Moscow, park, 27 june, 10mm. Scutellar apical setas crossed, arista short plumose, no setas on R, only 3setas on R4+5 base. I don't think it is Thellaria. Nikita Vikhrev attached the following image: ![]() [70.01Kb] Nikita Vikhrev - Zool Museum of Moscow University |

My first guess, based on the generally shiny black body colour and the white dusted postpronotal lobes with 2 bristles, was Leiophora innoxia. I have tried to key it through but there are some important areas that are not clear - such "how far back is the excavation in T1+2?" and "are the apical scutellar bristles crossed near their midpoint - or not crossed/only crossed at their tips?". Also, clarifying the colour of tha palps would be useful. ![]() |

Hi Chris. 1. Excuse me, what is T1+2? 2. Apical scutellar bristles crossed even good before midpoint. 3. Palps - reddish brown. Nikita Nikita Vikhrev - Zool Museum of Moscow University |

Hi Nikita Sorry, it's a common abbreviation for Tergites 1+2, the 2 fused tergites that make up the first visible segment on the abdomen, just behind the scutellum. In most species there is a 'dent' or 'depression' in this tergite and one of the keying features is to note if the depression reaches the posterior margin of T1+2 ![]() Hmm, with a fly of 10mm; apical scutellars that are crossed so much; and light palps (not black) it might not be Leiophora after all. ![]() Edited by ChrisR on 28-06-2006 10:19 |

Hi Chris. I'll try to answer. Nikita P.S. I thought, that the best way to ID it, has to be checking all few Tachinidae with plumose arista. But it isn't easy to find the cases with plumose arista among a lot of Tachinidae, alas. Nikita Vikhrev - Zool Museum of Moscow University |

Sorry, I missed the 'short plumose' bit (I must learn to read!) ![]() |

Excuse me, what is T1+2? I put an explanation in the glossary on seeing your question Nikita.If you do not ask you will never know. But those fused tergites are a real problem. Aren't they? |
