Thanks, Theo

I can't find a complete list of species in Sturmiini (I suppose splitted from Goniini), here:
https://www.ncbi.nlm.nih.gov/Taxonomy/Browser/wwwtax.cgi?mode=Undef&id=179458&lvl=3&keep=1&srchmode=1&unlock
The only european genus is Sturmia and the unique species Sturmia bella...
Which other genus could this be ?

I found it more similar to Blepharippa pratensis, which was determined by you from a collected specimen at the same area:
