Perchloric acid is called perchloric acid on Wikipedia, and chloric acid is called chloric acid. I just checked.
There is a more systematic nomenclature where the oxidation state of the central atom is used instead of potentially ambiguous prefaces or suffixes.
Thus HClO4 is chloric(VII) acid, and HClO3 is chloric(V) acid.
Similarly H2SO4 is sulfuric(VI) acid and H2SO3 is sulfuric(IV) acid, and so on.
