[Notes:

"As pointed out by Cavalier-Smith and Chao (2003b), Desmothoracida are also likely to be Cercozoa; if so, they would belong in this class Proteomyxidea close to heliomonads.

It is unclear whether the order Commatiida Cavalier-Smith 1996/7 (Commation) belongs in Cercozoa or Heterokonta.

Vampyrellida Starobogatov ex Krylov et al. 1980 were formerly included in Monadofilosa (Cavalier Smith 1996/7), but are now left as Protozoa incertae sedis pending molecular evidence."]
