Thread subject: Diptera.info :: Fannia sp. - but which?

Hello

On July 1 I caught three individuals of this species in deciduous forest near Copenhagen.

Body length ranging from 4.5 to 6.0 mm.

I can't quite figure out what species they belong to. t2 resembles that of F. armata, but the genitalia are very different being absolutely minute. The surstyli are narrow, short and weakly S-shaped and glossy black, the cercal plate very inconspicuous.

I'm using Rozkozný, Gregor, Pont (1997) but I can't find any satisfying match for the genitalia in their drawings - undoubtedly my fault ;)

First a view of the legs!

It is Fannia scalaris (Fabr.)

Thanks, Nikita.

Well. of course it is! I knew I had seen it before but I must have overlooked the hook-like setae on cx2.
