Identification. A medium-sized skink (max. SVL = 75.8 mm). Dorsum olive-brown with dark flecks, a dark brown to black lateral band running from the snout to the tail, bordered by a white stripe below. Supra- and infralabials characteristically white with a yellowish to orange patch near the forelimb insertion (Figure 8O). In reproductively active males, the white colouration on the labials is replaced by a yellowish colouration (Figure 8N). Specimens from Cabinda Province are genetically identical to material from Lekoumou, Republic of the Congo (GenBank: KY683566).

Biology and distribution. An arboreal skink widely distributed in West Africa, from Guinea Bissau to Angola (Allen et al. 2019). In Cabinda Province, the species was found in all four ecological zones considered, moving actively during the day on tree trunks and branches.
