If Dolichopodidae, than Medetera, I think. The one who walk on tree bark most probably appear in amber.

Yes, it is Dolichopodidae, but I have no idea about the genus  |

Thank you Andrius and Kahis. Yesterday I had opportunity to show this fly to Igor Grichanov, his answer was - around Chrysotus. Nikita Nikita Vikhrev - Zool Museum of Moscow University |

Dear fossil lovers, I unfortunately have not a lot of experience with fossil dolichopodids, but quite some with extant species. And I can tell you with 100% certainty that this species in this piece of amber is neither a Medetera nor a Chrysotus. As far as I can see, it has the vein R4+5 and M1 diverging (like in Achalcus and Enlinia) and the hypopygium seems similar to that in Micromorphus. Cheers, Marc |

Nikita, sorry for a looong delay. I have finally named the fly: Thrypticus molestus Meunier, 1907. I hope a new generic name will soon be published for the species. BTW, R and M veins are clearly parallel on right wing.

Now it is Medeterites molestus (Meunier, 1907). See redescription and additional pictures here: Grichanov I.Ya. 2010. A new genus of Medeterinae (Diptera: Dolichopodidae) from Baltic amber (Diptera). Caucasian Entomological Bull. 6(2): 209-212. Igor Grichanov attached the following image:  [188.94Kb] Igor Grichanov |

Igor, Thank you for keeping us up to date with the nomenclature. Is your paper available online somewhere? I cannot find it through Google. Maybe it is still too new for them! I hae got much of my recent literature from the palaeoentomological library. However, it seems to be close to death, as it is progressing at about the speed of a gasteropod with a sore foot. These are really nice photographs that you have attached. Too many publications on amber palaeontology are let down by the quality of the illustrations. Best wishes, Peter |

Yes, palaeoentomological library is in standby mode. If somebody wishes pdf, please write me by email.
