Looks very interesting (thickened arista, wing venation, setae on face), but does not ring a bell (??Elodia??) Theo |

Thanks a bunch for your input, Theo!  But if it doesn't ring a bell for you, that is really bad news  Marian took some pictures of it too. I will ask her to post them in this thread just in case her shots add some information. She might have got better detail. Please, keep an eye on this thread |

Something close to Pales?

I happen to have 1 Policheta unicolor (a rare species here) and it does look very good ... it has: - the facial ridge bristles - hairy eyes - short diverging apical scutellars - lots of median dorsals on the tergites - lateroclinate parafrontals - 3 post-dc and post-acr - excavation of T1+2 not reaching the margin My only slight doubt is the colour - mine is very black but this seems to have a blue cast to it. ... so it is Policheta unicolor or something very closely related to it

Thanks a lot for the ID and the efforts you are making, Chris! And Policheta unicolor is listed as an Iberian species too! That is good news!! About the colour, when we saw the fly we described it as 'the blackish Tachinid' not bluish. I think due to light, it looks more bluish in the pictures than it really is. It was more greyish than bluish, but definitely black. I guess that if it is confirmed, Paul would like to have those pictures in the gallery |

I don't want to spoil the meal, but the praealar seta is strong, so it seems.... Theo |

I think I see a weak pre-alar in front of a strong supra-alar Steve (please excuse my poor photoshop skills and editing the above photo) sd attached the following image:  [102.93Kb] |

Jorge has told me that H. P. Tschorsnig has confirmed it is Policheta unicolor. He said: 'The lateroclinate outer orbital bristles and the erect mouth margin are typical for this species.' Thanks a lot to anyone that has taken part of the discussion about this interesting and unexpected Tachinid And of course, the pictures will be submit to the gallery soon Also found here: http://www.biodiversidadvirtual.org/insectarium/Policheta-unicolor-Fallen-1820-img280078.html http://www.biodiversidadvirtual.org/insectarium/Policheta-unicolor-Fallen-1820-img280079.html http://www.biodiversidadvirtual.org/insectarium/Policheta-unicolor-Fallen-1820-img280080.html http://www.biodiversidadvirtual.org/insectarium/Policheta-unicolor-Fallen-1820-img280832.html |
