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

A protist () is any eukaryotic organism (that is, an organism whose cells contain a cell nucleus) that is not an animal, plant, or fungus. While it is likely that protists share a common ancestor (the last eukaryotic common ancestor), the exc ...

Classification
Monadofilosa includes the
testaceans, which are testate filose
amoeboid
An amoeba (; less commonly spelled ameba or amœba; plural ''am(o)ebas'' or ''am(o)ebae'' ), often called an amoeboid, is a type of cell or unicellular organism with the ability to alter its shape, primarily by extending and retracting pseudopo ...
s, and the
cercomonad
Cercomonads are small flagellates, widespread in aqueous habitats and common in soils.
Characteristics
The cells are generally around 10 μm in length, without any shell or covering. They produce filose pseudopods to capture bacteria, but do n ...

It is sometimes described as Testaceafilosia and Sarcomonadea.
It has also been described as
Sarcomonadea
The sarcomonads () or class Sarcomonadea are a group of amoeboid biciliate protists in the phylum Cercozoa. They are characterized by a propensity to move through gliding on their posterior cilium or through filopodia, a lack of scales or ext ...
