    The distribution range of Iberolacerta bonnali is restricted to the central Pyrenees und Spain and France (see map at Iberolacerta aurelioi). Like other Pyrenees Rock Lizards, Iberolacerta bonnali is a high altitude mountain species. It lives on bare rocky habitats, which may be covered with snow until early summer.

    Within its distribution range, it co-occurs with Zootoca vivipara and Podarcis muralis. Zootoca vivipara frequently shows a dark vertebral line which lacks in Iberolacerta bonnali. Furthermore, Iberolacerta bonnali has a characteristic pointed snout. Moreover, Zootoca vivipara seems to prefer well-vegetated habits (heathland) instead of rocky areas – real syntopy should be rare.

    Podarcis muralis frequently shows a dark vertebral line which lacks in Iberolacerta bonnali. Furthermore, it has dark-spotted, frequently orange throat, whereas Iberolacerta bonnali has an unspotted whitish throat. It seems that during the recent years, Podarcis muralis has been occupying increasingly high altitudes. Presumably, this leads to some crowding out of Iberolacerta bonnali.

    Iberolacerta bonnali differs from other Pyrenean Rock Lizard species by the following characters: Iberolacerta aranica has the three characteristic big masseteric scales. Iberolacerta aurelioi frequently has a yellow underside.
