Monadofilosa

Monadofilosa is a grouping of Cercozoa.[1] (It is sometimes considered one of three, the other two being Phytomyxa and Reticulofilosa.) These organisms are single-celled amoeboid protists.

Classification

Monadofilosa includes the testaceans, which are testate filose amoeboids, and the cercomonads.

It is sometimes described as Testaceafilosia and Sarcomonadea.[2]

It has also been described as Sarcomonadea (Cercomonas, Heteromita, Bodomorpha, Proleptomonas, Allantion), Thecofilosea (Cryptodifflugia, Cryothecomonas), Spongomonadea (Spongomonas, Rhipidodendron), and Imbricatea (Thaumatomonas, Thaumatomastix, Allas, Gyromitus, Euglypha, Trinema, Paulinella).[3]

Monadofilosa is sometimes treated as a superclass rather than a subphylum.

Sainouron has been grouped in Monadofilosa.[4]
