This fly was on wet dung, Punta Arenas, Chile. The date was 18 December 2018.

Scathophagidae? Scathopaha sp.?

No dung fly (Scathophagidae) and no lesser dung fly (Sphaeroceridae). At least first of two frontorbitals seems to curve outside and lots of dorsocentral bristles present. I would suggest Heleomyzidae.
Regards
Fred

Scathophagidae are mostly arctic. Three species are known from high altitudes in South America.

Nikita, the presence of extrem large orbitals are not corresponding with Helcomyzidae.

Hi all,

If this would be from the Palaearctic I'd suggest Prosopantrum flavifrons. Certainly because Punta arenas is at the coast. Here in North-West Europe an alien species from the Neotropics.
If anyone knows if there is any literature on Neotropic Heleomyzidae/Prosopantrum… I'd like to have a key to and original descriptions of Neotropic Prosopantrum.

Kind regards,

Ectemnius

It's not P. flavifrons. More species are described... See: Malloch. 1934. Acalyptrata (concluded), pp. 177-233. Diptera of Patagonia and South Chile, Part
VI, Fasc. 45.

I think it is Malloch (1933): Diptera of Patagonia and South Chile Part VI. Fascicle 4.- Acalyptrata (Heleomyzidae, Trypetidae, Sciomyzidae, Sapromyzidae, etc.): 177-389.
Prosopantrum covers page 199-208. 10 species included in a key and described.

Thank-you gentlemen. How amazing to see a fly on dung in the woods in Chile and a few weeks later have its ID, collaborated on by experts from Poland, Germany, Russia, Massachusetts, and the Netherlands. Cheers!

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
