This is Pelegrina proterva, or what I call the White-lined Jumping Spider. Most spiders don't have common names, so I just make one up. Notice the U shaped white band around the abdomen. It breaks up into smaller spots near the rear. Other jumpers may have a similar pattern, so what do I use to separate it? There is a solid white band on the front of the head.
This is a male. The female has two brown stripes on the abdomen, and lacks any white spotting. While us men tend to sport a mustache from time to time, it's the female here who has a white mustache on her face.
These spiders make a tunnel underground, and hide the top with a manhole cover. They peek out and pounce on any prey walking by, then pull it down, and fold the door closed. If you ever get a chance to see them do this live, or watch a film, they are neatest things.
I'd like once again to thank the Ohio Spiderman, Richard Bradley for his help in verifying and/or correcting my identifications. Dr. Bradley doesn't just tell me what they are, but fills me with loads of information. I appreciate his going above and beyond in helping us amateurs.
