Scorpion - Uroctonus mordax
Above Magelia, Butte County, California, USA
April 19, 2008
Size: <1 inch
Found under a rock. It's also the second one I've found in the area. I have both, and I'd like to know the species so I can sex them and find out if I can keep them together.

Uroctonus mordax?
Wondering if this is Uroctonus mordax. Pretty common in even the wetter areas of Oregon and northern California....

Maybe Pseudouroctonus iviei?
Hey Eric, great guess, and you may be right. But the dorsal keels on the metasoma/tail appear to terminate with an enlarged granule or spine. Uroctonus mordax does not have this "spine" but a very similar species (in appearance only) does have these spines on the dorsal metasomal keels. That species is Pseudouroctonus iviei.
Unfortunately, the tail is out of focus.
Is it possible for B.Dyer to get us a clear shot of the tail? If it is Ps. iviei, we can add a new page to the IDs and do a write-up on it.

Unfortunately, I can't. This
Unfortunately, I can't. This specimen died(my fault) and I recently released the other, which may or may not have been the same species. I'll definitely try to get some pictures if I'm in the area again.
