Abstract
A description is given of Macro Gyrodactylus clasrii Gussev 1961, a monogenean from the gills of Clarias lazera inhabiting Nile Delta waters in Egypt. This is the first record of a monogenean of the genus Macrogyrodactylus in Egypt. The gills of C. lazera represents a new microhabitat for M. clarii. Particular attention has been paid to the anatomy of the anterior adhesive apparatus, digestive system, reproductive system and haptoral selerites. A vagina was found to be absent. The possible functions of some internal organs are discussed.
