H. confinis is definitely listed for Berlin.

One thing: I have no idea what is the radial node?
I'm assuming you mean the base of r5 (I get this expression from Tschorsnig)
I've shown the base of r5 plus the "node at the junction of humeral crossvein and vein Sc" (I get this expression from Rognes). I have never seen "radial node" in a drawing of a wing.

Hopefully, one of these areas in my photo is the radial node (I guess the R vein means radial, thus the node is what I call 'the base of r5".) Sorry for my lack of understanding here.

I will post a photo of the areas with setae. be right back ...
