Concerning message #20542:
Reunion Island seaslugs
Are these a variant of Platydoris cruenta or P. striata? These two different specimens (upper photo from Madagascar and lower photos from Reunion Island) look like P. striata but also to the supposed P cruenta specimen (see my preceding message #20613 ). I haven't good photo of the underside of these specimens, only an old photo of a dead specimen which are very similar to our P. cruenta specimen ( brown lines not dots and absence of red patches)
Photos: Length: 50-70 mm. Photographer: Alain Barrére.
All these specimens are very similar except for the very small red patches on the dorsal side of the 'P. cruenta'.
What's your opinion about these specimens ?

I would agree there is little to separate P. striata and P. cruenta other than the red spots in the latter but as I have discussed previously [message #20542] I think we need a case to be made for synonymising the two species.
