Arizona Bark, or Hairy Desert Scorpion? - Smeringurus mesaensis

Arizona Bark, or Hairy Desert Scorpion? - Smeringurus mesaensis
Lucerne Valley: 20 mi N of Big Bear Lake, 20 mi E of Victorville/Apple Valley, San Bernardino County, California, USA
August 26, 2007
Size: 2-2.5"
Mild night, some light scattered cloud cover, meaning for the California High Desert it was relatively humid. This guy/girl (?) was clinging to the stucco on the side of my garage, not straight up-and-down but rather at a perfect right angle with the ground with his left facing downward; when I looked to my left and saw this sitting exactly at eye level, I had the impression of a sideways lion waiting to pounce. Good night for hunting, too; we had the outside lights on and the ant lions, june bugs, and sphinx moths were the thickest I've seen in a few weeks.

Looks more like a Smeringurus
Looks more like a Smeringurus mesaensis, but Im not sure of their range. I dont think its a Vaejovid and the chelae look too big to be a Centruroides exilicauda/sculpturatus. Its definitely not a Hadrurus arizonensis (desert hairy), I can tell you that much.

 
Darn...
Never heard of S. mesaensis, but after google-image searching the term (and then "Gold Sand Scorpion," apparently the common name) it seems you're right. And I was really hoping I'd be able to say I've got a specimen of the only dangerous scorpion in America!
Really though the chelae are a dead giveaway. More bulbous at the base than a Bark Scorpion.
Thanks for helping out, it'll put my mother at ease that this thing isn't seriously threatening!

...actually, upon further inspection of the scorpion itself and some very specific descriptions of the physical characteristics of a few different Vaejovids, I think it's actually a Vejovoidus; the main characteristic being that the telson is rounder and slightly more bulbous, compared to a longer and narrower telson as described of Smeringurus. Still, thanks, you've been a massive help!
