Pronunciation: ep′i-mas′ti-gōt

Definition: An insect stage of Trypanosomatide infection. Term replacing “crithidial stage,” to avoid confusion with the insect-parasitizing flagellates of the genus Crithidia. In the epimastigote stage, the flagellum arises from the kinetoplast alongside the nucleus and emerges from the anterior end of the organism; an undulating membrane is present.

[epi- + G. mastix, whip]
