.

Diet: a large percentage of the diet of this species (10-30%) consists of ants (Lucas et al. 2023).
