Hi Yesterday I attemped to classify the pictures of Sciomyzid flies I made last year. I have a question regarding some flies I think that belong to Euthycera genus. First two pictures were shot in Palam?s, Catalonia, NE Spain in a Quercus suber wood at the beginning of June, while the last two were shot in deciduos Quercus robur wood in Monforte de Lemos, Galicia NW Spain at the end of July. I think the first two may belong to Euthycera alaris, while I am not so sure about the last two, which provisionally I have considered to belong to the same species. Since I am a freshman with Sciomyzids, I appreciate any help to determine them. Regards Miquel Filex attached the following image:  [45.04Kb] |

They are two different species. I think first one is indeed E. alaris. Second species could be E. cribrata, I'll need to see the frons clearly to be sure. Stephane. |

What Stephane wrote as usualy has sence, but I've never had in my hand South-West European Euthycera and I have my personal doubts about situation with this genus... So, I'm not ready to go futher than Euthycera. Nikita Nikita Vikhrev - Zool Museum of Moscow University |

Thanks a lot! This is the most frontal view that I have from the second species. Filex attached the following image:  [31.37Kb] |

After surfing a bit, I have found this picture of Euthycera cribrata (see link below). I think it matches the second species, which would corroborate Stephane's opinion. http://flickr.com/photos/9909228@N05/2198791139/ |

Miquel, Euthycera cribrata, as typical character, doesn't have any dark spot at base of its anterior orbital setae (dark spot just goes round like shown on this picture). Sorry, but I have difficulties to appreciate with your pictures, and like Nikita said, we have to be wise with this genus. Stephane. |

OK, it should be E. cribrata. Regards. Stephane. |
