A tintinnid ciliate isolated from waters of the Thames River (Connecticut, USA) is described through combined in vivo observation, protargol impregnation, and phylogenetic analysis. The novel genus Dartintinnus and its type species, D. alderae are distinct from established tintinnid taxa by a lorica that collapses on both anterior and posterior ends. Dartintinnus is placed in the family Eutintinnidae based on a hyaline, elongated lorica opened at both ends, a ciliary pattern including a ventral… 

Taxonomy and Phylogeny of Two Tintinnid Ciliates of Leprotintinnus (Protista, Ciliophora, Choreotrichida) Combining the Loricae, Cytological, Ontogenetic Features, and Barcoding Genes

The molecular phylogeny confirmed that Leprotintinnus species are closely related to some species of Tintinnopsis, Stylicauda, Rhizodomus, and Climacocylis and the lorica of L. nordqvisti is polymorphic or plastic.

Three redescriptions in Tintinnopsis (Protista: Ciliophora: Tintinnina) from coastal waters of China, with cytology and phylogenetic analyses based on ribosomal RNA genes

It is inferred that the ciliary tuft and details such as the commencement of the rightmost kinety in the lateral ciliary field are synapomorphies that may help clarify the systematics of Tintinnopsis -like taxa.

Redescription of five tintinnine ciliates (Alveolata: Ciliophora: Oligotrichea) from coastal waters of Qingdao, China

The morphology in vivo of the lorica and cell proper of all five species are described and compared with original and subsequent descriptions and three are newly recorded from China.

Morphology and Molecular Phylogeny of Two Freshwater Oligotrich Ciliates (Protozoa, Ciliophora, Oligotrichia), Pelagostrombidium fallax (Zacharias, 1895) Krainer, 1991 and Limnostrombidium viride (Stein, 1867) Krainer, 1995, with Brief Notes on Stomatogenesis

Phylogenetic analyses, based on SSU rRNA gene sequence data, reveal that P. fallax and L. viride cluster with Strombidium species while the result of an AU test did not reject the possibility of monophyly of the family Pelagostrombidiidae.

Integrative taxonomy and molecular phylogeny of three poorly known tintinnine ciliates, with the establishment of a new genus (Protista; Ciliophora; Oligotrichea)

The phylogenetic analyses support the assertion that cytological characters are taxonomically informative for tintinnines and contribute to the broadening of the understanding of the tintinnine biodiversity and evolution.

Symbioses of Ciliates (Ciliophora) and Diatoms (Bacillariophyceae): Taxonomy and Host–Symbiont Interactions

: The nature of the plankton symbioses between ciliates and diatoms has been investigated from the tropical South Atlantic Ocean, and Mediterranean and Caribbean Seas. The obligate symbioses of the

Symbioses of Ciliates (Ciliophora) and Diatoms (Bacillariophyceae): Taxonomy and Host–Symbiont Interactions

Symbioses allow sessile peritric ciliates to extend their distribution in the pelagic environment, permit boreal-polar related diatoms such as C. coarctatus or Fragilariopsis doliolus to inhabit tropical seas, and help large diatOMs to extended their survival under unfavorable conditions.

Global and local DNA (meta)barcoding reveal new biogeography patterns in tintinnid ciliates

Local alpha and beta diversity analyses show that assemblage differences among estuarine, coastal and open waters are not significant regarding richness, but are significant in terms of phylogenetic composition, and confirm spatial restric­ tion of boreal and austral taxa, and stress that cosmopolitanism cannot be assessed by molecular methods that lump data from potentially endemic and commonly widespread taxa.

Reconciling Cladistic and Genetic Analyses in Choreotrichid Ciliates (Ciliophora, Spirotricha, Oligotrichea)

The two clusters of Favella species in small subunit rRNA gene trees are supported by morphological features, justifying a separation at genus and family level, including an updated hypothesis about the evolution of the somatic ciliary patterns.

The proteolytic resistance of some loricae does not reject the idea of a proteinaceous nature, as proteins in S-layers of some archaea and in most naturally occurring prions show comparable reactions.

What Morphology and Molecules Tell Us about the Evolution of Oligotrichea (Alveolata, Ciliophora)

The evolution of the dominant marine plankton ciliates, the oligotrichids and choreotrichidids, is analysed for morphologic and genetic convergences and apomorphies based on literature and data and has taxonomic implications.

Three rDNA Loci‐Based Phylogenies of Tintinnid Ciliates (Ciliophora, Spirotrichea, Choreotrichida)

Findings highlight the difficulties in using variable locus‐based cut‐off divergences in circumscribing tintinnid morphospecies and show that Leprotintinnus was closely related to Tintinnopsis radix and branched distinctly apart from the family Tintinnieidae.
