Thread subject: Diptera.info :: Spilogona marginifera from Holland

The fly on these photos was tentatively identified as Spilogona spec. Can the ID be narrowed down to species level?
Medium size, I guess (but I'm bad at it!) some 7 - 8 mm. Habitat rather special, inland sand-drift (large stretches of open sand without much vegetation) with a.o. European beachgrass. Photos from last weekend.

Fantastic one, however I have no idea of what it is. :(
It is almost for sure in the Limnophorini tribe, Spilogona
though). The broad parafacialiae reminds me of Spilogona marginifera
, but it doesn't seem to be this species.
I don't know if you collect flies, but this one would be interesting !

Alas, no collected specimens...(Jorge knows) However, Joke van Erkelens lives close to the area and she promised she will try to collect some ASAP...

Almost a year later, I went to collect this fly. We (I went with Joke van Erkelens) saw only very few and managed to capture only one male. Joke identified it as, indeed, Spilogona marginifera conform Stephane's hunch. I add a photo made by Joke to show the diagnostic features on the head.

Thank you Cor and Joke for the feedback and confirmation ! This is an a very peculiar and nice Muscidae.
