  The meson family of $\eta$ pseudoscalars is studied in the context of the
AdS/QCD correspondence and the differential configurational entropy (DCE). For
it, two forms of configurational-entropic Regge-like trajectories are
engendered, relating the $\eta$ mesonic states excitation number to both their
experimental mass spectrum in the Particle Data Group (PDG) and the DCE as
well. Hence, the mass spectrum of $\eta$ pseudoscalar mesonic states, beyond
the already detected states $\eta(550)$, $\eta'(958)$, $\eta(1295)$,
$\eta(1405)$, $\eta(1475)$, $\eta(1760)$, $\eta(2225)$, and $\eta(2320)$, is
derived for any excitation number. The three first ulterior members of this
family are then analyzed and also compared to existing candidates in PDG.
