a water scorpion-like, but it isn't. - Mastigoproctus tohono
Phoenix, Maricopa County, Arizona, USA
December 29, 2012
Size: height 4.5cm, width 2cm
found it under my washbowl, hiding in piles of stuff. my sister said it's a water scorpion because it looks like it, but after i put it into the water for 30 mins, it's dead, so i assumed it's not a water scorpion. maybe anyone knows?
thanks

Thank you !
Thanks to Gordon and John for answering.
oh so its a vinegaroon. too bad it's already died and knowing it's uncommon.
i have seen them like 3 times in my house, but this is the first time i'm able to catch it, since they run pretty fast.
and sorry forgot to put the location, i will edit this post soon.
many thanks for your time and answer!

 
was this really found in Phoenix?
I grew up in Phoenix; I know they are in the mountains in southeast AZ but was unaware if they were down in the deserts. Or was it found in the foothills on the outskirts of the city? curious to know.

 
The locality puzzles me a bit
The locality puzzles me a bit as well. Although I suspect in the drier desert regions they only very rarely come above ground.

 
Like Blaine
I have only seen them in SE Arizona, but not in drier desert regions: they prefere the oak grasslands of Huachucas and Chiricahuas to the lower Sonoran Desert. I know that may sound like a small difference in moisture to easterners but it is quite huge to us (:
I have had reports of Tailless Whip Scorpions (not vinagaroons)from the Phoenix area as well so I'm getting really curious.

 
tailless whip scorpions
yes, the tailless ones are in Phoenix; I have seen specimens from South Mountain (where I grew up) so the amblypygids are known from the Phoenix area.

This is a "vinegaroon" minus
This is a "vinegaroon" minus its whip like tail appendage. Shame it died as they are not commonly found. Location of the find would be nice to know.

Location
We need to know exactly where the bug was found, IDs vary based on region so location is very important.

 
Vinegaroon
New member her, I have (2)specimens, one 3" in length, another 2.5".
Both, found by me, large one in Orlando, Florida,1975-the second, Fort Christmas, Florida, 1980.my Dad was an entomologist, owned a pest control company in the 70's-took the first specimen to University of Florida(now UCF)they could not identify it at the time.
Thought it was cleverly put together with different insects.
The second specimen, was found, alive, by my foot while helping a friend tear down an old livestock stall-we both recognized it as " the bug I had", so we dropped it in a bucket of diesel fuel, which, preserved it perfectly-it looks menacing, like it would hurt if it got a hold of you.
Will post pictures when I get home today.
Surprisingly little information about what I thought years ago from book research was a whip tail scorpion.
