Genus Chlamydaster Rainer, 1968
Diagnosis: Cell body surrounded by a fimbriated mucus envelope through which axopods extend, originating from a centrosome; each cell contains two or three contractile vacuoles and an eccentrically located nucleus with a single nucleolus.
The cells have typical centroheliozoan characteristics such as a centrosome with a trilamellate disc, mitochondria with ribbon-like cristae, ball-and-cone kinetocysts, and a peripheral lacunar system. The axopodial axonemes possess a single hexagon of six micro tubules.
