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 Edited by Fred Fly on 19-01-2019 17:33 |

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. |

It looks like members of the genus Prosopantrum

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. pls see also: https://diptera.i...d_id=75133 dr. A. J.

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!
