New data from BESIII and LHCb indicate the existence of two hidden charm, open strangeness resonances, dubbed Zcs(3985) and Zcs(4003). Their quasi-degeneracy reproduces, in the strange quark sector, the situation observed with X(3872) and Zc(3900) in the u,d quark sector. The Zcs resonances neatly fit into two broken SU(3)f symmetry nonets with JP = 1+ and opposite charge-conjugation. The mass of the missing element of the nonets is predicted. A short overview of the field will be given.
