It is predicted that in 2D magnonic crystals the edge rotational magnons of forward volume magnetostatic spin waves can exist. Under certain conditions locally bounded magnons may appear within the crystal consisting of the ferromagnetic matrix and periodically inserted magnetic/nonmagnetic inclusions. It is also shown that interplay of different resonances in 2D magnonic crystal may provide conditions for spin wave modes existence with negative group velocity.
