Aptostichus species undetermined - Aptostichus simus

Aptostichus species undetermined - Aptostichus simus
Huntington Beach @Bolsa Chica Ecological Reserve, Orange County, California, USA
October 4, 2013
Size: 1-1 1/2 inches
Can anyone help me ID this spider? I found this pale reddish spider as it was dashing across the sand on the ground near the water at the Bolsa Chica Eco.Reserve. It was fairly large approx. 1&1/2 inch or so. I was only able to get one photo before it dashed off.

Moved from Aptostichus.

I bet that this is A. simus,
I bet that this is A. simus, the ‘Southern Coastal Dune Trapdoor Spider’, known from Huntington Beach...

Matches well with...
Seems to match up well with the male A. simus

I photographed in Santa Barbara County.

Moved from Spiders. Wow, this genus went from 5 species listed on our info page to 40 species. I know very little about these and since there are so many of them I think it's best we leave this at genus level for now. I'll talk to Lenny and see if there is some range info or some other info that can help us be sure of his ID.

Aptostichus species unknown
I had further conversation with Mr.Vincent, alerting him to the fact the documentation he provided me said the species killerdana was thought to be extinct (even though the location was appropriate). He said it would be better, in that case, to leave the ID at simply Mygalomorph.

I'm comfortable with it being here for now
We've had to votes for that genus so I think the genus might be correct. Can you tell me what documentation Lenny provided you?

Aptostichus species undetermined
Here is the link he gave me.

I'll try to review that tomorrow morning.

Also above I meant 'two' votes!

Moved from ID Request.

I'm not familiar with most mygalomorphs yet, but I wonder if this might be a male Aptostichus. Let's see what others think.

mystery aptostichus
I think I'll only go so far as to say it is a Mygalomorph of unknown species, since it would take an expert examining the actual spider to go further with any confidence.
