* Goniobranchus cf. albonares (Rudman, 1990) Figure 9L

Material examined.

Three specimens 4-6 mm, CB.

Ecology.

Observed under dead fungiid coral skeletons and occasionally among rubble in shallow coral reef. Depth 3-8 m

Distribution.

Goniobranchus albonares is known from Australia ( Rudman 1990), Japan ( Gosliner et al. 2008), Madagascar ( Rassat 2016), and Mozambique ( Tibiriçá et al. 2017).

Remarks.

Externally resembling both Goniobranchus albonares (Rudman, 1990) and Goniobranchus rubrocornutus (Rudman, 1985), the present species differs from the former by possessing a broken submarginal band of deep red and from the latter by the presence of completely white rhinophore clubs and gills as opposed to red. There is significant overlap in the range of both species, with G. rubrocornutus known from Australia, Hong Kong, and Japan ( Rudman 1985). A comprehensive comparison of the three species is needed.
