I found this spider in my house and was hoping to identify it. I did not kill the spider. As much info as possible would be appreciated for curiousity sake.

Thanks for the info everyone! This has been my first visit to this site and I am very impressed. I do have some black widows around in my garage and have found them in my lawn furniture. It was easy to identify the females of course, but I was not familiar with the male.
Thanks again

Looks like
a male Widow. One of the experts here may know which species. See

I agree.
This is most likely a male of the southern black widow, Latrodectus mactans. The swollen pedipalps (mouthparts that look like little boxing gloves here) help distinguish this as an adult male, as opposed to a juvenile female.

Northern vs Southern
If Michael's is a Southern, does that make Troy's image a Northern?
There are about 20 images of Widows in the guide with Troy's ID'd only to Genus. Can they be ID'd to species? Can any be separated out simply by range? If you or Jeff comment on them with species ID, we can move them

Eric is right.
L. variolus does not occur in St. Lucie County
