Trimitus Alexeieff

genus / DIPLOMONADIDA / ENTEROMONADIDAE

Description

Very small flagellate (3-8 ~m) with similar characters to Enteromonas; however, it has only 2 ante rior flagella and a recurrent one associated with the ventral ridge extending to the posterior extremity (Fig . 4b). The 4 species described I ive in the intestine of fishes (Aiexeieff , 1 91 0) , frogs , tortoises , insects (Perez-Reyes , 1 9 6 4) , and snake . Electron microscopic study of flagellates assigned to the genus Trimitus (Brugerolle , 1986) has shown they have the characters of Enteromonadidae and differ from the tiny Tricercomitus which are ·trichomonads . The recurrent flagellum is adherent to the ventral ridge, which shows ultrastructural differences with that of Enteromonas. However, 4 basal bodies and flagella are present suggesting either a and confusion with Enteromonas species or an erroneous light microscopic description of the iardia genus Trimitus.

2 ante rior flagella and a recurrent one associated
with the ventral ridge extending to the posterior
extremity (Fig . 4b). The 4 species described I ive

flagellates assigned to the genus Trimitus

recurrent flagellum is adherent to the ventral
