After trying several keys and arriving at
Brachystoma I found out that you already posted another thread recently and got the same answer (
https://diptera.i...d_id=82940). So this should probably be
Brachystoma vesiculosum, at least there is no other choice according to the Fauna Europaea.

Fauna Europaea only mentions two species of
Brachystoma,
B. vesiculosum and
B. obscuripes. According to Loew's original description te legs of
obscuripes should be entirely dark, except for, sometimes, the mid coxae. Frey (1956; Die Fliegen) lists
obscuripes as synonym of
vesiculosum without any comment. He also describes another species from Japan,
B. pleurale, which is certainly different from the species pictured above. So,
B. vesiculosum seems a safe identification.
