A new microsporidium was isolated from Chilo suppressalis (Walker) (Lepidoptera: Pyralidae), one of the most important rice pests in China. The morphology and molecular systematics of this novel microsporidium were described in this study. The spores were long oval and measured 3.17 × 1.64 μm on fresh smears. Ultrastructure of the spores was characteristic for the genus Nosema: a diplokaryon, 10-12 polar filament coils of the same type, and posterior vacuole. Small subunit rRNA gene sequence data and phylogenetic analysis further confirmed that the microsporidian species from C. suppressalis belong to the true Nosema sub-group of the genus Nosema. Besides, the microsporidium Nosema sp. CS co..
