Note added 12 January 2010: I have posted a message today showing a specimen of Paradoris from New Zealand with the characteristic brown marks of P. dubia which suggests Dayrat's synonymy of P. leuca with P. dubia is correct. See message #23082

This main external feature distinguishing this species from other related dorids is its white colour and dark brown rhinophores.

In a recent revision of the genus Paradoris it is suggested that P. leuca is a synonym of the southern Australian species, Paradoris dubia (Bergh, 1904) [Dayrat, 2006)].  However, as Benoit Dayrat notes in his revision, we know so little about the colour of most species of this genus that, synonymising these species at present would seem a bit premature. The only colour photos I have seen of the New Zealand animals are those now on the Forum and they lack the colour patterning found in Australian P. dubia. It would seem appropriate at this stage to wait and see if specimens with the Australian colour pattern are found in New Zealand.
