That's it
One of the best photographs of Pachodynerus nasidens on BG so far. Males seem to be more difficult to spot than females, since they are still missing.

Male?
It would seem to me that this IS a male. Remember, Pachodynerus don't have the hooked antennae typical of other eumenines (the flagellum has only ten segments). Looking at the abdomen there appear to be seven terga.

OOPS! You're quite right
There are seven terga, hence a male. Of course, these "shortened" antennae make sexual dimorphism much less apparent than in most Eumenine genera.
