Robber Fly 5 - Diogmites angustipennis

Robber Fly 5 - Diogmites angustipennis
Gloster, Gloster Arboretum, Amite County, Mississippi, USA
September 21, 2006
Size: body length 22.5 mm.
We believe this is Diogmites sp., possibly NOT just another variation of D. angustipennis! It was collected on tall grass in a small meadow surrounded by woods. Help would be appreciated.

Diogmites
Check the hairs standing up on the pronotum (I can't quite make them out in your picture), and the bristles on the sides of the first abdominal segment. If they are yellow it is angustipennis, if they are black, or mostly black, then you might have something other than angustipennis

 
Thanks Norm,
I have added a closeup of the first abdominal segment. This clearly shows the yellow bristles on the sides. Also, examination of the hairs on the pronotum revealed that these were also yellow.
I am delighted to learn how to identify Diogmites angustipennis!
