* Gymnodoris sp. 4 Figure 16D

Material examined.

One specimen 9 mm, TW.

Ecology.

In soft sediment habitats beyond fringing coral reefs. Depth 12-16 m.

Distribution.

So far only recorded in the Gulf of Thailand.

Remarks.

Incorrectly identified as Gymnodoris bicolor (Alder & Hancock, 1864) by Mehrotra and Scott (2016) due to low quality images, additional material has shown several unique differences, including translucent club-shaped gills with yellow tips in an arc and a prominently raised area between the eyes, behind the rhinophores.
