Dear Kristin,

It looks as though Hypselodoris whitei and H. maridadilus will haunt me for ever. As you will see from the various discussions accompanying messages on both species, I have some doubts about whether there are one or two species.  The form with white-tipped rhinophores is typical of the west Pacific species, H. whitei, so even though yours is from the Indian Ocean it is best to consider it to be H. whitei. As you will see we have records of this white-tipped form from the Maldives, so either the two species overlap in the eastern Indian Ocean or the this is where the colour forms of one species merge.

Best wishes,
Bill Rudman
