Hi Bill,
I think Takako's animal is the same as my one which you labelled Costasiella cf. kuroshimae
Cheers Erwin

Dear Erwin,
I guess its possible they are the same but as I said in my earlier comment, many of these species have been named from one or very few specimens so we have no idea how variable they are in colour. While the absence of a red spot and scattered blue spots on the cerata of your animal may be a variation, I would find it less likely that the difference in rhinophore colour is just a variation. In Takako's animal there is a black line along the upper half of the dorsal side of the rhinophore, while in your animal the whole of the upper half of each rhinophore is black.
Best wishes,
Bill Rudman
