Hi, I know, it's just based on a few images I saw and most of all Nikita's input. That's all I can do. 6-7 mm, august, The Netherlands, at night. Andr Andre Jas attached the following image:  [88.83Kb] Edited by Andre Jas on 31-10-2006 14:16 |

Hi Andre. I think that Lauxaniidae family is correct. But Neogriphoneura, as far as I know is Nearctic genus. In Palearctic it may be Lyciella (it is old name). Nikita Nikita Vikhrev - Zool Museum of Moscow University |

Hi Nikita, Found more images of same species. Do they confirm Lyciella? Andr Andre Jas attached the following image:  [69.67Kb] |

Andre, I don't know this family. If you change thread's name to, for example, "Meiosimyza?", Paul will find it and reply someday. Nikita Nikita Vikhrev - Zool Museum of Moscow University |

It is for sure a lauxaniidae. This evening I will see whether I can say something more about it

Andre, the silence about your Meiosimyza may be illustrated by my Meiosimyza. Sochi region, Akhun mount, forest, 28 OKt. Yesterday Anatolia Shatalkin (at least one of the best in Lauxaniidae) told me that on first investigation my looks like new species. He commented - "late autumn, nobody collected this period..."

From Niki?`s photo`s it is soon clear what the difference is between subgenus Meiosimyza and Lyciella: THe first one has only 1 sternopl. bristle, the second has two. Given the 4 rows of ac, of which the inner ones are much longer than the other ones I think it is Lyciella rorida. I observed this species also very late in the season, but never in November. ruud van der weele rvanderweele@gmail.com |

Ruud, I thought that according to modern classification Meiosimyza IS Lyciella and that they are not subgenera but senior and junior synonym.

Always you the Cat. of Pal. Diptera. Yes, Paul, you are right. I was too lazy and used Papp Hungarian key. In it he is still using the old subgenera. In my collection I made no differentation as in the Cat. The animals of Nikita are, I did not mention, L. platycephala. BTW, you agree with the species, L.rorida, I presume. ruud van der weele rvanderweele@gmail.com |

Hi Ruud, Just to fill me in (I don't know all the abbreviations yet): [Given the 4 rows of ac] (is that anterior dorso-central seta(e)?), of which the inner ones are much longer than the other ones I think it is Lyciella rorida. So mine is Lyciella rorida, because it has 2 sternopl. bristles and 4 rows of ac? Andr? Jas |

You may find two rows of setae that are larger than the other setae on the dorsal part of the mesonotum, one on each side of the mid line. These are the dorsocentral setae (dc). Between those two rows may be any number of smaller setae (ranging from 0 to > 20) and these are the acrostichal setae (ac). Please note that these latter setae may not form distinct rows and that dc setae may be all together absent as well.

Paul, thanks for reacting. I was travelling and, thus, unable to react to Andre`s request. ruud van der weele rvanderweele@gmail.com |
