HIERARCHICAL CLASSIFICATION OF THE PHYLUM JAKOBADA (CAVALIER-SMITH 1993)
| EUKARYA> EXCAVATA> EUEXCAVATA> JAKOBADA |
JAKOBADA LINKS
| The general organization of the following taxonomy was influenced by Patterson (1999), Cavalier-Smith (2003a and 2003b), Simpson (2003), and Taylor (1999). |
CLASS JAKOBEA
- Cells isokont; posterior flagellum with ventral vane; mitochondria with flat or tubular cristae. Cells may be naked and free-swimming or attached and loricate. This class has a single order: JAKOBIDA.
- Jakoba, Reclinomonas, Histonia.
CLASS MALAWIMONADEA
- Cells anisokont; posterior flagellum with dorsal vane. Mitochondria with discoid cristae. Anaerobic. This class has a single order: MALAWIMONADIDA.
- Malawimonas.
