Classification:
Kephyrion Pascher 1911; 32 of 62 species descriptions are currently accepted taxonomically (Guiry and Guiry 20123). Order Chromulinales; Family Dinobryaceae Synonym: Stenocalyx Schiller.
Morphology:
Flagellated unicells with a ‘bottle’ or ‘jar’ shaped lorica, often with spiral ridges. Asexual reproduction is similar to Dinobryon in that one daughter cell leaves lorica (apparently as a temporary amoeba) and builds its own new lorica.
Similar genera:
Pseudokephyrion has two emergent flagella. Often the second emergent flagellum is difficult to see, so some species of Kephyrion may be transferred to Pseudokephyrion (Guiry and Guiry).
Habitat:
Freshwater lakes. Generally rare but widespread.
