Ventrata is an infraphylum of ciliates inside the subphylum Intramacronucleata that unites the classes Phyllopharyngea, Colpodea, Nassophorea, Prostomatea, Plagiopylea and Oligohymenophorea.[1] It is equivalent to the clade CONthreeP or Conthreep recovered by phylogenetic analyses.[2]

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]
