Malawimonas Jakobiformis
''Malawimonas'' is a Loukozoa genus, possible sister of the Podiata. History of the discovery of Malawimonads In 1993, Charles J O’ Kelly studied the jakobid groups flagellates and implications for the early diversification of eukaryotes and recognized that ''Jakoba, Reclimonas,'' and ''Histonia'' or often refer as “core jakobids” were morphologically somewhat similar. Interestingly, they included an unnamed and undescribed free-swimming, flagellate, and also groove- bearing cell. During the early study, these cells were thought to be a member from ''Jakoba'' due to the external morphology features that resembles ''Jakoba libera'' in terms of lack of cell covering, sessile trophic stages, swimming in a similar manner and sharing the tendency for the anterior flagellum to form a “crook. However, later discovery found that this species seems to not fit and can not be assigned to the genus ''Jakoba'', nor to any other genus of Jakobids, because of their discoidal mitochond ...

Eukaryota
Eukaryotes () are organisms whose cells have a nucleus. All animals, plants, fungi, and many unicellular organisms, are Eukaryotes. They belong to the group of organisms Eukaryota or Eukarya, which is one of the three domains of life. Bacteria and Archaea (both prokaryotes) make up the other two domains. The eukaryotes are usually now regarded as having emerged in the Archaea or as a sister of the Asgard archaea. This implies that there are only two domains of life, Bacteria and Archaea, with eukaryotes incorporated among archaea. Eukaryotes represent a small minority of the number of organisms, but, due to their generally much larger size, their collective global biomass is estimated to be about equal to that of prokaryotes. Eukaryotes emerged approximately 2.3–1.8 billion years ago, during the Proterozoic eon, likely as flagellated phagotrophs. Their name comes from the Greek εὖ (''eu'', "well" or "good") and κάρυον (''karyon'', "nut" or "kernel"). E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scotokaryota
The Scotokaryotes (Cavalier-Smith) is a proposed basal Neokaryote clade as sister of the Diaphoretickes. Basal Scotokaryote groupings are the Metamonads, the Malawimonas and the Podiata. In this phylogeny the Discoba are sometimes seen as paraphyletic and basal Eukaryotes. An alternative to the Unikont–Bikont division was suggested by Derelle ''et al.'' in 2015, where they proposed the acronym An acronym is a word or name formed from the initial components of a longer name or phrase. Acronyms are usually formed from the initial letters of words, as in ''NATO'' (''North Atlantic Treaty Organization''), but sometimes use syllables, as ...s Opimoda–Diphoda respectively, as substitutes to the older terms. The name Opimoda is formed from the letters (shown in capitals) of OPIsthokonta and aMOebozoa. In this phylogeny Discoba belongs to the Diphoda clade.

CRuMs
CRuMs is a proposed clade of microbial eukaryotes, whose name is an acronym of the following constituent groups: i) collodictyonids also known as diphylleids, ii) rigifilids Rigifilida is a clade of non- ciliate phagotrophic eukaryotes. It consists of two genera: '' Micronuclearia'' and ''Rigifila''. Characteristics Cells of rigifilids are covered with either a single or a double-layered submembrane pellicular lam ... and iii) mantamonadids as sister of the Amorphea. It more or less supersedes Varisulca, as Ancyromonadida are inferred not to be specifically related to the orders Collodictyonida, Rigifilida and Mantamonadida.

Collodictyonidae
Collodictyonidae (also Diphylleidae) is a group of aquatic, unicellular eukaryotic organisms with two to four terminal flagella. They feed by phagocytosis, ingesting other unicellular organisms like algae and bacteria. The most remarkable fact of this clade is its uncertain position in the tree of life. Recent molecular analyses place Collodictyonids (e.g. Collodictyon) in a clade also containing Rigifilida and Mantamonadidae. This clade has been named CRuMs and is sister to Amorphea.

Rigifilida
Rigifilida is a clade of non-ciliate phagotrophic eukaryotes. It consists of two genera: ''Micronuclearia'' and ''Rigifila''. Characteristics Cells of rigifilids are covered with either a single or a double-layered submembrane pellicular lamina that makes them rigid in consistence. Slender branching filopodia emanate from a ventral aperture of the cell and are employed to collect bacteria upon which they feed and to attach the organism to the substratum. Around this aperture, the pellicle is reflexed around forming a peristomial collar. Other notable features are flat and irregular shaped mitocondrial cristae, a single dorsal nucleus and the lack of centrioles and cilia. Phylogeny Taxonomy Rigifilida is currently placed in CRuMs. *Order Rigifilida Cavalier-Smith 2012 icronucleariida Cavalier-Smith 2008** Family Rigifilidae Yabuki & Cavalier-Smith 2012 *** Genus ''Rigifila'' Yabuki & Cavalier-Smith 2012 **** Species ''Rigifila ramosa'' Yabuki & Cavalier-Smith 2012 ** Famil ...
