Planocera pellucida , together with Pseudoceros wirtzi , Pseudoceros cf. maximus and Prostheceraeus giesbrechtii are the three polyclad species currently recorded for Madeira. As can be seen in Fig. 7J . The specimens of Planocera pellucida from Madeira do not differ molecularly from those captured in the Canary Islands.
