We consider the spin-coupling for one electron-hole pair bound in single self-assembled quantum dots. The long-range exchange coupling leads to a vanishing spin splitting of the ground interband transition in cylindrical dots. We evaluate the spin-splitting for di erent electron-hole levels of non-c
