I took this pic around 9pm recently in Mesa, AZ in my driveway. This critter was about 4” across, has six legs and two very long antennae that extend about an inch or so past it’s leg width.
At first I thought it was a vinegaroon, or whip scorpion, but after seeing those on Google, I don’t think so…

Tailless Whipscorpion

Dear P. Aten,
There are two different orders of Whipscorpions.  The Vinegaroons or Whipscorpions are in the order Uropogi which you can find on BugGuide.  The members, though similar, are quite different from your specimen.
  You have submitted a photograph of a Tailless Whipscorpion in the order Amblypygi, which is also represented on BugGuide.  Both orders are without venom and they are consequently harmless to people.
