I looked at all the pictures on your Placida dendritica Polynesia - NW Pacific Page, and I think we may have 3 genera involved here. Bob Bolland's animal looks most similar to the "real" (European) P. dendritica. I have already commented on the species from French Polynesia, which I think is a species of Ercolania. The species from Taiwan looks rather similar to the amphi-Atlantic Stiliger verticillata (Ortea, 1982). Ortea described it as Placida verticillata from the Canary Islands, but Kerry Clark had collected this species in Florida, and had a description almost completed when Ortea's paper came out, and if I remember right, we had decided that it was a Stiliger based on the reproductive anatomy (no penial stylet is the one character I remember). So we definitely need to look at anatomy - and maybe DNA to sort these out.

I am glad I didn't try and identify them.
