"At present this individual would have to be classified as Risbecia godeffroyana simply because it does not come from Hawaii. However, in lacking a strong pink suffusion over the central area of the mantle, in having dark blue-black ‘tongues’ laterally and in having only a few orange spots inside these ‘tongues’ it would qualify as Risbecia godeffroyana on its appearance. So in my opinion, this animal (and plenty of other intermediates like it) shows there is insufficient colour differences to separate Risbecia imperialis and Risbecia godeffroyana, and they should be synonymised. In that case, the name Risbecia imperialis must apply because it is the older name."
