Etude ultrastructurale de Troglodytella gorillae, cilié de l'intestin des gorilles: Considérations sur la systématique des ciliés entodiniomorphes

This ultrastructural study of the entodiniomorphid Troglodytella gorillae provides information on the constitution of the cortex, which is composed of the plasma membrane, a thick epiplasm, microtubules, and a microfibrillar ecto-endoplasmic limit (cortex type I). This observation allows us to group the family Troglodytellidae with the families Cycloposthiidae and Ophryoscolecidae. These 3 families should be separated from the families Tripalmariidae and Spirodiniidae which possess a more complex cortex, with longitudinal dense tracts inserted between the microtubular layer and the microfibrillar ecto-endoplasmic limit (type II). Terminology is discussed.
