| Diagnosis | Diagnosis: A species of the M. olivieri complex characterized by the following combination of characters: (a) low number of eyelid scales (5–6); (b) with two clearly larger scales, like M. guttulata (several sub-equal scales or rarely 1–2 larger scales in the other species of the M. olivieri complex); (c) small black dots on the edge of the eyelids (mostly visible in dead animals preserved in ethanol); (d) more elongated snout with more prominent nostrils than the other species of the olivieri complex; (e) adult coloration in life (Figure 7) different from all other species of the complex (see Figure S5 and comparison below) (Pizzigalli et al. 2021).

| Etymology | The species epithet “adrarensis” refers to the Adrar Atar region because the new species was first suspected when seeing specimens from this region. |
