Hello, Paul! Paul Beuk wrote: Looks like Tricholauxania praeusta Thank you! I did not think that Tricholauxania also could have those spots on the abdomen...

I am not convinced either, as markings on dm-cu crossvien, and tips of the wings are not visable. Supect thid is Sapromyza sp? |

The radial vein appears to have ventral setulae, though...

Weird, Paul, but indeed especially on the second picture, but T. praeusta has no markings on the abdomen for sure. And if I look at the head I think I can see only 1 orbital bristle: S. albiceps....?

OMG, if my wife reacts like that I am in big shit! Do you agree, Paul, or not? I think your opinion is important, since you also know the Lauxaniidae well! ruud van der weele rvanderweele@gmail.com |

Why not Sapromyza (Sapromyza) sexpunctata ? http://www.dipter...p;chars=50 http://cubits.org... |

only 1 orbital is very typical for S. albiceps

Can you be sure there's only one orbital Ruud? Does S. albiceps have 6 spots? I can see this has in an extra spot showing in the first photo.

The photo of S. albiceps in the gallery doesn't look to have any spots.. http://www.dipter...to_id=1636 Besides, Juergen always has the same flies I have!

On the photo's I can see clearly only 1 orbitle. I can send you a photo of the drawing in the key of Laci Papp. Then it is quite easily seen. Do you see 6 spots? I see only 2 pair. Czerny mentions BTW only one pair of spots, Laci, for females, 2 pairs. I don't know why he separately mentions the females. ruud van der weele rvanderweele@gmail.com |

Hello, all! Thank you! Interesting discussion  . May I conclude that the majority of votes are for Sapromyza albiceps now?

I am democratic, but it is not a democratic decision. It belongs to S. albiceps or to c.f. albiceps or not at all. Problem with this kind of flies is that it is always much easier to have them under the microscope.

I lost my SQL SERVER!  Yes you are correct Ruud, I lightened the photo and there is one orbital, the 'spot' turns out to be a black bristle. blowave attached the following image:  [107.53Kb] Edited by blowave on 24-01-2012 21:28 http://cubits.org... |
