Pachyjoenia howa, a new symbiotic parabasalid joeniid flagellate of the termite Postelectrotermes howa
2005
The Joenia-like lophomonad of Postelectrotermes howa is identified by light and electron microscopy as a new genus and species Pachyjoenia howa. Its flagellar area of about 1800 flagella is dome shaped. Basal bodies bear a composite root oriented counterclockwise in addition to the clockwise hook-shaped lamina present in other joeniids. There are four parallel privileged basal bodies. The main parabasal fibre is twisted around the axostyle and splits into several branches bearing Golgi bodies. The axostyle trunk is conspicuous and composed of a bundle of ∼90 small axostyles. There are sausage-shaped bacterial endosymbionts mixed with hydrogenosomes in the cytoplasm and coccoid bacterial end…
Ultrastructure of Joenoides intermedia (Grassé 1952), a symbiotic parabasalid flagellate of Hodotermes mossambicus, and its comparison with other joe…

Light and electron microscopy confirms the validity of the genus Joenoides. The cell is organised like other joeniids with a triangular flagellar area of about two thousand flagella/basal bodies and three privileged basal bodies located apart at the anterior corner of the flagellar area. Characteristically, the two parabasal fibres attached to the basal body #2 are very large and composed of striated subfibres that spread in the cytoplasm, where they sustain Golgi bodies. The flagellar area is surrounded by the axostylar capitulum, which is underlain by a thick layer of preaxostylar fibres, a very strongly amplified component in this species. The axostylar trunk is composed of a bundle of m…
The flagellates of the termite Hodotermopsis sjoestedti with special reference to Hoplonympha, Holomastigotes and Trichomonoides trypanoides n. comb.
2004
Abstract The termite Hodotermopsis sjoestedti harbours a symbiotic fauna of protists comprising at least 11 genera and a much larger number of species. Two oxymonad genera, Pyrsonympha and Dinenympha, are mixed with nine parabasalid genera, two trichomonads, Trichomitopsis termopsidis and Trichomonoides trypanoides n. comb., four spirotrichonymphid genera/species: Spirotrichonympha, Microjoenia, Holomastigotes lanceolata n. sp., Holomastigotes elongatum and three trichonymphid genera/species; Hoplonympha natator, Eucomonympha, Trichonympha. Hoplonympha natator has two anterior symmetrical bundles of ∼60 basal bodies/flagella separated by two parabasal plates. The cell surface is crenelated …
