Popis: Summary The four described species of Ciliates Hysterocinetidae are commensal of the digestive tract of Alma nilotica (Oligochaete Glossoscolecidae, from Cameroons). They have in common a sucker with two posterior lips separated by a space in which anterior extremities of a few somatic kinetics enter. The sucker is devoid of cytoskeletal fibers. Three species are new, two of which belong to the new genus Amieta ( A. prolifera, A. rotundus ); the third belongs to the genus Thurstonia ( T. almae ). The species T. kaczanowskii is redescribed. The genus Amieta differs from Thurstonia in its ovoid shape, symmetrical aspect of the sucker and transversal position of the macronucleus.
