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.

You may live in a place where the ranges of several species overlap or your spider may not look quite right for the location. Bugguide.net has great graphics for telling species apart. On our site you can tap your state name to see what has been identified previously. The World Spider Catalog has thorough references for genera and species. Please let us know if you find a good answer. Meanwhile, someone… Read more »
