Belongs within: Kinetoplastea.
The Trypanosomatida are a group of micro-organisms parasitic on vertebrates, some of which are known for causing serious diseases. The African species T. brucei causes sleeping sickness in humans and nagana in cattle.
Characters (from Adl et al. 2012): Eukinetoplastic with kDNA network associated with ciliary basal body; uniciliated with cilium lacking hairs and emerging from anterior pocket, or emerging laterally and attached to body; phagotrophic or osmotrophic; cytostome, when present, simple and close to ciliary pocket; exclusively parasitic.
