It is suggested that the recently observed enhancement of the relative yield in $e^{+} e^{-}$ annihilation of states with hidden charm and hidden strangeness above 4.43 GeV is associated with the S wave production of the charmed strange meson pairs $D_{s 0} (2317) {\bar{D}}_{s}^{*} + c . c .$ and $D_{s 1}^{*} (2460) {\bar{D}}_{s} + c . c .$ This mechanism implies a pattern of breaking of the Heavy Quark Spin Symmetry (HQSS) that can be tested in the final channels such as $η_{c} (1 S) φ$ , $h_{c} (1 P) η$ , $h_{c} (1 P) η^{'}$ produced in the same energy range.
