Belongs within: Spirotricha.Contains: Holosticha, Oxytricha. The Stichotrichida are a group of ciliates in which cirri are often arranged in longitudinal files (Adl et al. 2019). In Spirofilidae, the files are curved or spiralled around the body (Lynn & Small 2002). Characters (Adl et al. 2019): Ventral cirri as one or more longitudinal and linear files or as frontoventral cirri, typically conspicuous, arranged… Continue reading Stichotrichida

Belongs within: Ciliophora. The Karyorelictea are a group of ciliates containing two or more non-dividing macronuclei (Adl et al. 2019). Characters (Adl et al. 2019): Two to many macronuclei containing approximately but sometimes slightly more than the diploid amount of DNA; macronuclei not dividing but replaced by division of micronuclei; major postciliary ribbons separated by two groups of microtubules. <==Karyorelictea [Karyorelictina]… Continue reading Karyorelictea

Belongs within: Ciliophora.Contains: Apostomatia, Astomatia, Peniculia, Scuticociliatia, Tetrahymenida, Mobilida, Vorticellidae, Epistylididae, Operculariidae, Vaginicolidae. The Oligohymenophorea are a group of ciliates often possessing a distinct oral apparatus in a ventral oral cavity or infundibulum (Adl et al. 2019). Characters (Adl et al. 2019): Oral apparatus often with distinct right paroral kinety and typically three left oral polykinetids, residing in ventral oral cavity or… Continue reading Oligohymenophorea

Belongs within: Ciliophora.Contains: Cyrtophoria, Suctoria. The Phyllopharyngea are a group of ciliates with a radial array of microtubular ribbons around the oral region. Members of the subgroup Synhymeniida have ribbon-like subkinetal nematodesmata arising from somatic monokinetids and extending beneath the kineties as nematodesmata (Adl et al. 2019). Characters (Adl et al. 2019): Ciliated stage with somatic kineties… Continue reading Phyllopharyngea

Belongs within: Ciliophora. The Heterotrichea are a group of ciliates with the polygenomic macronucleus dividing by extra-macronuclear microtubules, and major postciliary ribbons separated by one microtubule (Adl et al. 2019). <==Heterotrichea [Heterotricha, Heterotrichida, Heterotrichina] |–ClimacostomidaeLS02 | |–Climacostomum Stein 1859L03, LS02 | | `–C. virensL03 | `–Copemetopus Villeneuve-Brachon 1940LS02 | `–C. chesapeakensisLS02 `–+–Stentor Oken 1815L03, LS02 [Stentoridae] | |–S.… Continue reading Heterotrichea

Belongs within: Oligohymenophorea. The Vorticellidae are a group of sessile ciliates that live attached to their substrate by a stalk containing a contractile myoneme. Zooids may be solitary, gregarious or colonial, and are usually aloricate (Lynn & Small 2002). <==Vorticellidae [Ophrydiidae] |–Cothurniopsis imberbisD01 |–EpicarchesiumAB19 |–PelagovorticellaAB19 |–PseudovorticellaAB19 |–Ruthiella Schödel 1983LS02 | `–R. gammariLS02 |–Intranstylum Fauré-Fremiet 1904LS02… Continue reading Vorticellidae
