Goniobranchus decorus ( Pease, 1860)

( Figure 6 I )

Material examined. One specimen. MB28-004594, ZDRS, 21 Jun. 2012, 30m, 9mm.

Habitats. Subtropical rocky reef.

Occurrences. Zavora.

Geographic distribution. Indo-west, central Pacific. Marshall Islands, Papua New Guinea, Australia, Philippines, Christmas Island (Gosliner et al. 2008), Réunion, Mayotte ( Bidgrain 2005b), and Mozambique.

Remarks. This species is very similar to G. setoensis ( Baba, 1938) but has purple spots on the white midline, which is not mentioned in Baba’s description (1938). Gosliner et al. (2015) cite that G. setoensis and G. decorus might (or not) represent the same specie.
