Thank's Jorge. Are they Trixoscelididae nowdays ? In our list they belong to Heleomyzidae. Jari |

yes, Jarif. There is Trixoscelididae by itself. It was traditionally in Heleomyzidae before.

I think this species is Trixoscelis frontalis or at least that is where I have ended up with the specimens with black fore legs here in southern Finland. |

Thank's Andrzej Jari EDIT: Last summer I had some of these too and then we came to name cf. canescens. If this is canescens it would be new to Finland again. Would You like to see the specimen maybe or is the id clear from the picture ? Edited by JariF on 11-07-2009 19:24 |

At least in Hackman's Ent. Scand. revision (1970) the name canescens doesn't occur at all, and it is also absent in our draft national check list. But on the other hand it does occur in Bei-Bienko. Right now I haven't got any references to clear out the potential synonymies in Trixoscelis but I have a vague remembrance that I once tried to introduce canescens to the Finnish fauna, but without success. |

I got mail from Andrzej and there are pictures coming to help determination. Here it seems to be valid http://www.faunaeur.org/full_results.php?id=66632 Jari |

Ok, in that case it's time to congratulate!? I would be very interested in any further information how to differentiate frontalis and canescens, if they really represent two distinct species and are not synonyms like Hackman (1970) presumed. |
