  • Subsp. tiliguerta, male: I / Sardinia / Sette Fratelli, 31.03.2007 - Podarcis tiliguerta is an endemic species of Corsica, Sardinia and surrounding islets. It is closely related to Podarcis lilfordi and Podarcis pityusensis from the Balearics. For Podarcis tiliguerta, 10 subspecies have been described for satellite islets of Sardinia although these are probably not valid. The populations from Corsica and Sardinia so far have been referred to the nominate subspecies. Anyhow, genetic analysis has revealed that the lizards from Corsica and Sardinia are two different species. As Podarcis tiliguerta has initially been described for Sardinia, the lizards from Corsica should hence be a new taxon.

    At Podarcis tiliguerta, the green colouration of the back is continued on the tails, whereas at Podarcis siculus, which also occurs on Corsica and Sardinia, the green colouration of the back ends at the hind legs. Furthermore, Podarcis siculus is significantly bigger than Podarcis tiliguerta.

  • Corsica population, male: F / Bonifacio, 12.09.2013 - The lizards from Corsica look similar to those from Sardinia. So far, the Corsican taxon hasn’t been described. Anyhow, there seem to be some differences: Males from Sardinia frequently show bright green colours while those on Corsica show paler colourations. Furthermore, males from Sardinia frequently have a continuous light dorsolateral line whereas in Corsican males it is often interrupted into single spots. However, there are numerous exceptions.
