Flotidae is a family of pelagic polychaete worms, sometimes synonymized with Flabelligeridae, which they closely resemble.

Other sources consider them the sister taxon to Flabelligeridae and closely allied to the latter group.

[1][2] Flotidae originally contained one genus, Flota, from which it derives its name, but a 2007 study also placed Buskiella in the family, and moved all (two) Flota species to Buskiella.

[3][4][1] The family would thus contains one genus and three species, listed below.

[1] However, defenders of the separate family status of Flotidae cite several morphological differences.
