Hello,

StN-Keys 2008 for Xanthogramma couplet 5 is as following:

5 Second basal cell of wing 90% or more covered in microtrichia; pale marks on tg.2 usually reaching their
greatest length on the lateral margins of the tergite, so that there they extend closest to the posterior margin of
the tergite (may only reach as close to the posterior margin as elsewhere on the tergite); pale marks on tg.3
expanded on the lateral margins of the tergite, so that there they occupy a greater part of the length of the tergite than elsewhere (or at least as great a length of the tergite as elsewhere); sternite 3 short-haired (1-4 pale marks
on the thoracic pleura) ............................................................................................... pedissequum (Harris) (male)

----- 2nd basal cell of wing 25-90% bare of microtrichia; pale marks on tg.2 cut away postero-laterally, so that
usually they are closest to the posterior margin of the tergite at some distance from its lateral margins; pale
marks on tg.3 cut away antero-laterally, so that they occupy a greater part of the length of the tergite at some
distance from its lateral margins (3-4 pale marks on the thoracic pleura) .......................... dives (Rondani) (male)

In this male specimen the characters are as following:

1) Second basal cell of wing completely covered in microtrichia (nearly 100%) --> pedissequum
2) pale marks on tg.2 cut away postero-laterally --> dives
3) pale marks on tg.3 cut away antero-laterally --> dives
4) hairs on sternite 3 shorter and more adpressed than those on sternite 2 --> pedissequum?
5) 1 pale mark on the thoracic pleura on each side --> pedissequum

So which species does the specimen belong to? Caught 3 weeks ago in Dornbirn/Austria
