Can anyone id this spider? A bit larger than a quarter, black. Cephalothorax shiny but abdomen matte and fuzzy looking with a grey/silver cast. Came out of a furniture box as I was opening it. Box had some cobwebs in it so I assume it is a web building spider. Doesn't show on the picture too well but there are two distinctive white bands at the base of each leg. Just curious really.
This is a crevice weaver (family Filistatidae) in the genus Kukulcania, likely Kukulcania arizonica - http://www.flickr.com/photos/reptilist/6392620799/
They are not dangerous to humans.
