UGH, the commonly collected Ataenius are all a pain. Someday I should re-write and fully illustrate the key to US species. Based on what I can see, I'd lean toward Ataenius spretulus.

UGH-UGH. Then again it could be At. strigatus. Look at the posterior surface of the profemur. IF it is coarsely punctate it is At. strigatus. If it is At. spretulus, it should be finely punctate (if at all) and shinning. Their 'typical' pronotal punctation patterns differ also. The one imaged has sparse coarse punctures like At. spretulus, but they are more regularly spaced like At. strigatus. Being able to confidently identify 80% of your Ataenius is really good. There are lots of specimens (like this one) I have difficulty with. Sometimes Ataeninus sp. 'strigatus species group' is the best we can do!
