* Hypselodoris cf. kanga Rudman, 1977 Figure 11B

Material examined.

One specimen 40 mm, TW; two specimens 10-25 mm, SB.

Ecology.

Locally found exclusively from deeper soft sediment habitats of the island. Depth 14-25 m.

Distribution.

Misidentified by Chavanich et al. (2013) as H. kanga, with a recorded distribution in both Andaman Sea and Gulf coasts of Thailand.

Remarks.

Hypselodoris kanga bears blueish purple lines across its dorsum which are absent in this species, instead replaced by deep blue, almost black spots. These are more abundant towards the margin where they diffuse outwards turning into blue streaks closer to the edge. Given the historic confusion surrounding H. kanga (see Epstein et al. 2018), this difference in colouration merits the need for a closer investigation.
