Classes [1] | |
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]
Members of this taxon are characterized by having, ancestrally, a ventral cytopharynx, [1] as the name suggests.
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]
