Abstract The parabasalids include parasites (e.g. trichomonads) as well as many hypermastigid flagellates which live in termites and other wood-eating insects and contribute to the cellulose-digesting capacity of those animals. A hypermastigid, Joenina pulchella Grassi, is shown to have a “flagellar area” composed of 1300 flagella, including three privileged basal bodies which have homologues in the trichomonads. The cytoskeleton includes preaxostylar fibres, two parabasal fibres and two…

Ultrastructure of Joenoides intermedia (Grassé 1952), a symbiotic parabasalid flagellate of Hodotermes mossambicus, and its comparison with other joeniid genera
Light and electron microscopy confirms the validity of the genus Joenoides and the loss of the flagellar area and the origin of spindle microtubules from the atractophores which are attached by a peduncle at the base of the parabasal fibres.
Molecular Evidence for the Polyphyly of Macrotrichomonas (Parabasalia: Cristamonadea) and a Proposal for Macrotrichomonoides n. gen.
It is hypothesised that the macrotrichomonad body plan represents the ancestral state of cristamonads, from which other major forms evolved, and proposed transferring M. restis to a new genus, Macro Trichomonoides.
The Amoeboid Parabasalid Flagellate Gigantomonas herculea of the African Termite Hodotermes mossambicus Reinvestigated Using Immunological and Ultrastructural Techniques
The amoeboid form of Gigantomonas herculea, a symbiotic flagellate of the grass-eating subterranean termite Hodotermes mossambicus from East Africa, is observed by light, immunofluorescence and transmission electron microscopy.
The symbiotic fauna of the African termite Hodotermes mossambicus identification of four flagellate species of the genera Spironympha, Trichomonoides and Retortamonas
Two Spironympha species were described by light immunofluorescence and electron microscopy and the species identification differs from that of described in Dogiel (Russkii Arkhiv Protistologii 1:172–234, 1922).
Characterization of new cristamonad species from kalotermitid termites including a novel genus, Runanympha
Seven new species of cristamonad symbionts from Comatermes, Calcaritermes, and Rugitermes termites from Peru and Ecuador are described, three of which represent new species within described genera.


Ultrastructure of Ditrichomonas honigbergii N. G., N. Sp. (Parabasalia) and Its Relationship to Amitochondrial Protists
Ditrichornonas honigbergii is capable of ingesting and digesting bacteria by phagocytosis and the structure is similar to that of retortamonads and the relationship of trichomonads to other amitochondrial protists is discussed.
The Fine Structure of the Centriolar Apparatus and Associated Structures in the Flagellates Deltotrichonympha and Koruga. II. Division
An electronmicroscopic study was made of the centriolar apparatus in the rostrum of Deltotrichonympha operculata and Koruga bonita, 2 closely related hypermastigote flagellates from the Australian termite, Mastotermes darwiniensis, which revealed a pair of typical centrioles in an interphase metazoan cell.
Budding and Asymmetric Reproduction of a Trichomonad with as Many as 1000 Nuclei in Karyomastigonts: Metacoronympha from Incisitermes
Metacoronympha senta Kirby's report of polygonal compartments, formed by contiguous nuclear membranes, prove by electron microscopy to be microtubules of the axostyles arrayed as a polygon around each nucleus.
Ultrastructure of the Trichomonad Flagellate Stephanonympha nelumbium
The fine structure of S. nelumbium corresponds with that of other calonymphids, but the main difference to Calonympha is that the axostyle does not embrace the nucleus but passes it in form of a flattened rod.
Phylogenetic Identification of Hypermastigotes, Pseudotrichonympha, Spirotrichonympha, Holomastigotoides, and Parabasalian Symbionts in the Hindgut of Termites
The phylogenetic diversity of parabasalian flagellates was examined based on the sequences of small subunit ribosomal RNA genes amplified directly from the mixed population of flageLLates in the hindgut of lower termites, suggesting that the Pseudotrichonympha group is the most probable ancient lineage ofParabasalids and the Trichonympha Group is the secondly deep-branching lineage.
