Eubranchus amazighi sp. nov. (Gastropoda, Heterobranchia) is described based on two specimens collected at the harbour of Agadir (Morocco, Atlantic). The translucent white ground colour with opaque white and red-orange speckles over the dorsum and cerata, smooth rhinophores and morphology of the lateral teeth of the radula characterize this species, which is compared with all the Atlantic and Mediterranean red/orange-spotted species of the genus.
