A Molecular Phylogenetic Investigation of Zoothamnium (Ciliophora, Peritrichia, Sessilida) 1
It is apparent that Zoothamnium is a richly diverse genus and that a much more intensive investigation will be necessary to resolve its phylogeny, indicating that characteristics of stalk and peristomial structure traditionally used to differentiate taxa at the generic level and above may not be uniformly reliable.
Analysis of the secondary structure of ITS transcripts in peritrich ciliates (Ciliophora, Oligohymenophorea): implications for structural evolution and phylogenetic reconstruction.
Phylogeny and systematic revision of the family Pseudokeronopsidae (Protista, Ciliophora, Hypotricha), with description of a new estuarine species of Pseudokeronopsis
A new estuarine species of Pseudokeronopsis is described, which is believed to be the first of its kind to be described in the world.
Phylogeny of Six Genera of the Subclass Haptoria (Ciliophora, Litostomatea) Inferred from Sequences of the Gene Coding for Small Subunit Ribosomal RNA
Both the subclass Haptoria and the order Haptorida were partially unresolved, possibly paraphyletic assemblages of taxa in all analyses, creating doubts about the traditional placement of some haptorid taxa.

ABSTRACT. The systematic relationships and taxonomic positions of the traditional heterotrich genera Condylostentor, Climacostomum, Fabrea, Folliculina, Peritromus, and Condylostoma, as well as the…
Phylogenetic investigation on five genera of tintinnid ciliates (Ciliophora, Choreotrichia), based on the small subunit ribosomal RNA gene sequences
An integrative approach to phylogeny reveals patterns of environmental distribution and novel evolutionary relationships in a major group of ciliates
Reconstruction of ancestral states revealed that peritrichs may have transitioned repeatedly from freshwater to brackish/marine/hypersaline environments and provided a model of how to elucidate evolution in the context of ecological niches in any lineage of microbial eukaryotes.
Vorticella Linnaeus, 1767 (Ciliophora, Oligohymenophora, Peritrichia) is a grade not a clade: redefinition of Vorticella and the families Vorticellidae and Astylozoidae using molecular characters…
A Molecular Phylogenetic Investigation of Opisthonecta and Related Genera (Ciliophora, Peritrichia, Sessilida)
On the basis of genetic evidence, genera of the families Opisthonectidae and Astylozoidae are assigned to the family Vorticellidae, and Epistylis galea, Campanella umbellaria, and Opercularia microdiscum are confirmed as comprising an extremely distinct, monophyletic, but morphologically heterogeneous clade that is basal to other clades of sessiline peritrichs.
Phylogenetic and Taxonomic Revision of an Enigmatic Group of Haptorian Ciliates, with Establishment of the Kentrophyllidae fam. n. (Protozoa, Ciliophora, Litostomatea, Pleurostomatida)
It is hypothesize that the two-sutures of Kentrophyllum is a plesiomorphy within the Pleurostomatida and the unique peripheral kinety might represent an autapomorphy of Kentrhyllum.
