Miliolana is a subclass established by Saidova, 1981 that comprises porcelaneous members of the Miliolata from the Cornuspirida, Miliolida with agglutinated forms removed to the Miliamminana, and Soritida. Included are both free and attached forms, some coiled with two chambers per whorl arranged in different planes, others that are irregular or have serial chambers, and still others are fusiform with complex interiors, superficially resembling the Fusulinacea. The unifying character is their imperforate porcelaneous tests.

The oligotrichs are a group of ciliates, included among the spirotrichs. They have prominent oral cilia, which are arranged as a collar and lapel, in contrast to the choreotrichs where they form a complete circle. The body cilia are reduced to a girdle and ventral cilia. In Halteria and its relatives, they form bristles or cirri; however these forms may be closer relatives of the stichotrichs than of other oligotrichs. These organisms are very common in plankton communities, especially in marine systems. Usually found in concentrations of about 1 per ml, they are the most important herbivores in the sea, the first link in the food chain.

The alveolates (meaning "with cavities")[2] are a group of protists, considered a major clade[3] and superphylum[4]within Eukarya, and are also called Alveolata.[5]
The most notable shared characteristic is the presence of cortical (outer-region) alveoli (sacs). These are flattened vesicles (sacs) packed into a continuous layer just under the membrane and supporting it, typically forming a flexible pellicle (thin skin). In dinoflagellates they often form armor plates. Alveolates have mitochondria with tubular cristae (ridges), and their flagellae or cilia have a distinct structure.
Almost all sequenced mitochondrial genomes of ciliates and apicomplexia are linear.[6] The mitochondrial genome of Babesia microti is circular.[7] This species is also now known not to belong to either of the genera Babesia or Theileria and a new genus will have to be created for it.
Alveolata comprises around 9 major and minor groups, which are very diverse in form, and are known to be related by various ultrastructural and genetic similarities:[8]
- Ciliates – very common protozoa with many short cilia arranged in rows, and two nuclei
- Acavomonidia[8]
- Colponemidia[8]
- Dinoflagellates s.l. – mostly marine flagellates many of which have chloroplasts
- Perkinsozoa
- Chromerida – a marine phylum of photosynthetic protozoa
- Colpodellida
- Voromonadida
- Apicomplexa – parasitic and secondary non-photosynthetic protozoa that lack axonemal locomotive structures except in gametes
The Acavomonidia and Colponemidia were previously grouped together as colponemids, a taxon now split based on ultrastructural analysis. The Acavomonidia are closer to the dinoflagellate/perkinsid group than the Colponemidia are.[8] As such, the informal term "colponemids", as it stands currently, covers two non-sister groups within Alveolata: the Acavomonidia and the Colponemidia.[8]
The Apicomplexa and dinoflagellates may be more closely related to each other than to the ciliates. Both have plastids, and most share a bundle or cone of microtubules at the top of the cell. In apicomplexans this forms part of a complex used to enter host cells, while in some colorless dinoflagellates it forms a peduncle used to ingest prey. Various other genera are closely related to these two groups, mostly flagellates with a similar apical structure. These include free-living members in Oxyrrhis and Colponema, and parasites in Perkinsus,[9] Parvilucifera, Rastrimonas and the ellobiopsids. In 2001, direct amplification of the rRNA gene in marine picoplankton samples revealed the presence of two novel alveolate linages, called group I and II.[10][11] Group I has no cultivated relatives, while group II is related to the dinoflagellate parasite Amoebophrya, which was classified until now in the Syndinialesdinoflagellate order.
Relationships between some of these major groups were suggested during the 1980s, and a specific relationship between all three was confirmed in the early 1990s by genetic studies, most notably by Gajadhar et al.[12] Cavalier-Smith introduced the formal name Alveolata in 1991,[5] although at the time he actually considered the grouping to be a paraphyletic assemblage, rather than a monophyletic group.
Some studies suggested the haplosporids, mostly parasites of marine invertebrates, might belong here, but they lack alveoli and are now placed among the Cercozoa.

The development of plastids among the alveolates is intriguing. Cavalier-Smith proposed the alveolates developed from a chloroplast-containing ancestor, which also gave rise to the Chromista (the chromalveolate hypothesis). Other researchers have speculated that the alveolates originally lacked plastids and possibly the dinoflagellates and Apicomplexa acquired them separately. However, it now appears that the alveolates, the dinoflagellates, the Chromerida and the heterokont algae acquired their plastids from a red alga with evidence of a common origin of this organelle in all these four clades.[16]
A Bayesian estimate places the evolution of the alveolate group at ~850 million years ago.[17] The Alveolata consist of Myzozoa, Ciliates, and Colponemids. In other words, the term Myzozoa, meaning "to siphon the contents from prey", may be applied informally to the common ancestor of the subset of alveolates that are neither ciliates nor colponemids. Predation upon algae is an important driver in alveolate evolution, as it can provide sources for endosymbiosis of novel plastids. The term Myzozoa is therefore a handy concept for tracking the history of the alveolate phylum.
The ancestors of the alveolate group may have been photosynthetic.[18] The ancestral alveolate probably possessed a plastid. Chromerids, apicomplexans, and peridinin dinoflagellates have retained this organelle.[19] Going one step even further back, the chromerids, the peridinin dinoflagellates and the heterokont algae possess a monophyletic plastid lineage in common, i.e. acquired their plastids from a red alga,[16] and so it seems likely that the common ancestor of alveolates and heterokonts was also photosynthetic.
In one school of thought the common ancestor of the dinoflagellates, apicomplexans, Colpodella, Chromerida, and Voromonas was a myzocytotic predator with two heterodynamic flagella, micropores, trichocysts, rhoptries, micronemes, a polar ring and a coiled open sided conoid.[20] While the common ancestor of alveolates may also have possessed some of these characteristics, it has been argued that Myzocytosis was not one of these characteristics, as ciliates ingest prey by a different mechanism.[8]
An ongoing debate concerns the number of membranes surrounding the plastid across apicomplexans and certain dinoflagellates, and the origin of these membranes. This ultrastructural character can be used to group organisms and if the character is in common, it can imply that phyla had a common photosynthetic ancestor. On the basis that apicomplexans possess a plastid surrounded by 4 membranes, and that peridinin dinoflagellates possess a plastid surrounded by 3 membranes, Petersen et al.[21] have been unable to rule out that the shared stramenopile-alveolate plastid could have been recycled multiple times in the alveolate phylum, the source being stramenopile-alveolate donors, through the mechanism of ingestion and endosymbiosis.
Ciliates are a model alveolate, having been genetically studied in great depth over the longest period of any alveolate lineage. They are unusual among eukaryotes in that reproduction involves a micronucleus and a macronucleus. Their reproduction is easily studied in the lab, and made them a model eukaryote historically. Being entirely predatory and lacking any remnant plastid, their development as a phylum illustrates how predation and autotrophy[18]are in dynamic balance and that the balance can swing one way or other at the point of origin of a new phylum from mixotrophic ancestors, causing one ability to be lost.

