Karyorelictea
Karyorelictea is a class of ciliates in the subphylum Postciliodesmatophora. Most species are members of the microbenthos community, that is, microscopic organisms found in the marine interstitial habitat, though one genus, ''Loxodes'', is found in freshwater. The majority of karyorelict taxa have not been cultivated in the laboratory, although clonal lines of ''Loxodes'' have been developed. Systematics According to Lynn (2008), the Karyorelictea class is divided into three orders: * Loxodida, containing the families Cryptopharyngidae and Loxodidae; * Protoheterotrichida, containing the families Aveliidae and Geleiidae; * Protostomatida, containing the families Kentrophoridae and Trachelocercidae. These three orders were defined morphologically, and have been confirmed with molecular phylogenetics. An additional family, Wilbertomorphidae, is of uncertain affiliation and has not been assigned to an order. Nuclear dimorphism All ciliates, including karyorelicteans, p ...

Corlissina
''Corlissina'' is a genus of karyorelict ciliates in the family Geleiidae. Only the type species ''Corlissina maricaensis'' is assigned to this genus. ''Corlissina'' is characterized by a paroral ciliature with two rows of polykineties forming a loop at the posterior end. The dikinetids of the adoral zone are organized in short polykineties, followed by a row of monokinetids. The two globular macronuclei are linked by a single micronucleus, a pattern found in most Geleiidae. The genus name is a taxonomic patronym honoring the protistologist John O. Corliss. Comparison and phylogenetic analysis of 18S rRNA sequences showed that ''Corlissina maricaensis'' is the sister group to ''Parduczia orbis''. In turn, these two genera form a clade with ''Geleia ''Geleia'' is a genus of karyorelict ciliates in the family Geleiidae.

Parduczia
''Parduczia'' is a genus of karyorelict ciliates in the family Geleiidae. ''Parduczia'' species are filiform to serpentiform ciliates characterized by their giant size (1200 to 2500 µm on average) and their very long buccal split. The genus name is a taxonomic patronym honoring the protistologist Béla Párducz (1911–1964). Systematics Five species are currently described in the genus ''Parduczia''. * ''Parduczia arcachonense'' (Nouzarède, 1965) Dragesco, 1999 * ''Parduczia filiformis'' (Nouzarède, 1977) Dragesco, 1999 * ''Parduczia martinicense'' (Nouzarède, 1977) Dragesco, 1999 * ''Parduczia murmanica'' (Raikov, 1962) Dragesco, 1999 * ''Parduczia orbis'' (Fauré-Fremiet, 1950) Dragesco, 1999 is the type species of the genus.

Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between organisms ...

Sister Group
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxonomic ...

Phylogenetic Analysis
In biology, phylogenetics (; from Greek φυλή/ φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by Computational phylogenetics, phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, protein amino acid sequences, or morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms. The tips of a phylogenetic tree can be living taxa or fossils, and represent the "end" or the present time in an evolutionary lineage. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the tree. An unrooted tree diagram (a network) makes no assumption about the ancestral line, and does n ...
