During the present investigation, a total of 220 fish specimens belonging to three different species, namely little tunny Euthynnus alletteratus; African snook Lates niloticus; and striped red mullet Mullus surmuletus were collected from January-November 2016 from the coasts of Abu Qir landing site, Alexandria City, south-eastern Mediterranean Sea, Egypt. The collected fish samples were dissected and examined for the presence of helminth parasites. Twenty three out of 220 (10.45%) fish specimens were found to be naturally infected with four species of trematode parasites belonging to three different families of the order Plagiorchiida. The recovered parasite species were collected and identified by applying light microscopic examinations. The present study recorded two new parasite species, namely Stephanostomum alletterani sp. nov. and Bathycreadium mulli sp. nov. belonging to the families Acanthocolpidae and Opecoelidae and infecting E. alletteratus and M. surmuletus, respectively; re-descriptions of the two remaining species namely Acanthostomum spiniceps and Aponurus mulli of the families Acanthostomatidae and Opecoelidae, respectively; to clarifying the measurements of some body parts. Morphological and morphometric characterizations revealed some differences between the present species and other related species detected previously. Future studies are recommended to include advanced molecular characteristics for these species.
