(Figure 28 E)

Material examined. One specimen. MB28-005029, POB, 18m, 18mm.

Habitats. Subtropical rocky reef.

Occurrences. Ponta do Ouro.

Geographic distribution. Western Indian Ocean. Mauritius (Armin 2010b) and Mozambique.

Remarks. This species appears to be undescribed. It resembles the illustration of the species identified as Janolus toyamensis Baba & Abe, 1970 in Gosliner et al. 2015 (pag. 305, top two photos). However, the specimen examined here and in Gosliner et al. (2015) has a long pointed tail, while the type material of J. toyamensis has a broad rounded foot with no tail crest (Baba & Abe 1970). Moreover this specimen lacks the dark brown spots on the foot cited in the first description of J. toyamensis and has a subapical blue ring in the cerata and a blue edge on the tail, which is not mentioned by Baba & Abe (1970).
