Using a sample of $(448.1\ifmmode\pm\else\textpm\fi{}2.9)\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $\ensuremath{\psi}(3686)$ events collected with the BESIII detector, we perform the first partial wave analysis of $\ensuremath{\psi}(3686)\ensuremath{\rightarrow}{K}^{+}{K}^{\ensuremath{-}}\ensuremath{\eta}$. In addition to the well established states, $\ensuremath{\phi}(1020)$, $\ensuremath{\phi}(1680)$, and ${K}_{3}^{*}(1780)$, contributions from $X(1750)$, $\ensuremath{\rho}(2150)$, ${\ensuremath{\rho}}_{3}(2250)$, and ${K}_{2}^{*}(1980)$ are also observed. …
