Dear all, Here is a Tachnid question. Specimen is from central France (loire atlantique, dry habitat). Following central key, I endend on Bithia (B modesta if I try to go to species identification) But I must be wrong, has the front is much narrower than should be and arista has no hairs. So a little help to go further? I am not totaly sure it is not a Rhinophoridae, subscutellum is totally hidden (but there is no petiole on wing) Best wishes, clovis  clovis : France : La Roche-Blanche : 44522 : 06/06/2020 Altitude : 31 m - Taille : 12 mm Réf. : 279631  clovis : France : La Roche-Blanche : 44522 : 06/06/2020 Altitude : 31 m - Taille : 12 mm Réf. : 279634  clovis : France : La Roche-Blanche : 44522 : 06/06/2020 Altitude : 31 m - Taille : 12 mm Réf. : 279632 Edited by clovis on 16-04-2021 22:10 |

Such a narrow frons is acceptable for Bithia immaculata. Theo |

Sorry, I could not access my speciemens before. Many thanks for your help Theo! I ruled out B immaculata because of the abdominal line I see on this angle. But maybe it is to moderate to take account of?  clovis : France : La Roche-Blanche : 44522 : 06/06/2020 Altitude : 18 m - Taille : 12 mm Réf. : 280348 |

Yes, no imma ulata but it does looks like Bithia. I am on the road now. Check Peter Tschorsnigs key (online available in English at Chris Raper's) website. One has a hooked syncercus, yhe other has not. Theo |

Tschorsnigs'key is the "central european key"? I was unable to find another key. Using it, I'd stay on B modesta: syncercus straight, frons 0,59-0,8 wide one eye. Do you agree? Many thanks foryou help  Good travelling (possible in you country? luky you!) |

Yes, the central European one. As for Covid, it seems we have a "Dont ask, dont tell" policy... Theo |
