Anthomyiidae or possibly Muscidae. |

John, don't you even consider my version? Look at the wing vein. |

Sorry, I misread the wing veins. I was wrong. |

I saw this post in the morning and I tried to key it. I agree with Angioneura but I have no experience with Angioneura. I've never seen one before. I will try to key it when I have some free time. The photos are very nice, so maybe it is possible to name a species. I will try to read the keys tonight but I still have some work to do.

Angioneura acerba seems to be correct. However, I base this opinion entirely on the scutellum because the arista are difficult to judge in these photos. I think that I see small hairs in the upper part of the arista but i cannot be certain of this feature. According to Dr. Rognes, the apical scutellar bristles will be less-than-half the length of the adjacent bristles or half the length. The apical scutellar bristles in these photos are less-than-half the length. Thus, we can eliminate Angioneura cyrtoneurina because the apical bristles of Angioneura cyrtoneurina are half the length or grater and usually greater than half the length. I do not know if there are other Angioneura in Russia. If you only have acerba and cyrtoneurina, then this should be acerba. However, can we be certain that the apical bristles are not broken? we would need to see the arista to help or genitalia to be 100% certain. I will suggest Angioneura cf acerba because we cannot see genitalia or even microscopic evidence. John and Nini. Naturalists not experts. |

Thank you for the thorough answer. Unfortunately, a more detailed picture of arista was not found. If only I knew what to shoot... Regards Vladimir. |
