Thanks for re-opening the forum! I'll try to contain my enthusiasm and limit my entries to the more interesting critters I've found.
This is Cyerce nigra (presuming it is distinct from C. nigricans ).
Locality: Dinah's Beach/Lauadi, 10 meters, Milne Bay, PNG, Pacific, 5 April 2007, Sandy Bottom with occasional coral. Length: 20 mm. Photographer: Clinton Bauder.

Photos like this are very useful in building up information on colour variation. If we are going to work out whether C. nigra and C. nigricans are different species, we will need photos like yours to show how consistent the colour differences are - then all we will need is someone to compare their anatomy.
