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]

Genera

5-8, see text

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]
