Janolus sp. 2

( 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).
