Description of Polydispyrenia

Life cycle is probably dimorphic or polymorphic and heterosporous, with morphologically different spore types in larvae and adults and possibly in an alternate host; only the polysporous sequence in larvae is known; diplokaryotic and monokaryotic with meiosis at the onset of sporogony; merogony - meronts are diplokaryotic cells, with cisternae of host endoplasmic reticulum associated with the surface but not completely encasing it; sporogony - sporonts are diplokaryotic plasmodia; segmentation of the plasmodium gives rise to many sporoblasts, depending on the number of diplokarya in the plasmodium; spores, 4.5 - 5.5 x 2.5 - 3.5 µm, ovoid and uninucleate; exospore thick, formed as two layers, endospore thick; polaroplast with anterior vesicular and posterior lamellar regions; polar tube with about 6 coils; fat body is greatly hypertrophied and appears white when viewed externally; type species is P. simulii (Lutz and Splendore, 1908) Canning and Hazard, 1982 in adipose tissue of larval blackflies, Simulium spp. (Diptera, Simuliidae).
