  Metamonad
The metamonads are a large group of flagellate protozoa.
Their composition is not entirely settled, but they include the retortamonads, diplomonads, and possibly the parabasalids and oxymonads as well.
The metamonads make up part of the excavates, a eukaryotic supergroup including flagellates with feeding grooves and their close relatives.

Trimastix The metamonads are a group of flagellate protozoa, including the retortamonads, diplomonads, and possibly the parabasalids and oxymonads as well.
These four groups are all anaerobic, lacking mitochondria, and are mostly found as symbiotes of animals.
However, all are now known to have lost mitochondria secondarily, and metamonads retain both organelles and nuclear genes derived from them.

 Trichonympha - EvoWiki
Trichonympha is a genus of metamonad protists (relatives of the infamous Giardia parasites) that live in the intestines of many, if not most, termite species.
They are important symbiotes, in that they break down the cellulose in the wood and plant fibers their hosts eat.
They are extremely motile, and feed by engulfing wood and plant fibers through phagocytosis, which always occurs at the broad ends of their bodies.

Of these, the Heterolobosea and Euglenozoa appear to be particularly close relatives, united by the presence of discoid cristae within their mitochondria, rather than tubular cristae.
However, their exact relationships are still uncertain, and it is possible that the metamonads and jakobids are not monophyletic groups.
The excavates are often considered among the most primitive eukaryotes, and may be paraphyletic to the others.

Termites cannot themselves digest the wood that they consume.
Instead they rely upon symbiotic protozoans (metamonads) in their intestines to digest the cellulose for them, absorbing the end products for their own use.
These protozoans in turn rely on symbiotic bacteria to produce the necessary enzymes.

 Parabasalid - Wikipedia, the free encyclopedia
Parabasalids are anaerobic, and lack mitochondria, but this is now known to be a result of secondary loss, and they contain small hydrogenosomes which apparently developed from reduced mitochondria.
Similar relics have been found in other amitochondriate flagellates, and the parabasalids are probably related to them, forming a group called the metamonads.
They lack the feeding grooves found in most others, but this is probably a secondary loss as well.

The excavates may be among the most ancient of living eukaryotes.
The jakobids, especially Reclinomonas americana, have the most eubacterial-like mitochondrial genomes of any eukaryotes that have been studied, while metamonads such as Giardia lack many of the cell structures ("organelles"), including mitochondria, that are considered typical for eukaryotic cells.

Cellulose is a rich energy source (think of wood fires), but difficult to digest.
Termites rely primarily upon symbiotic protozoa (metamonad s) called trichonympha and other microbe s in their gut to digest the cellulose for them, absorbing the end products for their own use.
The gut protozoa in turn rely on symbiotic bacterium embedded on their surfaces to produce some of the necessary digestive enzymes.

If we assume these groupings are correct, then we can suggest plausible gene transfer scenarios.
For instance, the type II GPI of diplomonads and parabasalids is explained by a gene transfer event in their common 'metamonad' ancestor, while all other eukaryotes acquired their type I GPI homologs in one (or possibly two) separate event from a eubacterial donor (Additional file 2).
On the other hand, the FBA tree suggests a common ancestor of diplomonads and Trimastix inherited an LGT of the class II type B enzyme to the exclusion of parabasalids (Fig.
