This Eubranchus resembles E. rubropunctatus but lacks the blue bands on the cerata, tends to have a bluish or purple cerata tip with a yellow subapical band, and has smooth rather than warty rhinophores. There are also similarities to Eubranchus ocellatus. Eubranchus sp. b056 has very small rings similar to but much smaller than those in E. ocellatus. Numerous specimens were found on hydroids on the black sand slope off Tulamben, particularly on our October/November 2018 visit. We have also seen it in the Padangbai area. It appears to be the species called Eubranchus sp. 2 in Gosliner et al (2018).
