Ummidia spp.
I believe this is actually a Trapdoor Spider (Ctenizidae) rather than a Crevice Weaver (Filistatidae). The saddle-shaped depression found on the third pair of legs indicate it to be of the Genus Ummidia.

Very helpful!!
Brett: Thanks so much for the ID help. The description and attached photo clarifies your point perfectly! Fortunately, one of the few places where my photo was actually in focus allowed the viewing of the saddle-shaped depression on the 3rd pair of legs! Best wishes, Scott
