Hi,

as this very small fly has only dorsally long plumouse arista, is there other possibilities than Ephydridae ? September 23. 2008 Helsinki, Finland.

I think it is Ephydridae but almost all diagnostic characters are not seen. For example face in profile or wing would be desirable for further definition (if necessary).

---

The convex face, feathery arista and what we can see of the wing venation (2 costal breaks, the to me is typical of Ephydridae.

Subfam Notiphilinae? (just guessing based on the spine on the 2nd antennal segment which can just be discerned. Hmmm... but it doesn´t look too strong, when I think about it)

Thank's,

here is an other picture of the head and wing. In fact I don't expect id with just pictures but confirmation where to go on.

Where to go on - face is with 1 row of setae (when looking anteriorly there are no strong setae on the face, some of which directed inwardly and some outwardly), ac setae on thorax are not regulated in rows, face protruding in the lower part and with depression below antennae - something like Ditrichophora or Gymnoclasiopa.

Thank's once again. Must try to use my key this evening :)

I allmost forgot this one. After I have been using the only key I have; that will say Bei-Bienko; and if we are talking abouth Ditrichophora or Gymnoclasiopa, then....

1) face on each side with two facial bristles
2) wings clear
3) genae low
4) face more or less flat
5) antenna yellow, face grey
6) distance between two bristles in first row on face less than distance between upper bristles on opposite rows

we will come to the name Gymnoclasiopa cinerella.

Am I close or far away ? :|
