Hemimastigote
Hemimastigophora is a group of single-celled eukaryotic organisms including the Spironematellidae, first identified in 1988, and the Paramastigidae. Over the next 30 years, different authors proposed placing these organisms in various branches of the eukaryotes. In 2018 Lax ''et al''. reported the first genetic information for Spironemidae, and suggest that they are from an ancient lineage of eukaryotes which constitute a separate clade from all other eukaryotic kingdoms. It may be related to the Telonemia. History of classification Hemimastigophora was established in 1988 by Foissner ''et al''., as a new phylum with a single family, Spironemidae. Its placement on the eukaryote tree of life was unclear, but the authors suggested that the structure of its pellicle and cell nucleus indicated a close relationship with Euglenozoa. For 30 years after the description of the group, no genetic information was available. During that time, researchers proposed that it should b ...

Hemimastix
Spironematellidae (previously known as Spironemidae) is a family (biology), family of heterotrophic flagellates, in the group Hemimastigophora. They vary in size and shape from the ellipsoid ''Hemimastix amphikineta'' (14 × 7 μm) to the vermiform ''Spironematella terricola'' (43 × 3 μm), and are united by the possession of two rows of Cilium, cilia, called kineties. Phylogenomic analysis shows that Hemimastigophora are a distinct and ancient lineage of Eukaryote, eukaryotic organisms, forming a possible sister clade to the supergroup Diaphoretickes.

Apusozoa
The Apusozoa are a paraphyletic phylum of flagellate eukaryotes. They are usually around 5–20 μm in size, and occur in soils and aquatic habitats, where they feed on bacteria. They are grouped together based on the presence of an organic shell or theca under the dorsal surface of the cell. The name derives from the Ancient Greek words for footless () and animal (). This phylum was defined as containing the Breviata and the Apusomonadida. However, it is viewed as paraphyletic, with the Breviata as more basal. The opisthokonts appear to have emerged as sister of the Apusomonadida. It has been suggested that the Mantamonadida be classified in Apusozoa. The Ancyromonadida appear to be Varisulca, Planomonadida, shifting them possibly more basal than the Amoebozoa, or less basal. While some classification systems have placed Hemimastigida in Apusozoa, 2018 research indicated that hemimastigotes (/Hemimastix/ Spironematellidae) are their own supra-kingdom.

Friedrich Traugott Kützing
Friedrich Traugott Kützing (8 December 1807 in Ritteburg – 9 September 1893) was a German pharmacist, botanist and phycologist. Despite his limited background in regard to higher education, Kützing made significant scientific contributions. In 1833, he demonstrated differences between diatoms and desmids, thus separating the two groups into families of their own. Also, independent of Charles Cagniard-Latour (1777–1859) and Theodor Schwann (1810–1882), he was among the first to provide comprehensive answers in regard to yeast and the role it played in fermentation. In 1849, he published ''Species Algarum'', a large work that provided descriptions for 6000 species of algae. He is the taxonomic authority of the genera '' Syringodium'' (family Cymodoceaceae) and ''Phlebothamnion'' (family Ceramiaceae). Early life As a young man, he worked in several pharmacies in Germany, also serving as assistant for a few semesters at the chemical-pharmaceutical institute of Fran ...

Alastair G
Alistair is a male given name. It is an Anglicised form of the Scottish Gaelic name ''Alasdair''. The latter is most likely a Scottish Gaelic variant of the Norman name Alexandre or the Latin name Alexander, which was incorporated into English in the same form as Alexander. The deepest etymology is the Greek Ἀλέξανδρος (man-repeller): ἀλέξω (repel) + ἀνήρ (man), "the one who repels men", a warrior name. Another (much less common) Anglicisation of ''Alasdair'' is ''Allaster''. Hanks; Hardcastle; Hodges (2006) p. 399.

Meteora Sporadica
''Meteora sporadica'' is a mysterious free-living protozoan discovered in 2002 during sampling at a depth of 1,230 meters below sea level in the Sporades Basin, part of the Mediterranean Sea. So far it is the only species of the genus ''Meteora''. It was placed as Eukaryota ''incertae sedis'' due to its unique morphology unlike any other group of protists. Two decades later, a 2022 phylogenetic analysis of ''Meteora'' still was not able to solidly relate it to any known group of eukaryotes, suggesting that it could be a new high-level eukaryotic group. In 2024 it was revealed to be related to Hemimastigophora Hemimastigophora is a group of unicellular, single-celled eukaryotic organisms including the Spironematellidae, first identified in 1988, and the Paramastigidae.
