The upper picture is S. mehadiae. Both species may occur sympatrically and in greater numbers (Bohemia: around Hlubok√°), which was proved by examination of their genitalia. Still, I have never seen both on the same trunk. They are stenotopic, prefer natural decidual forests. Both were collected from Austria only very long ago, the new findings reward publication. It would be of help if you would collect at east S. hypoleuca in order to prove some morphologic details. This needs good luck, I cross my fingers.
