“…The other ciliate, originally named Paraglaucoma limacis by Warren(9) is found in the digestive gland ("liver") and intestinal tract of its host, and occasionlally elsewhere among the visceral organs. A ciliate which I believe to be identical with that studied by Warren in South Africa has been found in several localities in Oregon and California ( 6) .? References to some unpublished…”

“…The adoral zone of membranelles (AZM) is represented in C. glaucoma by three definitive membranelles. The three membranelles, MI, M2, M3, are presumably homologous with those known for species of Tetrahymena ( 7,9,22,24,(33)(34)(35)(36). These membranelles resemble those described (36), for members of the related family Philasteridae, as "le champ deltoide" (MI), "le champ trapkzoide" ( M L ) , and "le champ falciforme" ( M:3).…”

SYNOPSIS. An accurate description of Cyclidium glaucoma O.F.M., 1786, is presented. Fixed specimens were treated with the Chatton‐Lwoff silver impregnation technique and the standard Feulgen nucleal reaction. Living material was examined by phase microscopy. Components of the infraciliature have been given special attention, particularly in the buccal area. In brief consideration of the systematic status of this species emphasis is placed upon the close relationship of the pleuronematine and tetrahymenine groups of hymenostome ciliates. Comparisons on structures found in C. glaucoma with corresponding structures in species belonging to quite closely related families are made, and the fundamental nature of the infraciliary tetrahymenal buccal apparatus and the polar basal granule‐complex is discussed.

“…An unknown species of Tetrahymena was found in dead mosquito larvae (Takahashi et al 2004), and I have found Tetrahymena in casts of dragonfly larvae and in remains of dead invertebrates and fish, perhaps attracted by bacteria. From the edaphic environment, Tetrahymena species have been isolated from mosses (Kahl 1926;Kozloff 1946Kozloff , 1957Roque et al 1970) and soil (Brandl et al 2005;Foissner 1987). Were this survey to have included aquatic invertebrates, mosses, and soils more species likely would have been discovered, as predicted (see Introduction).…”

Tetrahymena mitochondrial cox1 barcodes and nuclear SSUrRNA sequences are particularly effective at distinguishing among its many cryptic species. In a project to learn more about Tetrahymena natural history, the majority of >1,000 Tetrahymena-like fresh water isolates were assigned to established Tetrahymena species with the remaining assigned to 37 new species of Tetrahymena, nine new species of Dexiostoma and 12 new species of Glaucoma. Phylogenetically, all but three Tetrahymena species belong to the well-established "australis" or "borealis" clades; the minority forms a divergent "paravorax" clade. Most Tetrahymena species are micronucleate, but others are exclusively amicronucleate. The self-splicing intron of the LSUrRNA precursor is absent in Dexiostoma and Glaucoma and was likely acquired subsequent to the "australis/borealis" split; in some instances, its sequence is diagnostic of species. Tetrahymena americanis, T. elliotti, T. gruchyi n. sp., and T. borealis, together accounted for >50% of isolates, consistent with previous findings for established species. The biogeographic range of species found previously in Austria, China, and Pakistan was extended to the Nearctic; some species show evidence of population structure consistent with endemism. Most species were most frequently collected from ponds or lakes, while others, particularly Dexiostoma species, were collected most often from streams or rivers. The results suggest that perhaps hundreds of species remain to be discovered, particularly if collecting is global and includes hosts of parasitic forms.
