There are many colour variations within Flabellina rubrolineata. It usually has red longitudinal lines on its body, one down the centre of its back and one down each side of the body just below the cerata, but these lines can sometimes be broken, or be totally absent. The rhinophores are papillate, often with a reddish apex.
I have posted more pictures of Flabellina rubrolineata than usual, to show some of its colour variations.
Pretty similar are:
Flabellina cf. rubrolineata which has smooth rhinophores, and
Flabellina sp. 04 which has a broad opaque white band at the smooth rhinophores.
