Rostanga sp.

( Figure 18 K )

Material examined. One specimen. MB28-004617, BL, 26 Aug. 2012, 3m, 13mm. Habitats. Subtropical tidal reef and seagrass.

Occurrences. Barra and Zavora.

Geographic distribution. Indo-west Pacific. Indonesia (Gosliner et al. 2015) and Mozambique. Remarks. This specimen is externally similar to Rostanga elandisa Garovoy, Valdés & Gosliner 2001 , which has been previously found in the cold Atlantic coast of South Africa and to R. aureamala Garovoy, Valdés & Gosliner (2001) , which was described based on material from South Africa collected in the Indian Ocean coast. The radula of the specimen from Mozambique differs from both species by the wider shape of the inner lateral teeth that contains at least 5 well-defined denticles. This specimen is externally similar to a putative undescribed species from Indonesia illustrated in Gosliner et al. (2015, pg. 198, bottom right).
