Male
Sorry, it's a male. Females have only 6 abdominal segments.

 
Thanks a million!
Matt, I have edited all of the labels and I also added another view that clearly shows his eleven flagellomeres.
Now I know why I was having trouble matching the clypeus to the females.

OK, considering the size, this wasp must be way too large for a male P. atratus.
That means that he is most likely a male P. subatratus. I will request his species page very soon. Thanks

 
Size
Not sure size is a good criteria for species identification. I have never seen subatratus but I know that males of atratus vary greatly in size. They can be tiny while others are almost as large as females. I guess it depends on the food supply they had as a larva.
