ABSTRACT

Four species of Microsporidia parasitizing Branchiopod hosts are described based on the light and ultrastructural data. Microsporidium sp. from the body cavity of Lepidurus apus, produced ovoid spores 3.5±0.4ґ2.2±0.3 mm in size. Mononuclear (asymmetrical spores of Larssonia hiberna sp. n., measured 3.8±0.1x2.0±0.2 mm, were found in fat tissues and hemocoel of Daphnia magna. Filamentous episporal surfacing inverted polaroplast and 8-9 coiled isofilar polar filament are characteristic features of this species. Berwaldia singularis Larsson and Microsporidium stagnalis sp. n. from D. pulex are presented. Ellipsoidal spores of M. stagnalis, 4.8±0.4ґ2.4±0.3 mm in sizes, formed a two-layered exospore, tripartite lamellar and tubular polaroplast, and the isofilar polar filament coiled in a two-layer spiral of 14 rings.
