Hi, I wonder if this belongs to Sciomyzidae at all? From very old forest, Loviisa, Southern Finland today.

one for nikita. ;)

Yes, maybe he can help :)

I think it is pinned Dryomyza,

So that's why it made me wonder :D I only have anilis and this is not it. And no book :( Thank You again Nikita.

Hi, any suggestions where to find the key to Dryomyzidae ? We have only four and just two of them are Dryomyza; decrepita and flaveola but without key this will stay sp. forever :(

Jari

Andrey Ozerov is working on new key. So far I know only an old one and in Russian. D. decrepita has infuscated crossveins, so it seems to be D.flaveola.

Thank You so much ! Interesting family. :)

I don't remember dryomyzids having such a row of spines on the hind femora.

There is also an old German key for this family:

Czerny, L., 1930. Dryomyzidae.? In: (E. Lindner ed.) Die Fliegen der pal?arktischen Region 5(38a): 1-8.

Hi Jan. This spines bothered and still bother me too. On the other hand a havn't any other idea instead of Dryomyzidae, antennae look very anti-Sciomyzid.
Jari, could you make a couple more images?

It is a dryomyzid, but not Pseudoneuroctena senilis rather than Dryomyza. The R1 vein should be hairy on upper surface (like in N. anilis).

This species is not common in Finland, but very widespread. Most specimens I've seen were caught in the northern half of the country.

Edit. Some sources (like Fauna Europaea) list this species as a Dryomyza.

---

Hi, it's getting interesting :) Here is an other angle. The R1 is indeed hairy on upper side. It's not visible in picture :(

Jari

And this is the habitat. Very fine old forest.

Should I add that Kahis is right?
P/D senilis is Fenoscandic species I never collected in my life :@

---

Thank You both of You. If Kahis is interested, the place is only 45 minutes East from his home :D Nice place and needs maybe a professional to vist.

Jari

---

Please do :)



I really doubt it is absent from Russia. Just look in every boreal forest stand you have there, sooner or later you'll find it :p

---

My friend and colleague Kaj Winqvist warned me about something odd going on in Dryomyzidae. As usual, he was right :)

This is definitely not Pseudoneuroctena, if the key in the Manual of Palearctic Diptera is reliable. The only dryomyzid genus with such strong setae on hind femur is Paradryomyza.

Interestingly, there seem to be no genuine Pseudoneuroctena specimens in MZH at all. I wonder if there isn't some confusion here, either in the generic characters, or in the species list...

In any case, I will hunt for the descriptions of the 4 known Paradryomyza species next, and hope we can find a finnish male with intact male genitalis (the specimen in MZH is a female).

Cheers,
Jere

---

Ok, interesting. Now I must just wait and maybe someday we will have a name for my fly :)

Gentlemen,

When looking for a picture of Dryope flaveola I came across this topic...

Kahis is right :P. This is a Paradryomyza!

P. spinigera; reported recently form Sweden and Norway but not from Finland as far as I can find.
