The present study was conducted to find out the incidence of different helminths in ducks in Assam, India. A total of 108 duck carcasses were collected and internal organs were examined at laboratory. Out of 108 ducks examined, 50 ducks were found positive for different cestode parasites with the incidence rate of 46.29%. Amongst these 50 positive ducks, only in 2 ducks, one new cestode species was recovered which was identified as Apora sp. These parasites were recovered after removal of the cornified layer of gizzard which have not yet recorded from this country from any birds. The percentage of incidence was found to be 4.00% with a total of 45 numbers of parasites recovered. Histopathological study of the affected gizzard revealed multiple longitudinal and cross-sections of the parasites in the sub-keratinized area in cystic cavities.
