Tambja sp. from Papua New Guinea

Hi Bill,
This is one of many nudibranch species that I will be sending over the next while. I found a number of these colourful critters on a shallow pier dive called "The Slipway" in Kavieng, Papua New Guinea. They were often with Tambja morosa. I can't seem to find it on any website, but seem to recall seeing it in an ID book in Papua New Guinea. It is about 15 cm in length. Can you help me identify it?

Dear Marli,
This has similarities to Roboastra luteolineata but it does not have the prominent oral tentacles so obvious in Robostra. I think it a species of Tambja and I am pretty sure it is the one I have called Tambja sp. 4.

If you have some other photos have a look to see if you have one of it on a bryozoan. Or perhaps one that shows the head f rom a different angle. There seems to be no sign of the oral tentacles in this photo.
Best wishes,
Bill Rudman
