The manuscript describes progress in analyses of several extremely complex spectra and for the first time reports observed and accurately measured spectral lines of 8-times ionized tungsten, W IX, albeit only one of them with a tentative energy-level identification. The results have potential applications in fusion energy research, as well as in analyses of hitherto unknown spectra of atomic ions with open 5d and 4f shells. The manuscript is well-written and includes proper references to
