Taxonomic notes and synonyms listed
The morphological diversity of this species complex is not adequately reflected in current subspecific divisions (Auliya and Koch 2020). This species is divided into three subspecies which occupy distinct geographical regions and can be identified by size, tail shape, and the number of bands on the body and tail. Varanus griseus griseus has a rounded tail and highest number of bands, Varanus griseus caspius reaches the largest size and has a laterally compressed tail, while Varanus griseus koniecznyi is the smallest subspecies and has the fewest bands (Stanner 2004).

Assessment rationale/justification
Within the United Arab Emirates, this species is widespread throughout all of the mainland desert regions excluding the Hajar Mountains. It is listed as Least Concern in view of its wide distribution, presumed large population, presence in several Protected Areas, it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
