Marioniopsis sp. B differs from Marioniopsis sp. A by the white band in the centre of the mantle. Marioniopsis sp. C could be a colour variant of Marioniopsis sp. A, but this has clear dark blue ornaments, in Marioniopsis sp. C this is indistinct. There are many tritoniids with a similar colour pattern, even the bright blue spots are not distinctive - or there is one species with many colour variants.
