  The $eta_L(1410)$ component of the $\eta(1440)$ pseudoscalar has strong
affinity for glue. But its mass is incompatible with lattice simulations that
predict a much higher value for the $0^{-+}$ glueball. As a consequence it has
been suggested that $\eta_L(1410)$ could signal physics beyond the Standard
Model. Here we argue that if glueballs are closed gluonic fluxtubes then
$\eta_L(1410)$ is a prime candidate for the $0^{-+}$ glueball. Furthermore, in
the absence of parity violating terms its mass should be degenerate with that
of the $0^{++}$ glueball. We also suggest that the decay properties of such
glueballs could be employed as probes for extra dimensions.
