• Dientamoeba Jepps, M. & Dobell, C. 1918. A study of the diverse races of Entamoeba histolytica distinguishable from one another by dimensions of their cysts. Parasitology 10: 320–351.

Introduction

[These small binucleate amoebae have been shown ultrastructurally to have trichomonad flagellate affinities due to the presence of a parabasal apparatus (basal body and axostyle lacking), a paradesmosome as part of an extranuclear spindle originating from attractophores, and hydrogenosomes (modified mitochondria?). They have, therefore, been transferred to the Subfamily Dientamoebinae Grasse in the family Monocercomonadidae Kirby, 1944 in the order Trichomonadida Kirby, 1947 in the class Hypermastigia (Graasi, 1911) [= Cristamonadea Brugerolle & Patterson, 2001] in the phylum Parabasalia Honigberg, 1973].
