DiagnosisDEFINITION. Coleonyx variegatus is a medium-sized gecko (maximum snout-vent length 75 mm in females; 68 mm in males) with four or more preanal pores in an uninterrupted row, and no enlarged dorsal tubercles. The base of the cloacal spur is constricted, and its distal end is pointed. The color pattern in adults ranges from broad unbroken bands to large spots in adults, but juveniles are always banded [Dixon 1970]. 
CommentSynonymy: GRISMER (1999) synonymized Coleonyx variegatus slevini with the nominate form based on scale counts: slevini has 3-5 postmental scales and adjacent peninsular populations of C. variegatus have 4-7. Also, slevini has 5-7 dark body bands and adjacent peninsular C. variegatus has 4-6. The subspecies C. v. bogerti was considered a junior synonym of C. v. variegatus by de Queiroz et al. (2017).
