We consider the flavour sextet of charmed meson resonances with Jᴾ = 1⁺ quantum numbers that is predicted by the leading order chiral Lagrangian with up, down and strange quarks. The effect of chiral correction terms as determined previously from QCD lattice data is worked out. Pole masses in the complex energy plane are derived. The most promising signal from such states accessible in experiments like Belle, LHCb and PANDA is foreseen in the s-wave π D* phase shift and the η D* invariant mass distribution. For physical quark masses a rapid variation of the phase shift in-between the η D* and the K D¯* s thresholds is predicted.
