I find these in forests in Oregon, western half, though they're probably on the eastern half as well. They live under pieces of wood and bark, and have a small web across the ground. Mine will eat crickets, but I think they eat carpenter ants, termites, and maybe pillbugs/sowbugs. It seems about an inch long, red on the thorax and legs, and dark grey and slightly hairy on the abdomen. The closest to this spider I've found is sowbug killers, and they're in my backyard but they're smaller then this spider and also are a light tan on a hairless abdomen, with lighter colored legs. The fangs also seem different shapes but I'm not sure about that.
