Apparently there still isn't *enough* detail, though. I've been referring to the ID keys given by Sigurd Nelson ("A Systematic Study of Michigan Pseudoscorpionida (Arachnida)", The American Midland Naturalist, April 1975, Vol. 93, No. 2, pp. 257-301). Identification down to species requires the ability to look at the claws closely enough to count setae and distinguish the venom glands, which my claw closeup isn't *quite* good enough for.

With the detail that can be seen, and the note that Chelifer cancroides is a widespread species that is the one most commonly found in houses, I'd be reasonably confident that that's what it is.
