Comments & ID Thoughts
I initially thought this was a brown recluse, but after some reading I've learned that it is more likely a desert recluse or Arizona recluse, sometimes called the Arizona brown spider. There are fewer resources on identifying these other recluse species, so any help is appreciated. Found outdoors in well housing, a 2' x 2' x 3' sheet metal box surrounding a well on a concrete pad. Also found and took a pic of several molted skins inside the box.
