Goniobranchus tennentanus ( Kelaart, 1859)

( Figure 7 D )

Material examined. Six specimens. MB28-004664, ZWH, 0 8 Mar. 2013, 16m, 15mm; MB28-004809, PAE, 0 3 Apr. 2014, 21m, 24mm; MB28-004848, POD, 10 May 2014, 14m, 22mm; MB28-004855, 11 May 2014, POD, 14m, 24mm; MB28-004903, 11 Jun. 2014, MIF, 3m, 6mm. MHN-YT1407, ZWH, 15 Aug. 2014, 15m, 22mm.

Habitats. Subtropical rocky reefs and tropical coral reefs.

Occurrences. Ponta do Ouro , Zavora, Paindane and Mozambique Island.

Geographic distribution. Indian Ocean. Sri Lanka ( Kelaart 1859), British Indian Ocean Territory ( Yonow et al. 2002), Tanzania ( Rudman 1987), Seychelles, Madagascar ( Yonow 2012) and Mozambique.

Remarks. Goniobranchus cavae was synonymised with G. tennentanus by Rudman (1987). Later, Yonow (2012) reassessed both and considered them to be two different species. The colour patterns of the Mozambique specimens are the same as those found in Tanzania ( Rudman 1987), Seychelles and Madagascar ( Yonow 2012). However, it differs from the specimen illustrated by Gosliner et al. (2008, 2015) due the presence of submarginal yellow spots on the mantle. This species shows variation in spots on the dorsum, which can either be solid circles or rings.
