What kind of spider? Found in tool shed in Miami, Florida, April 18, 2015, at 2PM. It's sitting on the 1 1/2 side of a 2X4 piece of lumber, so the body is about 1/2 inch long. It is very flat. Could not find a match on any of the spider websites.


Hi, Javier:

Believe it or not, this spider is called a "flattie," in the genus Selenops , family Selenopidae.  I wrote a blog post about them awhile back:


Neat spiders, harmless, and usually nocturnal.

Thanks for sharing the nice images!

I answer insect and spider identification questions ONLY. Attach images if possible. No "what bit me?", "what do I feed this bug in captivity?", or science fair project questions please. NO TECHNICAL QUESTIONS ABOUT INSECT PHYSIOLOGY.
