It is one of the rarest flies in the world. Try to guess who it

is.

I'd say it's a diopsid :) And that's where all my ideas end :D

No, it is not a diopsid. Diopsidae have eyes on stalks that are narrowed between the median part of the head and the compound eyes. It more resembles the genus Achias from the Australian region (Platystomatidae) but I know of records of something similar from Central America.
There is a south American family with broad heads (Eurychoromyidae) but I think it t is only known from four specimens of a single species and that species has not such a broad head.

Try Plagiocephalus, Ulidiidae. Really need a view of the wings

---

Hmmm Andy might be right, but there are some strange Tephretidae out there like Pelmatops from SE Asia:

Alessandra, U must give at least the zoogeographical recion this ugly beast is from. Antarctis?

My guess was first either Richardia telescopica (Richardiidae) or Plagiocephalus sp. (Ulidiidae) if from the New World, or Pelmatops, if from the Old World. What seems to be strange, the wings look patternless at all, which is not characteristical for Plagiocephalus.

And, there could be a possibility that the Plagiocephalus head was glued to a Musca domestica body. :D

BUT KNOWING THAT YOU ARE THE ONLY PERSON WHO WAS TRYING TO GET A EUCHOROMYID, i'd suspect, that IT IS!

IS IT THAT????? :| ;) AM I RIGHT?

Thanx also for the possibility to see the pix of Johann and Jef

Well, by looking at the link URL and doing a bit of Googling we arrive with a paper that has the original photos attached: "Redescription of the genus Diopsosoma Malloch (Diptera, Periscelididae)", which gives the name as "Diopsosoma primum Malloch, 1932"

Yes, Chris, I almost have reached the same result by finding out from her private pix, who is Arung, and looking for a periscelidid like this... But Paul broke the process by sending the link to Alessandra's and Wayne's paper you dug out! :|
