One of the Pallopteridae, I think. I will leave this one to Jan Willem.

Hi Black, I will give it a try tonight. However I know that Andrey Ozerov has described several new species from Russia. I don't know these species. So it may be a good idea to ask Andrey Ozerov for his opinion. Jan Willem |

Hi Dima, My best guess would be Toxoneura quinquemaculata (or Palloptera quinquemaculata), but I'm not at all sure. The ovipositor should be broad, but you can only see the tip; the space below the eye should be high, but that is difficult to see. I'm looking forward to hear the opinion of Andrey Ozerov.

Jan Willem, what is the status of Palloptera in its broad sense and the situation with all the separate smaller genera?

Hi, Paul Asked: what is the status of Palloptera in its broad sense and the situation with all the separate smaller genera? In the British checklist is stated: McAlpine recognised the splitting of Palloptera into several genera, the British species being assigned to Palloptera, Temnosira Enderlein and Toxoneura Macquart. These genera were based on chaetotactic characters which did not lead to natural groups, so are not accepted here. Well I have to admit that I have my doubts about the generic devision proposed by McAlpine and therefor prefer placing the species of these genera all in the genus Palloptera (with the exeption of Eurygnathomyia bicolor), like is done in the British checklist. Apparently several dipterists think otherwise because the generic division of McAlpine is followed by many of them. I have to admit though that to form a good opinion about this I would really need to study a lot of specimens much more serious than I have done yet (which would not be a bad idea if I had the time to do so!).

Thanks. Well, it may be interesting to knwo that A. Ozerov also synonymised several of McAlpine's Piophilidae genera...

Thanks to all, I just wonder what kept me from collecting it (maybe heat), the fly was rather indolent - maybe next morning I'll examine Aegopodium umbels there. |

It is Toxoneura trimacula (Meigen), I think. |

Hi Andrey, I think you are right. At first I thought cross vein ta was also clouded, but giving it a better look I think only the vein itself is dark. In Toxoneura quinquemaculata this vein is distinctly clouded. Moreover, the specimen is too pale for quinquemaculata and the jowl (although you cannot see this very clearly in the picture) seems not to be high enough for quinquemaculata. So Dima, you can label it Toxoneura quinquemaculata. Sorry, should be: You can label it Toxoneura trimacula And Andrey, what is your opinion on the division into genera like Toxoneura, Temnosira, and Palloptera?

Is it the same one? Collected by sweeping on July o1, 2006 at approximately same location (more open place, closer to the railroad). Size 3.5-4mm. |
