Concerning copepods on Sabellids, I got this information from Rony Huys:
Hope that is useful

Rony writes:
The copepods are most likely members of the Sabelliphilidae Gurney, 1927
(order Poecilostomatoida) which are associates of polychaete worms, the
only exception being Phoronicola which was found on a phoronid worm in Hong
Kong. The host taxa of the remaining genera are all tubicolous polychaetes,
usually either members of the Sabellidae (copepod genera Sabelliphilus M.
Sars, 1862; Myxomolgus Humes & Stock, 1972 ; Myxomolgoides Humes, 1975; and
Nasomolgus Sewell, 1949) or of the family Serpulidae (genera Serpuliphilus
Humes & Stock, 1972 and Acaenomolgus Humes & Stock, 1972). The host of
Eupolymniphilus Humes & Boxshall, 1996 belongs to the Terebellidae.
Useful references are:

A key to genera of Sabelliphilidae is found in:

(Copepoda: Poecilostomatoida), with the recognition of six new families.
