Moved
Moved from Wall spiders. These are all the same population. They are around the inside of the door where I work, and when I want a break I sometimes shoot them. Frass away...

Looks good to me -- having only Kaston's book handy. For the species annulipes (aka navus) he writes: "the carapace is pale yellow with a marginal black line and dark spots and darker areas in front of and behind the eyes," which seems rather close to what you have. The BG says there are seven species in the Nearctic, but doesn't list them.

Do you have a close-up of metatarsus IV?

Yes, you are quite right (same goes for my camera).

It's not important; Kaston mentions that the calamistrum "has a double row of bristles and extends about half the length of metatarsus IV", and I was just wondering if one can oberve that.
