Status Current knowledge is that Schmarda (1861) combined different but related intertidal species from two places in his description of Placostegus caeruleus, namely Cape of Good Hope, South Africa and New Zealand. The type material is believed lost (Glasby & Read, 1998). The Cape of Good Hope material was what is now Spirobranchus kraussii (Baird, 1865), and the New Zealand material was what is now Spirobranchus cariniferus (Gray, 1843). Schmarda's colour plate of tube and worm is probably more like the South African species than the New Zealand species, but his name cannot be assigned as a synonym to just one of them as he didn't indicate which he based the description on, presumably finding the specimens indistinguishable. His name is junior to both taxa, so there is currently no nomenclature issue arising from the uncertainty of identification. [details]

Editor's comment Schmarda's material from Cape of Good Hope belongs to Pomatoleios kraussii (fide Zibrowius 1973); however that from New Zealand should be attributed to Spirobranchus cariniferus (fide Glasby & Read 1998) [details]Etymology Not stated, but 'caeruleus' is Latin for sky blue. In reality the radiolar fan of Pomatoceros caeruleus is a darker blue than sky blue [details]
