I determined this exemplar as Dixa puberula=D.sobrina. I would be very grateful if a specialist can confirm this definition. Material from Nature park near Moscow University, specimen trapped near stream running down a hill. Cranefly attached the following image:  [183.56Kb] |

How about D. submaculata?

Gonistylus is relatively broad and cylindrical, narrowing at the most apex. Gonocoxite with small apical internal projection covered with hairs. And some more small paired sclerotized structure (paramere?) is hooked, curved. |

According the key of Disney (1999) in D. puberula there is typically a small dark cloud over the angle between veins R1 and Rs, but no clouding behind the angle of Cu1 where this vein is joined by the cross vein mCu. In your specimen it seems to be exactly the opposite. Edited by Jan Willem on 01-03-2023 17:07 Jan Willem van Zuijlen |

Many thanks. I'll check it once more. I don.t know external characters well because never determined Dixidae before. |

My experience with identifying Dixidae is also very limited (I only did so once). Maybe someone with more experience can also give feedback. Jan Willem van Zuijlen |
