Dear Dave,

This dorid appears to be widespread in the Indo-West Pacific but there is still considerable confusion over its identity. Malcolm Edmunds (1971)identified it as Peltodoris mauritiana Bergh, 1889 but he wasn't sure his specimens were all the same or very confident that many of the species named by Bergh and others as Discodoris and Peltodoris were identifiable today. So my identification of this as Discodoris mauritiana is mainly because I have always called it that, rather than from any deep understanding of this groups of greyish, mottled 'flat dorids'.

They are a group which need work.
