Endemic to South Africa and adjacent southwestern Namibia (McLachlan 1981, Bates et al. 2014). In South Africa, it has a large distribution, occurring mainly along the West Coast in the winter rainfall areas of the Northern and Western Cape Provinces. Although originally distributed as far south as Cape Town (McLachlan 1981), contemporary populations throughout the heavily modified Cape Flats are scant and sightings are now rare. Several records from the Nama-Karoo, including the De Aar - Hanover and Beaufort West areas, may refer to Agama aculeata aculeata, and are excluded from the map. Two isolated subpopulations in grassland habitat in the northwestern Free State (referred to as A. makarikarica by DeWaal 1978), may represent a cryptic taxon.
If the Free State populations are referable to a new taxon, then a separate assessment will be needed.
