Hexamastix dobelli n. sp. (Trichomonadidae) is described from the large intestine of the starred tortoise, Testu‐do elegans Schoepff. This is the first species of Hexamastix to be reported from a chelonian. The organism is pyriform, oval, or round in shape. There are five anterior flagella, of which two are long and three short and a single recurrent flagellum, which equals the short anterior flagella in length. The axostyle is very slender and projects for some distance outside the body. The nucleus contains three to six granules and has no endosome. The pelta is crescent‐shaped and the parabasal body is rod‐like. Perinuclear granules are present in the anterior half of the body. The parasite is 6.0 to 16.5 μ long, 2.0 to 10.3 μ wide and the diameter of nucleus is 2.5 μ.
