Diamesa latitarsis (Goetghebuer, 1921)

The species is well described by Serra-Tosio (1968), with notes on the variability found on dorso-lateral and ventro-medial lobes of inferior volsella. Beside the Alps, where it is relatively common, an adult male was recorded in the Apennines (Rossaro & Lencioni 2015a, b).
