During a survey on parasites infecting fishes in Wetlands of Punjab, India, a new myxosporean species, Myxobolus eirasi sp. nov., and one known species Myxobolus venkateshi Seenappa and Manohar, 1981 were found in the Indian major carp Cirrhina mrigala (Ham.). The parasites invade host’s fins and gills. Spores of M. eirasi sp. nov., are pyriform in frontal view; with broader anterior end and narrower bluntly rounded posterior end. Polar capsules are two, equal and oval in shape. Polar filaments are ribbon shaped, forming 3-4 turns. The spores are distinctly different from other species of Myxobolus with similar shape of spores in having two large darkly stained bodies on the lateral margins of the sporoplasm just beneath the polar capsule. Furthermore in the described species a thick band–like structure is present. It goes along the lower margin of the sporoplasm joining the two darkly stained bodies on either side. Intercapsular process is absent.
