With those wings it looks like it should be Tephritoidea. It is not Platystomatidae due to the subcostal break. It is not any of the four species of Australian Ulidiidae. It is none of the common subfamilies of Tephritidae because the subcosta is not bent strongly at the distal end. Pyrgotidae are usually weird-looking. There is one species of Piophilidae. I do not know what it looks like. |

Hi John. 1. Australian Piophilosoma (=Thyreophora) antipodum Osten Sacken, 1881 looks quite different: https://www.gbif.org/occurrence/4130228505 2. For me this fly has some Calyptrate jizz, because of t2 with 2 pd and 1ad setae. And frons looks like that of Fanniidae. One more unusual character is closely approximated crossveins r-m and m-cu, like in Carnidae. 3. I changed title to attract Tephritoidea expert. Let's wait for their opinion(s).

I had the same observation about the frons. |

Alas, Australian Fanniidae are well revised by Pont (1973). There isn't such fly...

Pont has several publications on Australian Muscidae. None of the species in Dichaetomyia or Muscinae look like this. Other papers are paywalled. |

Coming back to this enigmatic fly. This time from the very South of Australia, from Morwell National Park (Victoria). This time we can see 1 ad and 2 pd on t2; at least 1 strong ad on t3. This fly makes me sleepless! Nikita Vikhrev attached the following image:  [85.19Kb] Nikita Vikhrev - Zool Museum of Moscow University |
