It denotes the stage (ineffective stage for South American trypanosomiasis and African trypanosomiasis, and the only stage found in humans in the latter illness) in which the flagellum arises from a posteriorly located kinetoplast and emerges from the side of the body, with an undulating membrane running along the length of the body.
