Here is a species which I think is Gastropteron from from Kerama Is, near Okinawa.
It is about 4mm long. It was found in dead coral rubble, about 12m depth, in May 1999.

Basically the same questions as for your photos of Siphopteron sp. 1 and Siphopteron sp. 2
I can see dull orange patches on the parapodia, and there appear to be transverse orange lines on the siphon and the foot. Any other colour marks to mention?
