Description:

Joenia (joe-een-ee-a) is a lophomonad hypermastigid flagellate - this group being distinguished by having a pad of very long flagella inserting to one side of the anterior apex of the cell. The lophomonads are a subset of the trichomonad flagellates, and the trichomonad beat profile is evident in this image. There is a very substantial axostyle, forming a calyx or sheath that envelopes the nucleus and the flagellar area, and projecting from the back of the cell. From the termite Kalotermes. Phase contrast.
