Geleiidae
Geleiidae is a family of karyorelict ciliates. It is sometimes synonymized with family Aveliidae. Geleiidae are very large ciliates (200–5000 µm), with a cylindrical shape, and a thinner, often beak-shaped, apical region. They are characterized by a ventral oral region, with buccal infraciliature organized into one intrabuccal kinety and an extrabuccal row. The family name is based on '' Geleia'', the type genus In biological taxonomy, the type genus is the genus which defines a biological family and the root of the family name. Zoological nomenclature According to the International Code of Zoological Nomenclature, "The name-bearing type of a nominal ....

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.

The genus name is a taxonomic patronyms honoring Marcel Avel (1900–1983; professor of anatomy), with slight modification into the '' nomen novum'' ''Avelia'' to avoid a taxonomic homonymy with the moth genus '' Avela''.

Gellertia
''Gellertia'' is a monotypic genus of karyorelict ciliates in the family Geleiidae. It contains a single species, ''Gellertia heterotricha''. The genus is on average 400 µm long and 60 µm in width. It is characterized by a very simplified adoral infraciliature, reduced to a row of two dikinetids (whereas the genus ''Geleia ''Geleia'' is a genus of karyorelict ciliates in the family Geleiidae.

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 ...

Type Genus
In biological taxonomy, the type genus is the genus which defines a biological family and the root of the family name. Zoological nomenclature According to the International Code of Zoological Nomenclature, "The name-bearing type of a nominal family-group taxon is a nominal genus called the 'type genus'; the family-group name is based upon that of the type genus." Any family-group name must have a type genus (and any genus-group name must have a type species, but any species-group name may, but need not, have one or more type specimens). The type genus for a family-group name is also the genus that provided the stem to which was added the ending -idae (for families). :Example: The family name Formicidae has as its type genus the genus ''Formica'' Linnaeus, 1758. Botanical nomenclature In botanical nomenclature, the phrase "type genus" is used, unofficially, as a term of convenience. In the '' ICN'' this phrase has no status. The code uses type specimens for ranks up to fam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
