It is shown that the signal recently reported by the Belle Collaboration (Phys. Rev. Lett., 101 (2008) 172001) contains clear signs of the and the vector states, and also some indication for the masses and widths of the and . Moreover, it is argued that the threshold behaviour of the cross-section suggests the presence of the hitherto undetected state not far below the threshold.
