I can't be 100% sure but I think you have one of my old buddies there. Segestria florentina or Tube web spider. I don't now how to cross thread you to my original thread but it was posted on 5/3/06 using its scientific name. It is very aggressive and originally from the med.Boddie put a good link in for me then too so you could compare and judge for yourself.
Hope that helps. ww
