Description
Members of this taxon are characterized by having, ancestrally, a ventral cytopharynx,[1] as the name suggests.
Phylogeny
The monophyly of CONthreeP is well supported, being placed as sister to Protocruziea.[2] The order Discotrichida, belonging to class Nassophorea, has been recovered as the earliest branch of the clade.[2]
