Here's one of the tough little fuzzy white dorids we get around British Columbia. It does have distinct star like pattern of spicules around the tubercles, hence my thinking it may be Adalaria proxima. The gills however, look to be in a circlular formation, but that may just be the angle the photo was taken from.

You are absolutely right on - next to those confusing Doto's, these FWDftNWP (that is Fuzzy White Dorids from the North West Pacific) are a nightmare. I consulted with FWDftNWP guru Sandra Millen and her response was - "It looks like a white Doris montereyensis but it probably is an Aldisa tara. Without the gills showing it is hard to be sure."
I tend to agree because of the low tubercles on your critter (those on Adalaria are tall and papillate). Lets go with Aldisa tara, for now.