This genus infects the flour beetle Tribolium castaneum.
The sporozoites enter the host by the oral route, usually by ingestion of contaminated food but also by cannibalism of an infected host.
Infection with this genus increases larval mortality and interferes with normal development.

Machadoella is a genus of parasitic alveolates in the phylum Apicomplexa.
Species in this genus infect species of the family Reduviidae.
This genus was created by Reichenow in 1935.[1]
The type species - Machadoella spinigeri - was first described by Machado in 1913.
The species in this genus develop in the Malphigian tubules of their host.
The trophozoites are worm like with longitudinal folds.
The schizonts are globular with multiple nuclei.
The gamonts are elongated and slightly swollen at the level of the nucleus.
Syzygy occurs at the anterior end of the gamonts.
The gametes are similar in size (isogamy).
The spores are fusiform (lemon shaped).

Syncystis is a genus of parasitic alveolates in the phylum Apicomplexa.
Species in this family infect insects (Aeshnidae).
This genus was described by Schneider in 1886.
Two species are currently recognised in this family.[1]
The type species is Syncystis mirabilis Schneider 1886.
The development of these parasites is mostly intracellular. Merogony results in the formation of about 150 elongate, slender merozoites which become spheroidal as they differentiate into amoeboid or spheroidal gamonts.
The gamonts associate in syzygy and subdivide into gametes.
Fusion of the gametes leads to numerous zygotes within the gametocyst which is either spherical or bilobed.
Numerous (30 to 150) oocysts are formed per gametocyst. The oocysts are navicular and have three or four spines extending from each pole of the wall.
Eight sporozoites form per oocyst.

The Archaeplastida+HC+SAR megagroup is a group of eukaryotes proposed by Burki et al. (2008).[1] It is also referred to as Diaphoretickes (/ˌdaɪəfəˈrɛtɪkiːz/) or the SAR/HA Supergroup, or the Corticata with Rhizaria.[2]
It includes:
- Archaeplastida (comprising the plants, red algae, green algae, and glaucophytes)
- Hacrobia (the "HC" refers to Haptista and Cryptista, the two basal clades in the group)
- SAR supergroup (consisting of stramenopiles+alveolates+Rhizaria)
According to this description, it includes most of the species engaging in photosynthesis, except for the Euglenozoa and Cyanobacteria. It includes all Bikonts that are not excavates and Hemimastigophora.
The name "Corticata" comes from Cavalier-Smith's hypothesis about the common origin of the cortical alveoli of glaucophytes and alveolates.[3]
The megagroup was previously described as the sum of Archaeplastida, Rhizaria, and chromalveolates.[4]However, this description is obsolete, largely due to the discovery that chromalveolata is not monophyletic.
https://en.wikipedia.org/wiki/Plants%2BHC%2BSAR_megagroup
SAR or Harosa (informally the SAR supergroup) is a clade that includes stramenopiles (heterokonts), alveolates, and Rhizaria.[2][3][4][5] The name is an acronym derived from the first letters of each of these clades; it has been alternatively spelled "RAS".[6][7] The term "Harosa" (at the subkingdom level) has also been used.[8] The SAR supergroup was formulated as the node-based taxon[6].
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.[9] This apparently excluded haptophytes and cryptomonads, leading Okamoto et al. (2009) to propose the clade Hacrobia to accommodate them.[10]
https://en.wikipedia.org/wiki/SAR_supergroup
The Archaeplastida (or kingdom Plantae sensu lato) are a major group of eukaryotes, comprising the photoautotrophic red algae (Rhodophyta), green algae, land plants, and the minor group glaucophytes.[4] It also includes the non-photosynthetic lineage Rhodelphidia, a predatorial (eukaryotrophic) flagellate that is sister to the Rhodophyta, and probably the microscopic picozoans.[5] The Archaeplastida have chloroplaststhat are surrounded by two membranes, suggesting that they were acquired directly through a single endosymbiosis event by feeding on a cyanobacterium.[6] All other groups which have chloroplasts, besides the amoeboid genus Paulinella, have chloroplasts surrounded by three or four membranes, suggesting they were acquired secondarily from red or green algae.[note 1] Unlike red and green algae, glaucophytes have never been involved in secondary endosymbiosis events.[8]
