Material examined. Ten specimens. MHN-YT10, ZRP, 17 Jun. 2011, 1m, 14mm; MB28-004539, ZRP, 0 6 May 2012, 2m, 14mm, collected by S. Bruck; MB28-004540, ZRP, 0 6 May 2012, 2m, 9mm, collected by S. Bruck; ZMBN117024, ZRP, 0 6 May 2012, 2m, 8mm; ZMBN117058, ZRP, 16 Apr. 2014, 0.5m, 16mm; ZMBN11 7063, POD, 11 May 2014, 15m, 16mm; MB28-004864, 2 spcs., POB, 16m, 6-8mm; MB28-0 0 4983, ZSC, 25 Apr. 2015, 20m, 15mm; MB28-005018, ZRP, 0 4 Aug. 2015, 1m, 16mm.

Habitats. Subtropical tidal reefs and rocky reefs.

Occurrences. Ponta do Ouro and Zavora.

Geographic distribution. Indian Ocean. Sri Lanka ( Yonow 1984), Tanzania, Réunion Island ( Rudman 1987), Madagascar, South Africa (Gosliner et al. 2008) and Mozambique.

Remarks. Specimens show colour variation ranging from a white dorsum with purple mantle edge to a brownish dorsum with light yellow spots inside the purple margin. The latter pattern resembles Goniobranchus aureopurpurus from the West Pacific. Rudman (2005b) suggests that “ G. alius , G. aureopurpureus , G. rufomaculatus and G. albopustulosus ” may be the same species with wide geographic distribution and colour variations.
