Hi, this was in my net today. May 29.2009 Loviisa, Finland.

Without my key near hand I would suggest a female of the Rhamphomyia albosegmentata group, but difficult to say from the single image.

Ok, thank You Paul. That is enough, because I don't have a Rhamphomyia key :( Any suggestions where to find one ?

Well, there is the old key in Die Fliegen der paläartkischen Region, but that is at least for the names but also for (some of) the keys out-of-date. Next there is Collin's key to the British Empididae, far from complete for your region, as is Barták's key to the Czechoslovak species. Fo the albosegmentata group there also is a revision by Barták but I am not 100% certain that it is for Scandinavia, too.

A little expansion on the identity of this species: The hind femur has ventral spines. There are two groups where they can be found: the sulcata and the albosegmentata groups. On second thought it might be sulcata group as the legs have few other hairs and I think in the [i]albosegmentata[i] group the should be more setose.

---

PS: The three species of the sulcata group are in the two recent keys. IMAO, cinerascens and subcinerascens are synonymous (distribution of both species is determined by the keys the entomologists use as not key actually has given good characters to separate them and I have found no consistent differences between specimens from different parts of Europe. The other species are sulcata, sulcatella and sulcatina.

Now I had time to look this one again. We have sulcata and sulcatina in Finland. As I don't have the key, where should I look to separate these ?
