Two new myxozoan species – Myxobolus analfinus sp. n. and Myxobolus debsantus sp. n. are described from Heteropneustes fossilis (Bloch) and Catla-Rohu hybrid carp [Male parent fish Catla catla (Hamilton Buchanan) × Female parent fish Labeo rohita (Hamilton- Buchanan)], respectively. Spores of Myxobolus analfinus are oval with slightly acuminate anterior end and large prominent intercapsular notch. On the other hand, in Myxobolus debsantus spores are spherical to oval with intercapsular notch and posterior sutural markings. In both the myxobolid species polar capsules are unequal. The detailed light microscopic and SEM structures and measurements of these two myxozoans are given.
