Although a bit more orange in the body, this appears to be the species called Flabellina sp. 1 in Gosliner et al 2008. It is somewhat similar to Flabellina rubrolineata, but it lacks the three purple to red lines that run along the body in typical specimens. We have seen about eight of these at Tulamben and they all looked pretty much alike. F. rubrolineata is supposed to be quite variable in color, so perhaps this one can fall within that range of variation. It is also very similar to some color forms figure on web sites of the newly described and highly variable Unidenta angelvaldesi, but members of that species have tall, smooth rhinophores. The first series of photos are of specimens observed in November 2012.
The three photos below show specimens found in November 2014. They seem to be associated with the magenta hydroid in the lower photos.
