I have found several times this kind of arthropod unde rthe bark of plane trees (Platanus sp.) in northern Spain.

I have no idea which it may be. I have thought of some kind of Myriapod - some kind of Polyxenida or something akin - but I have discarded it. So I am a bit puzzled.

Any help to identify it?

Thank you veru much in advance.
