This is an unidentified or undescribed species of the genus Sagaminopteron - I call it Sagaminopteron sp. 04, to distinguish it from other undescribed species of Sagaminopteron.
Sagaminopteron sp. 04 is is characterized by a whitish colour, orange borders at the parapodia, and by an orange line on the siphon.
There are some better pictures of this species from the Marshall Islands online.
Somehow similar is Siphopteron quadrispinosum which differs by a red siphon and by a red flagellum.
