Gymnodoris sp. 3

( Figure 26 F )

Material examined. One specimen. ZMBN105116, VIMN, 17 May 2015, 0.2m, 19mm, collected by Y. Tibiriçá and M. Malaquias.

Habitats. Tropical tidal reef.

Occurrences. Vamizi Island.

Geographic distribution. Western Indian Ocean. Mozambique.

Remarks. The anterior part of the head is ovate. The gill branches are large and form a completed circle around the anus, located on the posterior one third of the body. The mantle is translucent yellow with darker yellow spots. The visceral content and the eye spots are visible through the mantle. The rhinophores are yellow and bear eight lamellae. The anterior end of the foot is lobed. This species appears undescribed and it is externally similar to Gymnodoris sp. 4 and Gymnodoris sp. 5 in Gosliner et al. (2015, pg. 153), but anatomical and molecular analyses are needed to confirm this hypothesis and the correct distribution of this species.
