Relationships among 59 genera and species were determined by analyzing 122 ultrastructural, morphological stomatogenic, nuclear and asexual reproductive features on the basis of a numerical phenetic analysis. The study concerned 12 genera and species of the colpodid group. The same procedure was used for the analysis of 47 kinetophragminophoran, oligohymenophoran, polyhymenophoran genera. A new macrosystem of the phylum Ciliophora is shown. Three subphyla are distinguished: Karyorelictophora with 1 class. Karyorelictea; Kinetophragmophora with 4 classes, Colpodea, Hypostomea including Peniculida, Nassulida, Parapeniculida and Peritrichida, Spirotrichea including Hypotrichida, Clevelandellida, Heterotrichida and Oligotrichida and Hymenostomea including Hymenostomatida and Apostomatida; Hymenophora with 2 classes, Phyllopharyngea and Gymnostomea including 2 subclasses, Gymnostomia and Astomia.
