The analysis of mass spectra and the study of strong decays indicate that $X(2120)$ and $\\eta(2225)$ associated with $\\pi(2070)$ and the predicted kaon $K(2150)$ may form a new pseudoscalar meson nonet. In addition, more experimental data for $X(2100)$ are necessary to determine its structure of nonets. Then, $X(2500)$, $X(2370)$, $\\pi(2360)$, and the predicted kaon $K(2414)$ can be grouped into another new nonet.
