Jorunna rubescens is very strange looking dorid which looks more like a Nembrotha or Polycera than a species of Jorunna. It was formerly known as Kentrodoris rubescens, but Angel Valdés and Terrence M. Gosliner reviewed the caryophyllidia-bearing dorids. One of their conclusions is that Kentrodoris is a generic synonym of Jorunna.
