A medium-sized, brown Winnertzia with long antennae, long wings, and setose anepimeron. Male genitalic characters specific to this species are as follows ( Jaschhof & Jaschhof 2013 : fig. 46A). Of the gonocoxal synsclerite, the ventral emargination is perfectly U-shaped and sclerotized basally, and the ventrobasal portion, which is considerably extended medially, is devoid of setae. The gonostylus, which is small in relation to the gonocoxa, is twice as long as broad, somewhat convex medially, and equipped with a long, narrow pectinate claw. The ninth tergite has a wide, shallow indentation posteriorly, which is flanked by a pair of densely microtrichose inner lobes. The aedeagal apodeme is usually slightly broadened beyond the solid basal portion, the latter being long and mostly poorly sclerotized. The knobs on the aedeagal bulge, which are few in number and far apart from each other, are in most of our specimens barely visible. Distribution in Sweden . All our specimens, 10 in total, come from the southern half of the country (Öland and Uppland). Material studied. Specimen listed by Jaschhof & Jaschhof (2013) and as follows.
