Tiphiidae: Tiphiinae: Epomidiopteron julii [male]
This is a very, very rare wasp!! I've never seen one -- few probably have. It matches the redescription perfectly that Harry Allen published in 1966. The very long tegulae, spot on the humeral angle of the pronotum, metallic-black wings, the spot above the disc of the pygidium, the lateral white spots on tergites I-III -- all point to E. julii.

Excellent find!!

 
That's really cool.
Thanks! It opened my eyes to a totally new family too, and now I realize that a wasp I photographed yesterday is a Myzinum species. I'll post it today.

 
Happy to help
Thanks for sharing these photos! Looking forward to the Myzinum shots. I most likely won't be able to get it to species since for most Tiphiids you need a microscope to identify them.
