A new charm-strange meson, the Ds1∗(2863), has recently been observed by the LHCb Collaboration which also determined the DsJ∗(2860) to have spin 3. One of the speculations about the previously observed Ds1∗(2710) is that it is the 1D31(cs¯) state. In this paper we reexamine the quark model properties and assignments of these three states in light of these new measurements. We conclude that the Ds1∗(2863) and Ds3∗(2863) are the 1D31(cs¯) and 1D33(cs¯) states respectively and the Ds1∗(2710) is the 2S31(cs¯) state. In addition to these three states there are another three excited Ds states in this mass region still to be found, the 2S10 and two 1D2 states. We calculate the properties of these states and expect that LHCb has the capability of observing these states in the near future.
