Hi, Someone gave me this Tabanidae from the Alps. Infortunatly I don't have the altitude. Close to a torrent. To what I see on different angles, there is nolines on the eyes. No hairs on the eyes. I can't find any relevant identification. Do you have any idea? Sorry for the poor condition of the specimen. Molines en Queyras, 31/07/2012    |

I would never be 100% sure about eye bands looking at a dry specimen but absence of the stripes+brownish sides of the abdominal tergites suggest Tabanus miki...
Cheers, Sergiy |

It is very tricky, not to say impossible, to judge the number of bands from pictures from dead animals..... If the specimen is still available, I'd like to see an lateral closeup of the head, showing the occiput. Thanks Theo |

sorry for the long delay, I was quite taken last week. Here is the close up (no easy to do, I guess you are looking at the pilosity) I noticed for the eyes bands: I have a large number of T bromius, and I can see the eye band on less than half of them!  I can make other pictures. |

Dried specimens are losting eyebands very often. You can see them after refreshing, e.g., in water... |

Really efficient technique! 3 bands then, that lead me to T tergestinus |

I understand, but no, no way. No it has three bands, my gut feeling is proven right: it is a female Hybomitra, which somehow lost the hairs on the eye. Theo |

Zut! Didn't see that coming when I first try to ID it! I'll try with this genus! By the way, congratulation for the Tabanidae dutch key! Really really nice to have all those drawings and pictures, that are often so missing in other keys. A bit sad that it isn't in English, but online translator give some understantable translation (if you more or less know what to look at) |

Not so easy. I balance between H expollicata or H acuminata. But I guess I am wrong on something, those two species appaer to be saline species, not sure we can find thi in the middle of the Alps. The red extend until half the third tergite. |

As you said, can ‘t be. Moreover, the stem of the haltere is dark. It is H. momtana. Theo |
