The polychaete family Trochochaetidae Pettibone (=Disomidae Mesnil) is reviewed, and a key to the species of
Trochochaeta Levinsen (=
Disoma Oersted) is included. Based on new material and examination of types, the descriptions of three species are supplemented:
T. carica (Birula), new combination;
T. watsoni (Fauvel); and
T. diverapoda (Hoagland). A new species from West Africa,
T. kirkegaardi, is described.
