A new species of microsporidian (sporozoan) parasite from the ovaries of the golden shiner (Notemigonus crysoleucas) from southern Illinois is described. The name Plistophora ovariae n. sp. is suggested. Fresh spores are ovoid or ellipsoid and measure 8.42±0.17 by 4.24±0.15 microns for spore length and width, respectively. The primary site of infection is in the ovary, but the parasite is occasionally found in the liver and kidney of female fish. The parasite is not found in either the testis, kidney, or liver of male fish. The importance of this parasite to the bait industry is suggested, as it reduces fecundity and is suspected of causing sterility in older female brood fish. The parasite is of wide distribution, occurring in commercial bait hatcheries in Missouri, Arkansas, and Kentucky, as well as in Illinois.
