Helminth parasite larvae collected from Arabian Gulf Fish. 4. description of 4 larvae including two metacercarae, one didymozoid and one acanthocephalan from Emirati coasts

Abstract

Four hilminth larvae from different fish hosts caught from Emirati coasts are described. Two are metacercariae related to genus Stephanostomum, type (I) and (II). Type (I) was found encycsted in body cavities of the Indian halibut Psettodes erumei and the areolate grouper Epinephelus areolatus, and type (II) in the golden stripped goatfish Mulloides flavolineatus. The third larva is related to Acanthocephala and identified as Serrasentis sagittifer. It was collected from the body cavity of the spotted lizard fish Saurida undosquamis. The fourth larva belongs to the didymozoid trematodes, and was found infecting the kidneys of different hosts, such as Saurida undosquamis, the Jack pomfret Parastromateus niger and the mackerel tuna Euthynnus affinis. The larvae related to Stephanostomum type (I) and (II) and the dydimozoid type are described for the first time in the Arabian Gulf.
