AbstractThe genus Diaphoropodon, Archer 1869, comprises filose amoebae with agglutinated tests made of quartz grains, diatom frustules and other particulate materials. The key trait of the genus is a hyaline theca covered with numerous 5‐ to 10‐μm‐long, hairlike rods.

Thecofilosea is a class in Cercozoa (Rhizaria) comprising mainly freshwater-inhabiting algivores. Recently, numerous isolates of thecofilosean amoebae have been cultured and were characterized by an integrated morphological and molecular approach. The captivating spine-bearing taxa in Thecofilosea were not yet molecularly characterized due to being ...

Distribution and Diversity of a Protist PredatorCryothecomonas(Cercozoa) in Arctic Marine Waters
Journal of Eukaryotic Microbiology, 2012ABSTRACTHeterotrophic nanoflagellates (HNFs) are key components in microbial food webs, potentially influencing community composition via top‐down control of their favored prey or host. Marine cercozoanCryothecomonasspecies are parasitoid and predatory HNFs that have been reported from ice, sediments, and the water column.

Novel Lineages in Cercozoa and Their Feeding Strategies [PDF]
, 2016 The term protist describes an informal grouping of unicellular eukaryotic organisms that do not form tissues. With a tremendous diversity in morphology and ecology, they represent the vast majority of eukaryotic heterogeneity of which only a small fraction is yet known.

Naked filose and reticulose protozoa were long lumped as proteomyxids or left outside higher groups. We cultivated eight naked filose or reticulose strains, did light microscopy, 18S rDNA sequencing and phylogeny (showing all are Cercozoa), and sequenced 80 environmental 18S-types.

Cercomonads are among the most abundant and widespread zooflagellates in soil and freshwater. We cultured 22 strains and report their complete 18S rRNA sequences and light microscopic morphology. Phylogenetic analysis of 51 Cercomonas rRNA genes shows in each previously identified major clade (A, B) two very robust, highly divergent, multi-species ...

A culture of Thaumatomastix was isolated from a sediment sample collected in Oslofjorden and established as a monospecific strain (UIO286). Based on this culture, light and transmission electron microscopy and phylogenetic analyses were carried out. Thaumatomastix species are confined within the order Thaumatomonadida of the class Imbricatea and phylum

Gymnophrys cometa and Lecythium sp. are core Cercozoa : evolutionary implications
2003Recent phylogenetic analyses based on different molecular markers have revealed the existence of the Cercozoa, a group of protists including such morphologically diverse taxa as the cercomonad flagellates, the euglyphid testate filose amoebae, the chloroplast-bearing chlorarachniophytes, and the plasmodiophorid plant pathogens.

Házas amőbák (Amoebozoa: Arcellinida és Cercozoa: Filosea) Gyűrűfű térségében
Natura Somogyiensis, 2009The purpose of this study was to extend our knowledge of the testate amoebae in Hungary. Soil and to a lesser extent sediment samples were investigated in the frame of the 2. Biodiversity Day in Hungary, organized in a 1 km2 area around the abandoned south-transdanubian village Gyűrűfű in the Zselic Hills.
