It is similar in shape to larger Samla riwo, including the long oral tentacles with flattened tips. It differs by the colour pattern of the cerata, oral tentacles and the body.
One more species with that kind of oral tentacles is Samla bilas.
Pretty similar is Samla cf. bicolor, which differs by the long cerata, and by the lack of the flattened tips of the oral tentacles.
This species was posted on 6 June 2003 at these websites as Flabellina bicolor (Kelaart, 1858) [Eolis],
Korshunova et al. (2017) reinstated the genus Samla Bergh, 1900 within the new family
Samlidae Korshunova, Martynov, Bakken, Evertsen, Fletcher, Mudianta, Saito, Lundin, Schrödl & Picton, 2017,
and moved Flabellina bicolor (Kelaart, 1858) into the genus Samla Bergh, 1900.
I changed it on 5 December 2017 into Samla bicolor (Kelaart, 1858) [Eolis].
