It is my experience that similar structures are present on the antennae,
dorsal cirri, sometimes ventral cirri, sometimes scattered on parapodia and
elsewhere on basically every polychaete I have had the opportunity to study.
Back in Pleistocene, before SEM, we used to refer to them, informally as
epidermal sensory structures, without any evidence of structure or function!
Now we know what they look like, at least....
