Background: Genus Acanthocolpus (Trematoda: Acanthocolpiidae) is one of the most important zoonotic digenean with wide geographic distribution in the world. The purpose of the present study was to describe morphological and morphometrical characteristics of Acanthocolpus species, currently prevalent in marine fish fauna of Puri coast, Orissa, India.Methods: Gastro-intestinal organs of Leiognathus daura (Cuvier) in Puri coast, Orissa, India, were examined for infectivity with digenean trematode species. For examination and measurements of hel­minthes, acetoalum carmine staining was performed, followed by cam­era Lucida drawings of morphological characters and measure­ments of morphometrical criteria with a calibrated microscope. Us­ing valid trematode systematic keys, almost all the parasites were identi­fied at the level of species.Results: Overall, 36 marine fishes were found infected with at least one species of Acanthocolpus. Considering morphological characteris­tics of Acanthocolpus, two species were identified as new species includ­ing Acanthocolpus durghai sp.nov. and Acanthocolpus amrawatai sp.nov.Conclusion: During the survey of helminth parasites, collected six different species of the genus Acanthocolpus, out of these two are new species, another is redescribed to show certain variation, the new para­site was obtain from the intestine of marine fish Leiognathus daura (Cuvier)
