Concerning message #20367:

Dear Bill,

Please find attched a few pictures from some more Hypselodoris purpureomaculosa, also from Anilao. I noticed there or 2 colour pattern variations. One with distinct, separate (sometimes touching each other) black spots. And one [lower photo] with more diffuse black spots. Normal variations within the species?

Locality: Anilao, 10-15 meters, Philippines , 6 to 13 July 2008. Length: 8 cm. Photographer: Marcel Tanke.

Best regards,
Marcel

Dear Marcel,

I think we can say this is normal variability in the species. It usually takes a few years after a species is described before we can be sure we have a good idea about its variability. In some cases we find that what looked like a perfectly 'good' species when it was first named turns out to be just a colour variation when we learn more about it. Posting variations on the Forum like this is a very useful way to accumulate more information on these species.

Best wishes,
Bill Rudman
