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.

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. Expand
Analysis of the secondary structure of ITS transcripts in peritrich ciliates (Ciliophora, Oligohymenophorea): implications for structural evolution and phylogenetic reconstruction.
This study validated for the first time a secondary structure of ITS1 and ITS2 from peritrich ciliates and demonstrated its potential in helping to resolve deep phylogenetic relationships. Expand
Revision of the family Lagenophryidae Bütschli, 1889 and description of the family Usconophryidae n. fam. (Ciliophora, Peritricha).

Ten species of lagenophryid peritrichs in three genera are redescribed or described for the first time and appear to have evolved separately and convergently from ancestors within Operculigera. Expand
Redescription of Lagenophrys eupagurus Kellicott (Ciliophora, Peritricha, Lagenophryidae) and a Comparison of It with Three Similar Species
Lagenophrys eupagurus, a poorly known loricate peritrich ectocommensal on the hermit crab Pagurus longicarpus, has been rediscovered and is redescribed. Lagenophrys lunatus and L. articularis wereExpand
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. Expand
Further Consideration of the Phylogeny of Some “Traditional” Heterotrichs (Protista, Ciliophora) of Uncertain Affinities, Based on New Sequences of the Small Subunit rRNA Gene
ABSTRACT. The systematic relationships and taxonomic positions of the traditional heterotrich genera Condylostentor, Climacostomum, Fabrea, Folliculina, Peritromus, and Condylostoma, as well as theExpand
Five New Species of Lagenophrys (Ciliophora, Peritricha, Lagenophryidae) from the United States with Observations on Their Developmental Stages
Structural parallels between the telotroch of Lagenophrys and mobiline peritrichs suggest the hypothesis that mobilines evolved from the telosymbionts of a sessiline pentrich which had first evolved into a true larval form. Expand
Vorticella Linnaeus, 1767 (Ciliophora, Oligohymenophora, Peritrichia) is a grade not a clade: redefinition of Vorticella and the families Vorticellidae and Astylozoidae using molecular characters
It is shown that Vorticella microstoma morphotypes, Astylozoon, and Opisthonecta form a well-supported, monophyletic clade, that is distinct from and basal to the family VortICEllidae containing other species of Vorticeslla. Expand
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. Expand
