Unknown Robber Fly

Dear Mary,
This is a predatory Robber Fly in the family Asilidae, and we thought it would be much easier to provide you with a species identification, but we are still uncertain regarding its identity.  It reminds us very much of  
Microstylum morosum which is pictured on BugGuide, but that species is only reported as far east as Missouri on BugGuide.  We will continue to research this matter.  How large was this individual?

Eric Eaton responds after we ask his input.
I got nothin’, sorry.  I would agree with your initial diagnosis, though.  I wonder if there is more to the story?
