Wobblata is a paraphyletic grouping of all placidozoans except Opalinata. It unites the classes Placididea, Nanomonadea and Opalomonadea. [1]
Members of this group are ancestrally aerobic phagotrophic biciliates. [1] They have tubular mitochondrial cristae and a hairy anterior cilium. [1] They have a split right microtubular root, [1] i.e. one of the two (left and right) microtubular roots that support the feeding groove is split in two. [2] They lack a cytopharynx, and some of them have lost their anterior cilium. [1]
The cladogram shows the relationships between Wobblata and the rest of Opalozoans. [1]

Pedinellales is a group of single-celled algae found in both marine environments and freshwater.
The Apusozoa are an Obazoa phylum comprising several genera 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.
An undulipodium or undulopodium, or a 9+2 organelle is a motile filamentous extracellular projection of eukaryotic cells. It is basically synonymous to flagella and cilia which are differing terms for similar molecular structures used on different types of cells, and usually correspond to different waveforms.
Bicosoecida (ICZN) or Bicosoecales/Bicoecea (ICBN) is an order of Bikosea, a small group of unicellular flagellates, included among the heterokonts. Informally known as bicosoecids, they are a small group of unicellular flagellates. The cells are free-living, with no chloroplasts, and in some genera are encased in a lorica.
Sagenista is a group of heterokonts containing the labyrinthulids and Eogyrea, a class of yet uncultured protists. Originally, it contained the Labyrinthulids and bicosoecids. The bicosoecids have been removed, and Eogyrea were added, in order to make the group monophyletic.
Opalinata is a superclass of non-phagotrophic heterokonts that unites the classes Opalinea and Blastocystea, and is the sister group to Opalomonadea.
Carpediemonas is genus of Metamonada, and belongs to the group Excavata. This organism is a unicellular flagellated eukaryote that was first discovered in substrate samples from the Great Barrier Reef. Carpediemonas can be found in anaerobic intertidal sediment, where it feeds on bacteria. A feature of this species is the presence of a feeding groove, a characteristic of the excavates. Like most other metamonads, Carpediemonas does not rely on an aerobic mitochondrion to produce energy. Instead, it contains hydrogenosomes that are used to produce ATP. This organism has two flagella: a posterior one used for feeding on the substrate, and an anterior one that moves in a slower sweeping motion. Carpediemonas is assigned to the fornicates, where similar Carpediemonas-like organisms are used in researching the evolution within excavates. Although Carpediemonas is a member of the metamonads, it is unusual in the sense that it is free-living and has three basal bodies.
Phaeothamniophycidae is a subclass of heterokont algae. It contains two orders, Phaeothamniales and Pleurochloridellales, and consists of species separated from Chrysophyceae.
Bigyra is a possibly paraphyletic phylum of heterotrophic organisms belonging to the Stramenopile lineage. It includes the groups Bicosoecida, Opalinata and Labyrinthulea, as well as several small clades that were initially discovered through environmental DNA samples: Nanomonadea, Placididea, Opalomonadea and Eogyrea.
Opalozoa is a subphylum of heterotrophic protists of the phylum Bigyra, and is the sister group to Sagenista. Opalozoans are non-photosynthetic heterokonts that are ancestrally phagotrophic but many times have evolved to be osmotrophic saprotrophs in the gut of vertebrate animals.
Psalteriomonas is a genus of excavates in the group of Heterolobosea. The genus was first discovered and named in 1990. It contains amoeboflagellate cells that live in freshwater anaerobic sediments all over the world. The microtubule-organizing ribbon and the associated microfibrillar bundles of the mastigote system is the predominant feature in Psalteriomonas. This harp-shaped complex gives rise to the name of this genus. Psalteriomonasforms an endosymbiotic relationship with methanogenic bacteria, especially with Methanobacterium formicicum There are currently three species in this genus: P. lanterna, P. vulgaris, and P. magna.
Perkinsea is a class of alveolates.
Tsukubamonas is a monotypic genus of excavates that contains a single species, Tsukubamonas globosaYabuki et al. 2011. T. globosa is a free-living flagellate that was isolated from a pond in the University of Tsukuba, Japan.
Placidozoa is a recently defined non-photosynthetic lineage of Stramenopiles.
Bicosidia is a subclass of Bikosea, a small group of unicellular flagellates, included among the heterokonts.
Rictus is a genus of Bikosea, a small group of unicellular flagellates, included among the heterokonts.
Nanum is a genus of bicosoecids, a small group of unicellular flagellates, included among the heterokonts.
Solenicola setigera is a species of marine stramenopile, and the only species classified within the genus Solenicola.
Opalomonadea is a class of biciliate phagotrophic opalozoans with an anterior hairy cilium, often from anaerobic habitats. It is a monophyletic group previously known as clade MAST-12, sister to Opalinata. This group was discovered through marine environmental DNA samples; no species have yet been described or cultured.
Nanomonadea is a class of biciliate phagotrophic, non-photosynthetic free-living opalozoans, coontaining the sole order Uniciliatida. This monophyletic group previously known as clade MAST-3 is characterized by a single hairless posterior cilium and absence of an anterior cilium.
