Comment from Richard Willan on photo #233
In answer to this particular question, I have to say the distinction between Platydoris formosa and P. cinerobranchiata is very confused at the moment. These differences are far more complicated than one species having red rhinophores, and this year I have seen a manuscript considering the differences. This paper is not published yet. It is best to leave this photo as P. formosa for now.

You can see the spots on the rhinophore pockets of the brown animal (and its red rhinophores) and the spots on the gill pocket of the red animal.

Comment from Scott Johnson on photo #24584
The stippled pattern (as opposed to lines) and red rhinophores make me suspect this is more likely a form of Platydoris formosa.

Comment from Richard Willan on photo #2682
Some species of Platydoris are quite difficult to separate just from above (Platydoris formosa, Platydoris ellioti, Platydoris cinerobranchiata). They really need a photo showing the pigmentation pattern on the underside as well for certain identification.

Comment from Richard Willan on photo #2482
A slightly atypical individual that has some discrete blood-red spots in addition to the ‘regular’ red-brown blotching.
