Plesiomorphies of Proepeorus. Unlike Epeorus/fg4, small median titillators [see Pentamerotarsata (5)] are present. Unlike Belovius/g1, tergalii II–VII have anal rib on anal margin. Unlike Iron/fg1, tergalius I [see Epeorus/fg2 (1)] is widened not so strongly, tergalii II–VII are long, and tergalius VII usually without longitudinal fold, only with smooth longitudinal concavity, which is not enough to allow tergalius to turn under abdomen (among the species examined, only dispar [Iron] has distinct longitudinal fold). |
Size. Fore wing length 12–15 mm.
Distribution. Eastern Palaearctic and Nearctic.
