Hi, I spotted this fly the 17th of April in Uppsala, central Sweden. I did not manage to catch it but hopefully the species can be determined. I think Bothria frontosa looks mpst similiar but maybe it can't be separated from Bothria alpina. Is it one of these species or maybe something else?

It is a male with borad vertex and the abdominal pattern is characteristic.
