On Karpathos it has a very restricted distribution (currently found in four localities within an area of less than 10 km2, near Olympos village), whilst on Rhodes it appears to be more widespread.

Recent evidence based on complete mitogenome sequencing showed that individuals from Karpathos and Rhodos form a well-supported monophyletic group with very low genetic distance between them, thus placing the Rhodos population to P. cerigensis and not to P. bedriagae.

The species may be vulnerable to climate change, although the effects are not fully understood at a local level at present.

A further potential threat is the intensive collection for scientific and research purposes exacerbated by the limited and localised distribution of this species, although there have not been any recorded incidences of this yet.

Regarding the Rhodes subpopulation, further research is needed in order determine the specific threats to the species.
