And how about Muscina? They have brown tip of scutellum, as it is visible in your photo. This is only a suggestion as I don't have a key on hand to check more closely. |

Hi Andrius. I didn't regard Muscina, because M isn't banded to R4+5, even slightly. Nikita Nikita Vikhrev - Zool Museum of Moscow University |

I'd agree that this is a Phaonia, but I'm not certain about the species. Nikita - can you check whether there are any hairs (apart from the usual two bristles) on the notopleuron? These hairs will be quite small, and you will need a microscope to see them. If the notopleuron is bare then I'd go for zugmayeriae. If there are any small hairs (probably around the posterior bristle) then I think it may be trimaculata. In Britain at least, zugmayeriae should have more than just the tip of the scutellum pale, and the humeri should also have a pale ground colour. Tony ---------- Tony Irwin |

Thank you Tony. I do know this hairs on the notopleuron. As I wrote, fly isn't collected. So, after: or absent, scutellum at least apicaly red, abdomen not yellow, 2 strong presutural ac, Zimin's key gives to possibility 1. ntpl bare, f - black - Ph. zugmayeriae 2. ntpl hairy, f-? - Ph. trimaculata, I'll compare with musem material.
