There are quite few scathophagids with 3 bristles on sternopleuron, so if it is a Scathophagid it's probably Orthochaeta |

Not a Scathophagid, I'm afraid, but a female Pegomya (Anthomyiidae). Note the larger lower calypter in photo 1, which limits it to a few species of Pegomya, but at present I am not certain, may come back on this |

With all my respect to Michael, I think that in this case I can give a species name: P. testacea. Reasons: 1. Females of P. testacea are typical for late autumn forest at my experience. 2. Let us follow Michael's own key: pra strong; t3 with only 1 av lower calypter large (photo 1); interfrontal present; palpus entirely yellow; presutural acrostichal rows widely separated; completely orange species; Large species.

My key is out of date, Nikita, which is why I have wirhdrawn it to write another one. You have failed to take into account another Pegomya species, namely Pegomya prisca Michelsen, 2006. This species also occurs in the Czech Republic, but is not a British species to date, so it won't occur in my key anyway. It differs from testacea in a few colour characters, and I think it is possible that the darker postpedicel in the photo indicates P. prisca female rather than testacea. As is usually the case, only a dissection of the oviscapt would provide definite ID. It is inadvisible to use colours when looking at photos in my experience, |

Thank you for this explanation, Michael. In this case, the series of "P.testacea" I collected in Moscow in October 2007 should be P. prisca Nikita Vikhrev - Zool Museum of Moscow University |
