Identification. A large lizard (SVL = 140–175 mm) with stout body and head. Four supraciliary scales, 22–24 longitudinal dorsal scale rows (Bates et al. 2013). Dorsum light brown with scattered white lateral scales, and white and black lateral stripes from occipitals to tail, and usually light cream broken vertebral stripe. Specimens collected in Cabinda Province differ by 2% (16S p -distance) from material collected from Loulema, Republic of the Congo (GenBank: KF717399).

Biology and distribution. A widely distributed species in western and central Africa (Piettersen et al., 2021). An elusive and shy lizard that can be frequently found in bushveld and savannahs. In Cabinda Province, it is commonly encountered in the Littoral Peneplain area and Coastal Drier Belt, moving rapidly between grassland and bushes. However, the species was also recorded in patches of secondary forest at Upper Mayombe.
