Vinegaroon - Mastigoproctus giganteus

Vinegaroon - Mastigoproctus giganteus
Patagonia-Sonoita Creek Preserve, Santa Cruz County, Arizona, USA
August 1, 2007
Size: 3 inches w/out tail
Can this be narrowed down?

Moved
Moved from Whipscorpions.

ID
This little beauty is Mastigoproctus giganteus.

Will, if you think this one looks like it has 'demon-genes', you should see if you can find pictures of amblypygids. I would say they are even 'less fortunate' with their looks that uropygids (where M. giganteus belong).

 
Hi Erik,
Could you add a few words indicating how you know what you know? If that constitutes experiential or academic qualifications, you could put that on your profile page. If the ID is based on comparison with other images, you could link to one or two in your reply. If it is based on working through a key, you could say where the key can be found or link to it if it's online.

What we want to avoid is unqualified (and incorrect) IDs if possible and since I know of you only from a single image posting and this comment I would like some assurance that the ID is a good one before moving it to a species page.

 
Bugguide has a few of those
here.

I didn't mean Will (sorry!)
I meant Erik.

 
In the mean time
I moved it to order page.

What in god's name?
What on Earth is this??? It's like some spider/scorpion/demon hybrid

 
It's common in the Soutwest.
The common name refers to this creature's use of acetic acid in its chemical arsenal, making its nasty encounters smell like strong vinegar.

 
Whipscorpion
I'm just wondering if I can get it to genus or species.

 
Awesome photo!
By the way this is a great photo! Cool find
