Description
Summary:Hesiospina Imajima and Hartman, 1964 (Psamathini, Hesionidae, Polychaeta) is revised based on examination of all available types, other museum specimens and a large number of newly collected specimens from world-wide areas. Two species are recognized and redescribed, Hesiospina aurantiaca (Sars, 1862 ), new combination, and H. vestimentifera Blake, 1985 . The currently used name Hesiospina similis (Hessle, 1925 ) is treated as a junior synonym of both Hesiospina aurantiaca and Castalia longicornis Sars, 1862 . A lectotype is designated for H. aurantiaca, and the same specimen is used as neotype for C. longicornis, making the two objective synonyms. Hesiospina aurantiaca is widely distributed and recorded from the Caribbean, Gulf of Mexico, European Atlantic and Mediterranean waters, Japan, Papua New Guinea, the Great Barrier Reef, and New Caledonia, mainly from shallow waters, but down to over 500 m depth. Whereas there are some differences between populations from different regions, including distribution of uni- and bidentate chaetae, the different populations are not characterized by any obvious apomorphies and are treated as a single species. Hesiospina vestimentifera is associated with hydrothermal vents and is widely distributed in the east Pacific.
