Desert Recluse? - Loxosceles

Desert Recluse? - Loxosceles
Borrego Springs, San Diego County, California, USA
July 23, 2011
Size: Unknown
A visitor to our park sent this image to me asking if it was a brown recluse. Since we do not have brown recluses in CA, am I correct to assume that it is a desert recluse? The eyes are right and the "fiddle" is there but fairly light.

Desert Recluse?
Is the desert recluse bite as bad as the "Brown Recluse"? I live in the high desert in Ca. and I see a lot of these and I have been miss guided when someone told me that it WAS A BROWN RECLUSE!!

Not the same, but
..little is known about the venom and bite of the lesser-known species of brown spiders. “Although there are suspected variations in virulence among the species, all Loxosceles spiders should be considered potentially capable of producing dermonecrosis to some extent.”

Moved from ID Request.

it's Loxosceles alright
try matching it to a range map for an educated guess as to which brown spider you have.

Well, the eye pattern is a match for a Recluse spider:

I am not familiar enough with the Desert Recluse to give you a positive ID, but I do have lots of experience with Brown Recluses here in Missouri---I've been bitten twice in my life. Nasty little buggers. I still have the scars.

A search of the internet shows 6 different types of Recluse spiders for California:

Arizona Recluse - Loxosceles arizonica
Baja Recluse - Loxosceles palma
Chilean Recluse - Loxosceles laeta
Desert Recluse - Loxosceles deserta
Martha's Recluse - Loxosceles martha
Russell's Recluse - Loxosceles russelli

So, it's most likely one of those. In any case, you can tell your park visitor that it is a Recluse.
