Description :

Microjoenia are relatively small spirotrichonymphid flagellates (5 to 20 µm) with flagella arising around an apical bare pole and deflected posteriorly. Seven to 15 longitudinal or oblique flagellar lines at the anterior part of the cell. Parabasal bodies arranged in a crown around the anterior pole and the nucleus, tube-like axostylar trunk protruding posteriorly. Cytoplasm filled with wood particles, occurring in termites. Microjoenia anterodepressa Brugerolle, 2000 from Porotermes grandis is a pear-shaped flagellate with an average size 20 µm long and 10 µm broad and a charactristic depressed bare apical pole above the large nucleus. Generally five spiralled flagellar bands, axostyle protruding posteriorly, three to four Golgi bodies immediately posterior to the nucleus. Giemsa stain.
