Nudi ID help

Hello,

I found this guy in Gili Trawangan and was not sure which species it was, my best guess was Tritonopsilla alba but am definitely not sure. Any help would be greatly appreciated as seaslugforum.net is inactive at the moment.

Heres the link:

It was found at 5 meters on a night dive.

Thanks,

Fontaine

That's one possibility. There are also some similar Marionia species. Do you have a photo of it from above that shows the back? That would be helpful in deciding where to put it.

Here are the other pics I got of this one, think the first one is the best back picture I managed to get. Thanks Leslie!
