Normally I can separate most Diptera to at least these two categories, but with this one I have problems. Unfortunately the image is not fine enough to count the number of antenna segments. The antennae are very long, which hints to Nematocera, the overall structure however suggests Asilidae or Empididae. Edited by Xespok on 06-10-2005 16:19 |

Unfortunately I cannot make out the wing venation because the essential part is blotted out by the darker background. Any chance it might be more clearly visible in the original image? Further, it reminds me of Trichopeza longicornis of the Empididae but I do not know if that species occurs in Japan or even related genera/species. Paul - - - - Paul Beuk on https://diptera.info |

This genus does not occur in Honshu. Based on the database the following genera should occur: Empidinae: Empis, Rhamphomyia, Hilara, Oreogeton, Clinocerinae: Trichoclinocera, Acanthoclinocera, Heleodromia, Brachystoma Hybotinae: Hybos, Syneches, Chillcottomyia, Ocydromiinae: Bicellaria, Euthyneura, Euthyneura, Leptopeza, Trichina, Tachydromiinae: Symballophthalmus, \ Hemerodromiinae: Xanthodromia, Chelifera, Dolichocephala Is this Trichopeza Clinocerinae? But I think there might be quite a few species of Empididae to be described in Japan. |

Of all these genera, the only one I do not really know is Oreogeton. Trichopeza is currently placed in the subfamily Trichopezinae and not in Oreogetoninae, though...

Paul, I forgot to mention that I have another image of this fly, which probably helps you out with the wing venation. http://xespok.net...dae?page=3 Also, could this fly not belong to Xylophagidae? I have not considered that option yet. |

Hmm, no Xylophagidae as far as I can tell, but I cannot really make a good empid of it either. I will get back to this one.

I raise this very old thread, maybe some new eyes can tell us more.

I vote Blephariceridae. (Found this old thread searching on something unrelated.) |

Yes, Blephariceridae it will be, possibly Agathon sp. Thanks for solving this old mystery.

I agree. It is a Blephariceridae! Great find. And you can see the secondary veins. |
