This is interesting, and it looks a bit like the hybrid. Please also see the discussion on hybridisation in Bohadshia in here:

Pictures of all the types are available on the BOLD website…

This looks like another example of whatSun, Alex and Gustav nominated as a '...putative argus-vitiensis hybrid with vitiensis background colour and ocellar spots similar to argus'. This is in their 2013 paper in the Zoological Journal of the Linnean Society (Colour, confusion, and crossing: resolution of species problems in Bohadschia (Echinodermata: Holothuroidea).
I just received this photo (without sample nor spicules) from Mauritius, I believe it is a Bohadschia, but which species please?
