. Flagellar cysts of Blastocrithidia triatomae form from active flagellates by diminution in size. The pellicular microtubules disappear. The inner layer of the cell membrane thickens progressively as the organism shrinks. The fully formed cyst has an electrondense layer that corresponds to the outer layer of the unit membrane. An electron‐lucent layer is approximately twice the thickness of the middle layer of the unit membrane. Inside that is a 92 nm layer that may represent the cytoplasm. The nuclear content is in the form of whorled bundles of 10–15 nm fibrils. The kinetoplast was not seen in electron micrographs of cysts.
