Tayuva lilacina ( Gould, 1852)

( Figure 17 G–I )

Material examined. Three specimens. MB28-004964, ZRS, 0 2 Feb. 2015, 27m, 50mm. MB28-004803, ZRP, 0.5m, 7mm; MHN-YT1278b, NHR, 2m, 30mm.

Habitats. Subtropical rocky reefs, wreck and tropical coral reefs, under rocks.

Occurrences. Zavora and Nuarro.

Geographic distribution. Indo-west, central Pacific. Hawaii (Gosliner et al. 2008; Dayrat 2010), Japan, Indonesia, Philippines ( Dayrat 2010), Papua New Guinea, Australia, Singapore ( Coleman 2008), Guam ( Carlson & Hoff 2003), South Africa, Tanzania, Madagascar ( Dayrat 2010) and Mozambique.

Remarks. Tauyuva lilacina and Sebadoris fragilis Alder & Hancock, 1864 are two externally similar species. Externally they can be distinguished by the ventral surface, which in S. fragilis is pigmented by dark larger spots and in Tayuva lilacina covered by small brown dots ( Dayrat 2010). Nevertheless, young S. fragilis could be misidentified as T. lilacina , thus we examined the reproductive system of the 50mm specimen (MB28-004964) and
