A revision of Sabellastarte (Polychaeta: Sabellidae)

Abstract

Sabella indica Savigny, 1822 (‘Indian Ocean’) is the type of Sabellastarte, but that name is preoccupied in the Pectinariidae. Sabellastarte sanctijosephi (Gravier, 1906, as Eurato, from Djibouti) has sometimes been used in its place, ignoring more suitable forms and older names. Sabellastarte spectabilis (Grube, 1878, Philippines) with an Indo-Pacific distribution is the best replacement name for S. indica, better than Sabellastarte pectoralis (Quatrefages, 1866, as Sabella) which also occurs in the Indian ocean. Sabellastarte magnifica (Shaw, 1800, Jamaica) is distinct from Indo-Pacific forms and a neotype is selected. Unlike the above species, Sabellastarte fallax (Quatrefages, 1866, as Sabella, location unknown) has a short crown relative to the body, as in Sabellastarte australiensis (Haswell, 1884, as Spirographis, New South Wales) and Sabellastarte japonica (Marenzeller, 1885 as Laonome, Japan), but both the latter differ in having bispiral crowns. Sabellastarte pottaei Quatrefages, 1866, as Sabella, New Caledonia) is a synonym of S. japonica, but rules of priority should be waived. Sabellastarte samoensis (Grube, 1870a as Sabella) and Sabellastarte sanctijosephi are least like the ‘indica’ concept. These and those above are redescribed and species removed from Sabellastarte are listed.
