We have stumbled upon a remarkable empirical feature of central meson production which separates established qq mesons from glueball candidates. This does not appear to have been noted previously and we have no simple explanation for it. We suggest that glueballs and qq of the same JPC are distinguishable due to their boson versus fermion internal structure and that this leads to a different topology for central production of glueballs and qq. Upon application of this test to data from the WA102 experiment we find that the f0(1500) and the f2(1900) show behaviour consistent with glueballs and opposite to that exhibited by established qq states.
