Described as the hydroxyl analogue of baratovite, which had originally been described as fluor-dominant. Some mineralogists now claim that baratovite is also hydroxyl- rather than fluor-dominant, and that baratovite and katayamalite are therefore the same species, with the name baratovite having priority. At present this situation has not been clarified and katayamalite remains an IMA-approved species.
