During the present investigation, a total of 569 fish specimens belonging to Boops boops, were collected from 2020 from the coasts water Alexandria City, Mediterranean Sea, Egypt. The collected fishs were dissected and examined for the presence of helminthes parasites. A total of 232/ 569 (40.83%) were found naturally infected with trematode parasites. The rate of infection was 16 (6.03%) fish. The recovered parasite species were collected and identified by applying light microscopic examinations. So, this study was the re-description of Sclerodistomum aegyptiaca in new host (Boops boops) from Alexandria coastal area. Morphological and diagnostic morphometric characterizations showed some differences between the present species and other related species detected previously.
