Unknown nudibranch from North Sulawesi - Cuthona Sp.?

Hello everyone - I can not possibly identify this nudibranch from North Sulawesi. Most likely to me seems Cuthona Sp. Or maybe it is some kind of Flabellina?

Thanks, Timon

Has a Flabellina look. I like it..Nice pic.

Cuthona ornata?

Appears to be Tenellia sp. (known as Cuthona) similar to the photos found at http://www.underwaterkwaj.com/nudi/eolids/e639.htm.
