new host and locality records the two trematodes gymnotergestia chaetodipteri and opechona sardinellae described by nahhas and cable in 1964 with review of the two genera

The two trematode genera Gymnotergestia [Nahhas and Cable, 1964] and Opechona looss [1907] were reviewed and discussed. Gymnotergestia chaetodipteri [Nahhas and Cable, 1964] and Opechona sardinellae [Nahhas and Cable, 1964] were redescribed from Serranus scriba and Labrus bergylata, respectively, from Libya. This represents a new host record and new locality. A comparison between the original description and the present work was presented
