Abstract
Nematodes of the genus Hysterothylacium (Nematoda: Raphidascarididae) infect marine fishes either with larval and adult stages. Humans can be accidentally infected upon consumption of infected seafood. Inspire of their importance, little is known about their occurrence and systematics in Egypt. During the present study, different Red Sea fishes at Hurghada (Egypt) were examined for parasitic infection. Among others four types of third-stage larvae and two types of fourth-stage larvae of Hysterothylacium sp. were for the first time redescribed from Egypt and compared from each other as well as from otherwise elsewhere previously described forms. Moreover, their comparative morphometry, fish hosts differences as well as their medical importance, had been discussed.
