If we are talking Cossuridae taxonomy in general I think the paper below might still be the most recent overlook, even though nearly eight years old.
Read, G. B. 2000: Taxonomy and distribution of a new Cossura species
(Annelida: Polychaeta: Cossuridae) from New Zealand.
Proceedings of the Biological Society of Washington 113(4): 1096-1110.
World species were tabulated and Cossurella was sunk.
