Tropical western Pacific ("Aibukit")
Described by Bergh from a preserved animal as Nembrotha diaphana. Radula description shows it to be a species of Tambja. Most important part of his description is the line "Color animalis vivi?" - which I translate as "colour of live animal unknown". It is my opinion that such descriptions are worthless, as there is little important differences in the radular morphology of most species of the genus. The name should be treated as unidentifiable.
