Stomatophorinae
The Stomatophorinae are a subfamily of parasites in the phylum Apicomplexa. Taxonomy There are ten genera in this subfamily: ''Albertisella'', ''Arborocystis'', ''Astrocystella'', ''Beccaricystis'', ''Chakravartiella'', ''Choanocystoides'', ''Craterocystis'', ''Parachoanocystoides'', ''Stomatophora'' and ''Zeylanocystis''. History This subfamily was created by Bhatia in 1930.Bhatia BL (1930) Synopsis of the genera and classification of haplocyte gregarines.

Monocystidae
The Monocystidae are a family of parasitic alveolates in the phylum Apicomplexa. Taxonomy There are five subfamilies in this family: ''Monocystinae'', ''Oligochaetocystinae'', ''Rhynchocystinae'', ''Stomatophorinae'' and ''Zygocystinae''. History This family was created by Bütschli in 1882.Bütschli O, Schwager C (1882) Protozoa. Abt. 1, Sarkodina und Sporozoa. Leipzig: F. C. Wintersche Verlagshandlung Description The hosts of the species in this family are usually oligochaetes. The species in this family generally infect the coelom of their hosts. The gamonts are spherical to cylindrical. The anterior end is little differentiated if at all. The oocyst Apicomplexans, a group of intracellular parasites, have life cycle stages that allow them to survive the wide variety of environments they are exposed to during their complex life cycle. Each stage in the life cycle of an apicomplexan organism i ...s are biconical or boat-shaped. References Apicomplexa families ...

Eukaryota
Eukaryotes () are organisms whose Cell (biology), cells have a cell nucleus, 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-domain system, 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), Asgard archaea. This implies that there are only Two-domain system, 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 (ecology), 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 cell, flagellated phagotrophs. The ...

SAR Supergroup
The SAR supergroup, also just SAR or Harosa, is a clade that includes stramenopiles (heterokonts), alveolates, and Rhizaria. The name is an acronym derived from the first letters of each of these clades; it has been alternatively spelled "RAS". The term "Harosa" (at the subkingdom level) has also been used. The SAR supergroup is a node-based taxon. Note that as a formal taxon, "Sar" has only its first letter capitalized, while the earlier abbreviation, SAR, retains all uppercase letters. Both names refer to the same group of organisms, unless further taxonomic revisions deem otherwise. Members of the SAR supergroup were once included under the separate supergroups Chromalveolata (Chromista and Alveolata) and Rhizaria, until phylogenetic studies confirmed that stramenopiles and alveolates diverged with Rhizaria. This apparently excluded haptophytes and cryptomonads, leading Okamoto ''et al.'' (2009) to propose the clade Hacrobia to accommodate them. Phylogeny Based on a compi ...
