Hi, this is a Porcellionides. It doesn't quite look like the P. pruinosus that I know from various parts of Europe and on Crimea there may be some other species that I have never seen. Certainly Porcellionides rectifrons is present, but I think it would be prudent to also take P. approximatus and maybe P. pica or even P. sexfasciatius(?) into account.
At the moment I can't do better than Porcellionides sp. - will have a look what I can find about the other species, but it may take a while.

Cheers, Arp
