03CD87847359FFB386BE3BA00F76F8DE.taxon	discussion	Preptychostomum ciliates are usually globular in shape. They are characterized by a large oral cavity, an anterior bare area more or less developed without skeletal fibers. The elongated macronucleus perpendicular to the anteroposterior axis of the cell is surmounted by a bulky micronucleus. There is the presence of a posterior pulsatile vacuole. In the genus Preptychostomum, we describe a new species: P. donedaensis n. sp.	en	Nana, Paul Alain, Tchakonte, Simeon, Mama, Anselme Crepin, Onana, Fils Mamert, Fokam, Zephyrin, Ngassam, Pierre, Masseret, Estelle, Nola, Moïse, Sime-Ngando, Telesphore (2022): Four new species of Hysterocinetida (Protozoa: Ciliophora) from the digestive tract of earthworms collected to the lower Nyong estuary (South Coast, Cameroon).
