Diamesa insignipes Kieffer in Kieffer & Thienemann, 1908

( Fig. 6 A , B)

Illustrations of male genitalia of this species are reported by Pagast (1947), Serra-Tosio (1971b), Hansen & Cook (1976), and Makarchenko (1985). Hitherto, the species was never recorded in the Alps, whereas in Prealps the species was found in Pioverna stream only (long E 9.38, lat N 46.00). It is noteworthy that males of the Pioverna population have the inferior volsella bearing more than two robust bristles. The species inhabits also the following Apennines streams: Nure, Taro, Ceno, and Sangro ( Rossaro & Lencioni 2015a, b).
