Stackelbergiella Marikovskij, 1958

Stackelbergiella is a uniform, Palearctic genus that previously comprised two species: S. hordei (Barnes), which is widely distributed in mainly the western Palearctic region, and S. rickebasta Jaschhof, known from a single specimen from central Sweden (Jaschhof & Jaschhof 2013: 355ff.). The description presented here of a third Stackelbergiella is, again, based on a very small specimen sample, consisting of two males from Sweden and Estonia.
