Male
11 flagellomeres = ♂

 
Thanks for the ID
I had found another of this species a while back, is this picture good enough for a gender determination?
When you count flagellomeres, do you include the elongated antennomere at the base?

 
No
I don't think that the image is clear enough for me to gender it.
An easy way for you to gender any bee or wasp specimen is to check the abdomen for a stinger. = ♀
In this genus and a few others, you might look for a basitibial plate: ♀ (hind-legs)

The antennae come in three basic parts for most Hymenoptera:
1) - Base or Scape - This is the big fat part that attaches to the head.
2) - Pedical - This is a very small segment, barely visible on large specimens like this one. On smaller bees, they look like an extra flagellomere.
3) - Flagellum - F1 is very long on these guys. F2 is much shorter than F1 (this ratio is very different in other genera/species)
