  We report the observation of a new DsJ meson produced in B+ -> D0-bar DsJ ->
D0-bar D0 K+. This state has a mass of M = 2715 +-11(stat) +11-14(syst)
MeV/c^2, a width Gamma = 115 +-20(stat) +36-32(syst) MeV/c^2 and a spin-parity
1-. The results are based on an analysis of 449 million BB-bar events collected
at the Upsilon(4S) resonance in the Belle detector at the KEKB asymmetric
energy e+e- collider.
