It is very quiet on this thread. I am not sure, but I have an opinion. It reminds me of Eginia ocypterata. That is a difficult fly to identify from a picture. It is difficult to assign at family level at all. It looks like a scatophagid, parasite with meral bristles as in tachinidae, but now placed in Muscidae. Therefor picture could be compared with specimens in collection. Unfortunatedly I do not have a specimen in my collection. It is rare. I found some drawings of Eginia. Hindlegs have more bristles in Eginia, but that might be a difference between male (on drawing) and female (on this picture?). Black, did you collect specimens? And where did you take the pictures?

Many thanks for your suggestion Liekele. Yes I've got one specimen, collected in the vicinity of Naro-Fominsk, Moscow region, Russia. |

Whatever the name is , it is nothing I've seen before. So please, tell us if and when you can confirm it is Eginia.

Please check for positive identification: Is it male or female? Has it hairs on ventral surface of scutellum, laterally or in the middle? Is meron with or without bristles near hind margin (before hind spiracle)? Does anal vein reach or nearly reach the wing margin? Liekele |

OK I'll try (I doubt I can see ventral surface of scutellum, though...) |

Dima The hairs on the ventral surface of Anthomyids are surprisingly easy to see with good light and even just 10x magnification - they point downwards, and tend to run round the outer edge. They are a really useful character. Susan |

Black, I hope Paul will add your beautifull pictures to the gallery. For him the difficult choice in which family it belongs: Muscidae or Eginiidae. As far as I know, it is a rare species. Regards, Liekele |

Many thanks Nikita (commissioned to solve that  ) and Liekele. Fauna Europaea places it in Muscidae/Phaoniinae/Eginiini. |

There is one important note. In Gregor at all key for "Muscidae of Central Europe" in description of Eginia "anal vein does not reach the posterior wing margin". According old Stackelberg's key "A do reach wing margin" At least this specimens fits Stackelberg description - A obviosly reach wing margin as in Anthomyiidae.

With an anal vein that runs to the wing margin, and meral bristles, this really bends the rules for Muscidae, so it's great that Black has taken these wonderful pictures. This fly would have given me quite a headache if I had tried to identify it!

I wonder, whether these images posted by me earlier might show the same species.

In your pictures the bristles on tergites are much smaller. So, I doubt it. Theo |

Antennal segments are differently shaped as well.
