Seen 18 july 2016 on leaves of maple regrowth in dry area (N.P Hoge Veluwe) in the Netherlands. Azelinii? Any help with finding ID much appreciated. Jan Wind attached the following image:  [14.21Kb] Edited by Jan Wind on 23-07-2016 22:00 |

The modified fore femur makes it Hydrotaea. |

with Gregor. F et all (2002) Muscidae of Central Europe I have arrived at Hydrotaea cyrtoneurina as halters black, wings clear, eyes densely haired, mid tibia no AD, parafacial widt about same as width flagellomere, hind femur no ventral spine, and chaetotoxy on hind tibia and mid tibia as described for H. cyrtoneurina ...unless there is a related Hydrotaea species for this part of Europe which not occurs in Central Europe and which also fits the description. Is my conclusion correct?? see image hind leg Jan Wind attached the following image:  [29.2Kb] Edited by Jan Wind on 22-07-2016 18:23 |

If you have the specimen it would be useful to know Number of pre ac setae? Any white grey dusted vittae on scutum? Number of av, ad and pv on tibia 3? I think an ID will then be easier Edited by oceanlis2000 on 26-07-2016 14:36 Dr Elisabeth A. Harris @FloraConsUK |

Thank you for your kind attention. There are 2 pair of pre-sutural AC; Dusting on scutum as seen from behind consists of two parallel stripes bordered bij the row of DC, mainly visible pre-sutural and fading out in post sutural part. Also slight dusting on notopleuron and posterial part of humerus. On hind tibia I see 4 AV (on distal half), 2 AD, and 5 PV and 3+ smaller thinner hairs. |

There should be 6 or more av setae on tibia 3 for cyrtoneurina (+others) if yes can you give me a photo of the prescutum (dorsal view) and check that there are no ad setae on tibia 2, both sides and if small Dr Elisabeth A. Harris @FloraConsUK |

I will show a picture of tibia 3. I see now clearly 6 AV. I had confused two in the basal half as no AV as they are more ventral directed but I see now that the inplant is at AV.

Thank you for your continued attention. Do you mean by p seta only p by excluding pv and pd or all p seta including pv, p and pd? |
