Where might i find info on spiders of the southern california deserts with pictures at?

the spider in question looks quite alot like a black widow with out the red hourglass spot on the belly. It is totally all a shiny black color it has 4long legs on either side of the body, with what looks like 2 walrus tusks on the front of the face. It is aprox. 1/2inch in length. I reside in the high desert of Southern California(Yucca Valley) and i found this creature lurking on the wall by my doorbell at the front door. My door faces the east. I found it around 2pmm pst. If this helps with my question.i would like to get info and pictures if possible. It is not a black widow.

Here is site that has desert spiders information, and there is a spider that is a "false" black widow, looks just like a black widow without the hourglass shape on the abdo, and it is found in the So. California area, so this may be your spider.
