Pathogenic scuticociliates, which are common in the haemolymph or tissues of maricultured animals and often cause serious diseases, are a species-rich assemblage with mostly unresolved systematic relationships, especially in some less-studied groups. In the present study, we sequenced the small-subunit rRNA gene of six species of scuticociliates, Uronemella parafilificum, Metanophrys sinensis, Parauronema longum, Cohnilembus verminus, Porpostoma notata and Ancistrum crassum, the last two of… 
Insights into the phylogenetic and taxonomy of philasterid ciliates (Protozoa, Ciliophora, Scuticociliatia) based on analyses of multiple molecular markers.
TLDR
48 new sequences for three linked genes are characterized and phylogenetic trees are constructed to assess the inter- and intra-generic relationships of philasterids, revealing that the combined three-gene tree provides more resolution in nodes than in the SSU-rDNA topologies.

TLDR
An improved diagnosis of the genus Uronemita is supplied, which has been absent since the establishment of this genus, and a key to the new species is provided.
Redescription and phylogenetic analyses of Durchoniella spp. (Ciliophora, Astomatida) associated with the polychaete Cirriformia tentaculata (Montagu, 1808).
TLDR
Endocommensal astome ciliates retrieved from the middle intestine of a marine cirratulid polychaete, Cirriformia tentaculata, collected in the bay of Roscoff and on the Southwest English coast revealed the presence of endocytoplasmic cocci and rod-shaped bacteria surrounded by a very thin membrane.
Phylogeny and systematic revision of the karyorelictid genus Remanella (Ciliophora, Karyorelictea) with descriptions of two new species.
TLDR
An illustrated taxonomic key based on morphologic and morphometric characteristics and containing all Remanella species considered identifiable in this revision is presented, based on a critical review of the literature.
Phylogenetic analyses of cyclidiids (Protista, Ciliophora, Scuticociliatia) based on multiple genes suggest their close relationship with thigmotrichids.
TLDR
Phylogenetic analyses reveal that traditional cyclidiids are associated with thigmotrichs rather than pleuronematids as expected, and the validity of the newly-reported genus Falcicyclidium is confirmed by the molecular data.
Taxonomic Clarification of A Well-Known Pathogenic Scuticociliate, Miamiensis avidus Thompson & Moewus, 1964 (Ciliophora, Scuticociliatia)
TLDR
A population of M. avidus was collected from the skin of pharaoh cuttlefish cultured near the East China Sea, Ningbo, China and its morphology and phylogeny were investigated in detail based on living characters, infraciliature, small subunit rDNA and ITS1-5.8S-ITS2 region sequences.
Multigene-based analyses on evolutionary phylogeny of two controversial ciliate orders: Pleuronematida and Loxocephalida (Protista, Ciliophora, Oligohymenophorea).
TLDR
Describing secondary structures of ITS2 transcripts and the variable region 4 (V4) of the small subunit ribosomal RNA (SSU-rRNA) are predicted, revealing that ITS2 structures are conserved at the order level while V4 region structures are more variable than ITS 2 structures.
Taxonomy and morphology of four "ophrys-related" scuticociliates (Protista, Ciliophora, Scuticociliata), with the description of a new genus, Paramesanophrys gen. nov.
TLDR
The redescription of the three previously known species can be summarized as follows: improved diagnosis is provided for Metanophrys sinensis Song & Wilbert, 2000 based on the original description and the present study, and some population-dependent characteristics of the new Mesanphrys carcini isolate are presented.
Taxonomy and molecular phylogeny of three freshwater scuticociliates, with descriptions of one new genus and two new species (Protista, Ciliophora, Oligohymenophorea).
Three freshwater scuticociliates, Apouronema harbinensis gen. nov. spec. nov., Cyclidium vorax spec. nov., and C. glaucomaMüller, 1773, collected from rivers in Hulan District, Harbin, northeastern
Morphology and SSU rRNA gene sequences of three Frontonia species, including a description of F. subtropica spec. nov. (Ciliophora, Peniculida).
TLDR
Comparisons with sequences of morphologically similar congeners clearly support the validity each species and improve diagnoses for F. canadensis and F. magna based on current and previous reports.

Phylogenetic consideration of two scuticociliate genera, Philasterides and Boveria (Protozoa, Ciliophora) based on 18 S rRNA gene sequences.
TLDR
Two scuticociliates genera, represented by two rare parasitic species, Philasterides armatalis (order Philasterida) and Boveria subcylindrica (order Thigmotrichida), were studied, and phylogenetic trees concerning these two genera were constructed based on their 18 S rRNA gene sequences.
Molecular phylogeny of the scuticociliate, Philaster (Protozoa, Ciliophora), with a description of a new species, P. apodigitiformis sp. nov.
TLDR
Results indicate that Philaster apodigitiformis clearly falls into the order Philasterida and it is most closely related to the Uronema‐Paranophrys assemblage, which groups with clusters consisting of families Uronemat Families, Parauronematidae, Thyrophilacidae and Entorhipidiidae.
Phylogeny of six oligohymenophoreans (Protozoa, Ciliophora) inferred from small subunit rRNA gene sequences
TLDR
The predicted secondary structures of the variable region 4 of the SSrRNA gene sequences show that the size of the terminal bulge in Helix E23–7 is probably different for the orders Philasterida and Pleuronematida.
Phylogenetic positions of two marine ciliates, Metanophrys similis and Pseudocohnilembus hargisi (Protozoa, Ciliophora,Scuticociliatia), inferred from complete small subunit rRNA gene sequences
TLDR
The results show that this gene comprises 1763 and 1753 nucleotides in the two marine ciliates respectively, which are phylogenetically closely related to the clade containing Mesanophrys carcini and Anophyroides haemophila, which branches basally to other species within the order Philasterida.
The systematic position of Paraspathidium Noland, 1937 (Ciliophora, Litostomatea?) inferred from primary SSU rRNA gene sequences and predicted secondary rRNA structure.
TLDR
Results support the placement of Paraspathidium close to prostomateans and plagiopyleans, or even as a distinct group possibly at ordinal rank, within the class Plagiopylea.

TLDR
Gene sequence data confirm the phylogenetic distinctness of spirotrichean, armophorean, plagiopylean, and oligohymenophorean endosymbionts and explain why the Thyrophylacidae and Entorhipidiidae are paraphyletic based on the SSrRNA gene sequences.

The ITS2 (ITS--internal transcribed spacer) region of the rDNA in 11 representative scuticociliates and two ambiguously related genera was analyzed and found that the secondary structure information could help to improve alignment and utilize appropriately phylogenetic strategies.
