All stages of our species had only haplokaryotic nuclei and occurred within a simple membrane-bound vacuole of the host cell cytoplasm. Sporogonial plasmodia divided by budding to give rise to eight or more spores in a parasitophorous vacuole, the envelope of which was subpersistent but occasionally remained intact around groups of spores for short periods of time. The characteristics of this microsporidium are compared to two other species described from P. erichsonii: Thelohania pristiphorae and Pleistophora sp. Evidence is presented to support our contention that these three species are conspecific and that the microsporidium involved should be assigned to the genus Cystosporogenes becoming Cystosporogenes pristiphorae n. comb.}, number={2}, journal={JOURNAL OF INVERTEBRATE PATHOLOGY}, author={DARWISH, A and BROOKS, WM and MOORE, CB}, year={1992}, month={Mar}, pages={178–185} }
