Thordisa cf. sanguinea Baba, 1955

( Figure 17 J )

Material examined. One specimen. MB28-004806, ZRP, 17 Mar. 2014, 0.5m, 19mm.

Habitats. Subtropical tidal reef, under rock.

Occurrences. Zavora.

Geographic distribution. Indo-west Pacific. Japan ( Baba 1955) , Philippines (Gosliner et al. 2015) and Mozambique.

Remarks. This specimen is similar to Baba’s description (1955) of Thordisa sanguinea and is very similar to T. sanguinea from the Pacific (illustrated in Gosliner et al. (2015), pag.178). The only difference is that the three or four darker areas mentioned by Baba (1955) are not clearly visible in the specimen collected by us. Therefore, additional material from the western Indian Ocean and further anatomical and/or molecular examination is needed in order to confirm the identification of this species.
