DescriptionFamily
Malawimonadidae O'Kelly & Nerad (1999,
p. 529).
Malawimonadidae fam. nov. Free-living heterotrophic nanoflagellate
protists with apical insertion of flagella. Flagellate cells
uninucleate, mitochondriate. Mitochondria with discoidal
cristae. Golgi of few cisternae, adjacent to flagellar
insertion. Flagella two, the posteriorly directed flagellum lying in
a groove on the ventral surface of the flagellate cell but never
physically attached to the cell body. Posterior flagellum bearing a
vane originating on the ventral side of the flagellum. Kinetid of
interphase cells consisting primarily of two basal bodies and four
microtubular roots, with three of the roots originating in the
vicinity of the posterior basal bodies and defining the ventral
groove. Cysts with a wall formed on the outside of encysting cells
and apparently composed of organic materials; kinetid elements
preserved in mature cysts. With one genus, Malawimonas.
