 Is this Gymnosoma dolycoridis? Or the more common G. nudifrons?
About 6-7 mm.
Near Stockholm, Sweden, Yesterday.

 Parafrontalia has a narrow stripe all the way down to the antenna. Nudifrons?

 We need to see the scutum and scutellum.


Thanks

 That´s intresting. G. rotundatum is not found in Sweden earlier?

 This Gymnosoma was nudifrons after all. I send the fly to Zeegers who had kindness to look closer at it. This is his answer:

" I had a second good look.
As said, based on the frons, your specimen is intermediate.

So we have to try other features. These are only 90 % reliable. But if
you combine these (totally dark scutellum, darkened wing, form of
genitalia), all point towards nudifrons.
SO, I am inclined to think that this is an aberrant female of G. nudifrons.
In any case, it cannot be considered a definitive (or probable)
rotundatum. So, false alarm, after all, but it is not weird that I was
misled by the pictures !"

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
