Genus Dysteria (Huxley, 1857)
Synonyms: Aegyria Ehrenberg, 1838; Ervilia Dujardin, 1841
This genus was first reported by Huxley in 1857.
It is a member of class Phyllopharyngea shows characters such as ciliated stage with somatic kineties mostly as monokinetids that each have a lateral kinetodesmal fibril, a reduced or absent, transverse microtubular ribbon.
This genus belongs to subclass Phyllopharyngia show characters such as trophonts free-swimming, may be sessile but usually not sedentary. Cilia are mainly on ventral surface. Oral ciliature typically composed of one preoral kinety and two circumoral kineties. Macronucleus is heteromerous. Some are symbionts of external body cavities.
This genus belongs to order Dysteriida shows characters such as body is typically laterally compressed. Dorsal surface is rounded. Ventral cilia are not thigmotactic and attached to substrate by unciliated adhesive region or by flexible podite with juxtaposed heteromerous macronucleus. …show more content…
Body may be conspicuously laterally compressed.
The genus Dysteria shows characteristic features like body kinetics are complete.
Body usually ovoid in shape and ventral surface is flattened.
Dorsal surface is dome like and longitudinally ribbed with a cleft on the right lateral
