The threshold behavior of $e^+ e^-$ annihilation is considered in thechannels $B_{s0} \bar B_s^* + c.c.$, $B_{s1} \bar B_s + c.c.$, and $B_{s1} \barB_s^* +c.c.$, where $B_{s0}$ and $B_{s1}$ are the excited bottom-strange$J^P=0^+$ and $J^P = 1^+$ mesons. It is argued that due to the heavy quark spinsymmetry (HQSS) only one coherent combination of the first two channels isproduced in the $S$ wave as well as the third channel. Thus, if there existthreshold molecular peaks in the considered channels, only two of such peakscan be formed in the annihilation. The properties of such threshold states arediscussed, including the heavy-light spin structure and the related transitionsto bottomonium plus light mesons, as well as mixing with the channels with andwithout hidden strangeness.

Some properties of the states at the hidden-strangeness mixed ${1 \over 2}^+ + {1 \over 2}^-$ heavy meson pair threshold in $e^+e^-$ annihilation
