NOTES. Here H. scotosiata for the first time is reliably given for Irkutskaya oblast. The find of this species closes the gap in its range. The male and female genitalia of this rare species are illustrated ( Figs 21–23). By appearance, moths of H. scotosiata can be confused with similar Siberian species, Horisme falcata (Bang-Haas, 1907).
