Psamathini are a tribe of phyllodocid "bristle worms" (class Polychaeta) in the family Hesionidae. They are (like almost all polychaetes) marine organisms; most are found on the continental shelf, but some have adapted to greater depths down to the abyssal plain.[1]
Their dorsal cirri alternate, and they usually lack facial tubercles. Most have prolonged teeth on the chaetal blades. 5 genera are placed in the Psamathini with certainty, and three further ones are often included here too in recent times, to make this tribe refer to a distinct clade of polychaetes:[2]
- Bonuania Pillai, 1965 (tentatively placed here)
- Hesiospina Imajima & Hartman, 1964
- Micropodarke Okuda, 1938 (tentatively placed here)
- Nereimyra Blainville, 1828 (= Halimede Rathke 1843 (non de Haan, [1835]: preoccupied), Psammate)
- Psamathe Johnston, 1840 (= Kefersteinia)
- Sirsoe Pleijel, 1998 (tentatively placed here)
- Syllidia Quatrefages, 1866
- Vrijenhoekia Pleijel, Rouse, Ruta, Wiklund & Nygren, 2008
