Stylocheilus longicauda is characterized by a bright yellowish-green body colour and blue spots circled with orange-red. The name longicauda [=long tail] refers to the long slender, almost ribbon-like, posterior tip of its foot. There are scattered short white papillae over the body.
For a long time the name Stylocheilus longicauda was used for the more common species Stylocheilus striatus, Bill Rudman discusses the correct identity at the Sea-Slug Forum.
Pretty similar are
Petalifera ramosa which differs by the bownish or green body colour, firm conical tubercles with white basal ocelli and terminal papillae, and a short tail
Petalifera cf. ramosa which lacks the blue spots with orange ocelli and has a short 'tail'
