Merogony occurs principally in leucocytes and thrombocytes and to a lesser extent in the erythrocytes. No pigment is produced.
Gametogony, like merogony, occurs principally in leucocytes and thrombocytes and to a lesser extent in the erythrocytes. Again no pigment is produced.
Nothing is currently known about parasitic forms outside the blood.
The only known host is the spectacled caiman (Caiman crocodilus crocodilus).
This genus has been described in South America.
