. The studied population located in the municipality San Marco d’Alunzio comprises approximately 1000 mature individuals and covers an area of roughly 5000 square meters. Given that the habitat, steep and rugged, is represented in the territory on several hectares, it is possible that the mountain complex could potentially harbour additional subpopulations of this species.
The locality where the species was found is geologically linked to the carbonate complex of the Rocche del Crasto. It occurs in the lower part of the Tyrrhenian side of the Nebrodi Mountains, in the territory of S. Marco d’Alunzio, at elevations between 250 and
a.s.l. above the Vallone Platanà, within the subunit “Lower Nebrodi” as recognized by
