In a parasitological survey of freshwater fishes near Meerut, Uttar Pradesh, India, myxozoan infections in Pabdah catfish Ompok pabda Ham. (Siluriformes: Siluridae) were found. Round plasmodia and scattered spores of Myxobolus ompok n. sp. were found in the kidney of the host. Plasmodia measuring 150–200 μm were located in the renal interstitium. Spores of Myxobolus ompok n. sp. were elongated pyriform, 13.6–14.4 (14.8 ± 0.42) μm long, 5.6–6.4 (6.5 ± 0.33) μm wide, and 5.2–6.4 (5.9 ± 0.43) μm thick with two equal polar capsules measuring 8.0–8.5 (8.2 ± 0.2) μm in length and 1.5–2.4 (1.8 ± 0.33) in width having six filamental turns. Both the morphology and DNA analysis of the 18S rRNA gene revealed that Myxobolus ompok n. sp. is distinct from previously described species of Myxobolus and shares no significant similarity with any other Myxobolus deposited in the GenBank database. Phylogenetic analysis inferred that this species showed the closest similarity to Myxobolus miyarii (KT001495). This is the first record of any Myxobolus sp. from O. pabda in India.
