CLASS TRYPANOSOMEA
Cells with specialized mitochondrion, which contains a kinetoplast (k-DNA).
- ORDER BODONIDA.
- Two heterodynamic flagella (text with tooltip) Heterodynamic flagella occur on the same cell but beat with different patterns (e.g. anterior-posterior). usually present, whiplash flagellum trailing and tinsel flagellum directed anteriorly or laterally; flagella emerge from a shallow pocket; with a well-formed cytostome; kinetoplast large and single, sometimes dispersed throughout the mitochondrion; free-living and parasitic.
- Bodo, Pleuromonas, Rhynchomonas, Proteromonas, Phyllomitus, Colponema
- ORDER TRYPANOSOMIDA.
- One flagellum which emerges from a deep flagellar pocket, often attached to the pellicle as an undulating membrane, sometimes free; a second, barren basal body (text with tooltip) Basal body with no associated flagellum. usually present; kinetoplast small and compact; parasitic in animals and plants.
- Trypanosoma, Crithidia, Leptomonas, Phytomonas, Herpetomonas, Leishmania.
CLASS POSTGAARDEA
Mitochondria without kinetoplast or cristae. The class has a single order: POSTGAARDIDA.
- Postgaardi, Calkinsia.
