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]
- The testaceans live both in marine and freshwater habitats, and in mosses. Members include Lecythium, Pseudodifflugia, Euglypha (a euglyphid), and Paulinella chromatophora.
- Cercomonads are flagellates that glide on their posterior cilium and/or generate filopodia. Members of this group contain Cryothecomonas, Thaumatomonas, which is covered with siliceous scales, and Cercomonas, which is nake. Cercomonas contains several species that show exhibit amoeboid movement, such as the testate amoeba Cyphoderia, and the flagellate Cryothecomonas.
Monadofilosa is sometimes treated as a superclass rather than a subphylum.
Sainouron has been grouped in Monadofilosa.[4]
