Another fly from New Mexico USA. This one was from an area where the Organ Mountains meet the Chihuahuan Desert. Is this a Robber Fly, Asilidae?
Thanks in advance for any ID help. Diptera.info is a terrific site!

Paul, you are right!

This is not a therevid, it is a robber fly genus Efferia, the males have the long genitals, easy to recognize...
nice pic!
