Diamesa wuelkeri Serra-Tosio, 1964

( Fig. 3 A , B)

This species is endemic from the Alps ( Serra-Tosio 1964; 1968). In Italy, an adult male of this species was collected only in Viola stream in July 1985 ( Rossaro & Lencioni 2015a, b). For details of male genitalia see Fig. 3 A , B. The species can be diagnosed based on the ventro-medial lobe of inferior volsella (“appendice inférieur) that is much better developed than the much reduced dorso-lateral lobe.
