AmphitrematidaeEdward Mitchell and Ralf Meisterfeld
This tree diagram shows the relationships between several groups of organisms.
The root of the current tree connects the organisms featured in this tree to their containing group and the rest of the Tree of Life. The basal branching point in the tree represents the ancestor of the other groups in the tree. This ancestor diversified over time into several descendent subgroups, which are represented as internal nodes and terminal taxa to the right.
You can click on the root to travel down the Tree of Life all the way to the root of all Life, and you can click on the names of descendent subgroups to travel up the Tree of Life all the way to individual species.close box
The position of the Amphitrematidae is currently uncertain. Due to an error by De Saedeleer (1934) this family has been sometimes included with the Granuloreticulosea, but there is no doubt that Amphitrema and Archerella have filopodia (cf. images).

The pseudopodia of Paramphitrema differ significantly, and it is unclear whether the presence of two apertures is sufficient to place this genus in the Amphitremidae.
Diplophrys and Microcometes have previously been included in this area but Diplophrys has since been shown to have affinities with the Labyrinthulids (Dykstra & Porter, 1984) and Microcometes is a flagellate.
