Translucent pinkish to pale violet body with three continuous red-purple lines along the back from head to tail. Long, papillate rhinophores; cerata in stalked groups with purple, red or orange tips.
The native Flabellina affinis and Edmundsella pedata are violet all over but lack the three red lines.
Rocky reefs and hard substrate, ~5–30 m.
Hydroids, especially Eudendrium and Pennaria disticha.
