First of all, it is fuscaNa.

It was described by Shima from East Asia some 10 years ago. Later, Ziegler demonstrated the species to be present (and currently relatively common) in Europe as well. It was a manuscript name from several years, but now it has been published in ‘Diptera Stelviana part 2’, a special issue of Studia Dipterologica.
