Late disposita. Epibiotica et endobioticaque quae divisione binaria reproducunt. Motilia sunt hyalinaque. Aetates vegetativae epibioticae cellularum endobioticarum plerumque sphaeroes (II–X micrometrorum diametri). Parasiti diatomis actionum cavarum. Cellulae bothrosomia, vacuolia, complexus lipidos, et mitochonria cristis cavis continent. Aliis generis cernenda secundum collectionem molecularem, parasitismum diatomarum actionum cavarum.

Widely distributed. Epibiotic and endobiotic reproduction by binary division. Motile and hyaline. Epibiotic and endobiotic vegetative cells usually spheroidal (2–10 lm in diameter). Parasitizes diatoms with tubular processes. Cells contain bothrosomes, vacuoles, lipid inclusions, and mitochondria with tubular cristae. Distinguished from other genera based on molecular inference, parasitism of diatoms with tubular process.
