  We suggest that the J/psi phi structures observed by LHCb can be fitted in
two tetraquak multiplets, the S-wave ground state and the first radial
excitation, with composition [cs][cbar sbar]. When compared to the previously
identified [cq][cbar qbar] multiplet, the observed masses agree with what
expected for a multiplet with q -->s. We propose the X(4274), fitted by LHCb
with a single 1^++ resonance, to correspond rather to two, almost degenerate,
unresolved lines with J^PC = 0^++, 2^++. Masses of missing particles in the 1S
and 2S multiplets are predicted.
