Possibly Aphonopelma spiderling?

May not be a spiderling, many SoCal sp. are dwarves.

agreed^ maybe juvenile eutylenum

That's awesome I wish I could walk out side and have a chance of finding a T on a bug hunt

If dwarf, maybe Aphonopelma paloma or Aphonopelma sp. "Pajaritos Dwarf"?

Could be hard to identify since there are so many Aphonopelma species and very few are described.

@Jeff23 Really?? I had thought that the new(ish) revision paper pretty much covered most of them.

@BobBarley Here is the link for what I downloaded to PDF and used for searches. Is it the same document you have viewed?

The most obvious entry that I could not find in a recent search was bicoloratum. Maybe it isn't an Aphonopelma any more or is spelled differently? I'm not sure. I then searched for a couple other random ones just to make sure PDF search commands were working right and something else (can't remember what came up empty as well).

I just now searched for paloma and it is in this document. The one entry I looked at showed Arizona for its location so maybe it is less likely to be the one in the picture. If that picture is a sling it could be tough to identify. Most of my really small Aphonopelma slings have colors that are full of grays and browns. I wouldn't want to try to separate them if the labels came off the containers.

@Jeff23 I believe bicoloratum is found in Mexico, and thus wouldn't be in this paper. There is a huge array of dwarf species in southern California and Arizona, but I am not really familiar with the southern species.

@BobBarley What you are saying makes sense. Maybe I misunderstood a post in a thread (or the poster was wrong) when I saw a mention of bicoloratum in Texas.

@Jeff23 Perhaps you misread, and it really said moderatum?

@BobBarley At first I thought moderatum was missing as well when I searched a few days ago after seeing a beautiful tarantula on a different gallery link.

In this case I think my problem was that I had multiple PDF's open and somehow clicked on wrong document when I did the search. I did a search for bicoloratum months ago so I don't remember much about it other than not much is available for it. I kind of gave up searching for a T in that species.
