Jon,
Yes, I did list a bunch of synonoms. My point was to make sure that we all keep in mind that there are different names for the same substances. In this case, ClO2 and ClO2-.
I did include the chlorous acid, even though it does have a hydrogen molecule: ClHO2. I should have explained. Sorry. Cholorous acid is created during the process of changing a salt form of ClO2 (NaClO2) to the acqueous (spelling sorry) form of ClO2 (added acid). It is described as a chlorite both by the NIH and the Internation Union of... the body that names chemical compounds.
Chlorite-group minerals are also described as chlorites. see below:
