Taxonomy
The Subphylum Intramacronucleata is a member of the Phylum Ciliophora. Here is the complete "parentage" of Intramacronucleata:
- Domain: Eukaryota
Whittaker & Margulis,1978 - eukaryotes
- Kingdom: Protozoa
(Goldfuss, 1818) R. Owen, 1858
- Subkingdom: Biciliata
- Infrakingdom: Alveolata
Cavalier-Smith, 1991
- Phylum: Ciliophora
(Doflein, 1901) Copeland, 1956 - Ciliates
- Subphylum: Intramacronucleata Lynn, 1996
- Phylum: Ciliophora
(Doflein, 1901) Copeland, 1956 - Ciliates
- Infrakingdom: Alveolata
Cavalier-Smith, 1991
- Subkingdom: Biciliata
- Kingdom: Protozoa
(Goldfuss, 1818) R. Owen, 1858
The Subphylum Intramacronucleata is further organized into finer groupings including:
- Infraphylum (1): Atelocerata
- Superclass (1): Panhexapoda
- Class (8): Colpodea · Litostomatea · Nassophorea · Oligohymenophorea · Phyllopharyngea · Plagiopylea · Prostomatea · Spirotrichea
Classes
Colpodea

Litostomatea
The Litostomatea are a class of protozoa, divided into two groups, ranked as subclasses. The Haptoria includes mostly carnivorous forms, for instance Didinium, a species of which preys exclusively on the ciliate Paramecium. The Trichostomatia (trichostomes) are mostly endosymbionts in the digestive tracts of vertebrates. These include the species Balantidium coli, which is the only ciliate parasitic in humans. [more]
Nassophorea
Oligohymenophorea
The Oligohymenophorea are a large class of protozoa. There is typically a ventral groove containing the mouth and distinct oral cilia, separate from those of the body. These include a paroral membrane to the right of the mouth and membranelles, usually three in number, to its left. The cytopharynx is inconspicuous and never forms the complex cyrtos found in similar classes. Body cilia generally arise from monokinetids, with dikinetids occurring in limited distribution over part of the body. [more]
Phyllopharyngea
Plagiopylea
Prostomatea
Spirotrichea
The spirotrichs are a large and distinctive group of protozoa. They typically have prominent oral cilia in the form of a series of polykinetids, called the adoral zone of membranelles, beginning anterior to the oral cavity and running down to the left side of the mouth. There may also be one or two paroral membranes on its right side. The body cilia are fused to form polykinetids called cirri in some, and are sparse to absent in others. [more]
At least 106 species and subspecies belong to the Class Spirotrichea.
