Dear Andrzej,
Many thanks! We used that key and made a new picture of the Surstyli (picture aded)
That makes it Suillia simillis.

Hello Jan Willem,

You mean this one: https://diptera.info/forum/viewthread.php?forum_id=5&thread_id=115828
That stays Suillia laevifrons, based on the male genetalia.
Kind regards,
Sandra

Jan Willem, it was a bit confusing because Sandra and I used a British key where similis is not included. As Sandra writes and dr. Woznica told in the other thread the other specimen looks very good for laevifrons. Look at the different shape of the surstylus.
We now use the hungarian key :-)

Hello Sandra and Arnold,

That was the specimen I was referring to. And the genitalia of both specimens are indeed different.
Also Andrzej is a real specialist Smile.

Nice to have a additional species for the Netherlands.
