Bill,
You are right that calling the species Glossodoris sp. 2 in the South African book was largely a timing issue that your monograph on Glossodoris was not out by the time the book went to press. However, I am not entirely convinced that the animals that both Valda and I have seen from South Africa and that you have from Tanzania are the same species as Glossodoris cincta. The color pattern, different colored marginal and submarginal lines and black lines on the gills appear very different from specimens of G. cincta from both the western Pacific and the Indian Ocean. I recall that their radular teeth were very similar to those found in typical cincta, but I still think it is worthy of some additional investigation.
All the best,
Terry

Thanks Terry,
I agree that ome of these 'species' are not easy to determine. At that time I considered the radular morphology and anatomy of the foregut and the reproductive system to be so similar in the three colour 'forms', that they best be considered geographic colour variations. Your comments suggest you have records of the western Pacific cincta colour form from the western Indian Ocean.

I guess its a bit like the Noumea haliclona species group in south eastern Australia. Nature sometimes is not kind when we want to put things into neat little boxes.
Best wishes,
Bill Rudman.
