Winnertzia brevipalpata

description: Winnertzia brevipalpata Jaschhof
Diagnosis. A small, brown Winnertzia with single-segmented palpi and long, narrow wings. Male genitalic characters diagnostic of this species are as follows (Jaschhof & Jaschhof 2013: fig. 36A–B). The gonostylar apex, which is slightly swollen, bears dense, large microtrichia and a small pectinate claw. The aedeagal apodeme is gently tapered towards the apex, which is membranous and very thin (even thinner than depicted by Jaschhof & Jaschhof (2013: fig. 36B)). In undisturbed specimens, the evenly rounded tegminal apex is unusually sharply contoured, possibly as a result of sclerotization. Of the gonocoxal synsclerite, the ventral emargination is deep (usually even deeper than depicted by Jaschhof & Jaschhof (2013: fig. 36B)), V-shaped and membranous basally; and the dorsal apodemes are long and thin. The posterior edge of the ninth tergite is broad with a shallow concavity medially.
Distribution in Sweden. All the 24 males in our material come from the southern half of Sweden (Småland to Uppland, including the two large islands, Öland and Gotland), which might indicate the species’s absence from the boreal forest zone.
