Keys as Agromyzid (Sc complete, both sc- and h- breaks in costa).

...and wing. Sorry for all the pictures --- I'm not very good at interpreting photoraphs always wishing I could grab the thing and turn it just a little bit... Steve Pelikan attached the following image:  [102.38Kb] |

The impression I have is that of a Scathophagidae.

So do I. But it is quite understandable sometimes that Scatophagids end up as acalyptrates, as the typical calyptrate characters are least pronounced in this family. |

Thank you both very much. That's a great suggestion that makes sense and that I'll follow up on immediately. I'm sure everyone understands how a fly I that can't be place is a terrible worry... so all will understand my gratitude. |

Thanks again for the help. I now think this is a Scathophagid (pedicel w/complete dorsal seam, gr. ampulla faintly present). The fly is only 4mm long which worried me until I learned that there are actually leaf mining scathophagids such as Paralleloma Becker, which this fly could be. I haven't been able to find any images of the genus on the WEB. |

Please, check for Gimnomera tarsea (Scathophagidae).
Stephane. |

Thanks! Gimnomera works well, though the fly lacks pre-acrostichal hairs called for in my key (Nearctic Diptera). Otherwise the match is very good... all the way to the dark edges on the terga. And the photo in Dr Stuart G. Ball's key to British Scathophagids looks very good except for the overall color. Perhaps a different species: we don't seem to have G. tarsea here (central U.S.A.), but there are several species here and I now have great hopes that the genus is correct. |

Oops, I didn't realize it was from USA. It is very likely another species (if not another genus).

No, I really you've got the genus right. The hairs could well be rubbed off (several bristles on scutellum are missing too) and everything else seems correct. I apologize for not marking the location! |

Seems to be Gimnomera incisurata J.R. Malloch 1920 type location is just 200 miles W of where this fly was. Thanks everyone! |
