Good evening, I saw this fly ( lenght about 2 mm ) last week near Heerlen. The eyes were green, the flash made them red. Ben Ben Hamers attached the following image:  [40.18Kb] Edited by Ben Hamers on 27-06-2018 19:18 |

I think this is a member or the Chyromyidae. If you can provide an image with some more detail of the dorsal part of the thorax and scutellum I may be able to be more precise.

Hi Paul, Here are two other pictures, the first one is a dorsal view of the fly concerned. I saw in your Checklist of the Diptera that Chyromyidae are often found on windows. That reminded me of an older picture. Ben Ben Hamers attached the following image:  [78.72Kb] Edited by Ben Hamers on 23-05-2012 19:23 |

Well, it took me thirteen years to find a similar looking fly again, at exactly the same place, 20-06-2018, near Heerlen, NL. The blackened front tarsi are distinctive. Is it Chyromya miladae ? Ben Ben Hamers attached the following image:  [262.63Kb] Edited by Ben Hamers on 22-06-2018 08:13 |

I am inclined to say britannica (tip of fourth front tarsal segment seems to bee entirely dark rather than just the extreme corners) but if you kept it and are willing to drop it off at the muzeum in Maastricht I'd be happy to confirm it after microscopic examination.

Thanks Paul, I didn't catch the fly, it was sitting on the same power pylon as the last one. I only have a slightly better view of the front tarsi. Ben Ben Hamers attached the following image:  [117.19Kb] |

Hello Ben Hamers, Yes! Now the third new species of Chyromyidae this year for the Netherlands. Dick Belgers caught Chyromyia miladae and Gymnochiromyia inermis. Last year I was able to catch Gymnochiromyia mihalyii. Thus I am writing a paper about the Dutch Chyromyidae. This is indeed Chyromya brittanica Gibbs, 2007, a male! Very nice find and the first from anywhere outside England! Kind regards, Ectemnius Edited by Ectemnius on 22-06-2018 08:44 |

Btw, your photo of the under side of 03-08-2005 19:08 is not Chyromyidae, but Asteiidae. Asteia c.f. amoena, because vein r2+3 is very short and the white facial stripe is present. |

Hi Paul, That is very nice! How about writing a paper together? Both of our data and the photo's of Dick Belgers (he shot nice photo's of several species) and Ben Hamers should make a very nice paper. Kind regards, Ectemnius Edited by Ectemnius on 22-06-2018 09:22 |

I am all in for it. Sorting a few Malaise trap sample series results in too many additions to cope with, really, especially as they are from too many different families.

Great! And yes, I know the feeling... Malaisetraps are so exciting and yet so terrible. I will send you a mail with the final version of the Stenomicra paper at the end of July. |
