Thread subject: Diptera.info :: Fanniidae? --> Fannia sp. (female)

Hello,

25.09.2016, Oslo/Norway, rocky fjord coast, edge of light pine tree forest. Size: 5 -7 mm, estimated.

In spite of the prominent underside of the abdomen, both in pattern and color, I could find no match – most images on the web are dorsal/lateral views anyway.
In another forum it was suggested that the fly might belong to the genus Fannia. . .is that confirmable?

Any help of identification would be very much appreciated.

Best regards
Dirk

I can confirm Fannia sp.

Thank you very much Stephane!

I was inwardly hoping that the prominent feature of the ventral abdomen would make it possible to get down to the species.

A search in Fauna Europae listed 45 Fannia-species for Norway. I did the pain work to scan thoroughly through all the pics I could get up for them via Google images.

It possibly boiles down to Fannia sociella (female).
There is a pic with a quite similar habitus in BOLDSYSTEMS (I am not sure if I am allowed here to link directly. . .)

What do you think?

Best regards
Dirk

There is pv seta on t2, so it is not F. sociella, most probably F. polychaeta

Nikita, thank you very much for your input!

Does that qualify for a Fannia cf. polychaeta?

Best regards
Dirk
