I need identification

[hcarlton]

I don't post often in this section, but I have something that I could use help in ID'ing.
I found this guy running through my greenhouse inside a few days ago, ridiculously quick mover and I only managed to catch him after he ran into the space inside a cardboard box. I squished him because I couldn't get a hold of him any other way, but not hard enough to ruin what he looked like. I've never seen a spider like this before, any ideas?

I take it no one here has any clue what this thing might be?

Looks like it might be something in the ground spider/sow bug spider family (Dysdera). I've never personally seen this particular one but, it has some characteristics of this family. Maybe Mach will chime in with a more definitive answer for you.

That does appear to be it, though what he was doing running around my house is still in question..... from what I can find the records for that species are either further north or more to the eastern US than here, and the ones that occurs in the Rockies looks entirely different....
