The distribution range of Algyroides fitzingeri is restricted to Corsica and Sardinia. It's a diminutive lizard with strongly keeled scales like a little fir cone.
In particular on Corsica, the species was formerly supposed to be rare but it seems that it just had been frequently overlooked – due to its small size and its secretive behaviour.
It prefers rather humid (micro-)habitats with enough shade and dense vegetation.
Within its distribution area, it cannot be confused with other species:
Its closest relative is Algyroides marchi in Spain.
