Allocreadium aswanensis sp. n. is described from the intestine of freshwater fish Barbus bynni from lake Nasser of Asswan. The new species is compared with other related species of Allocreadium. Different morphological features were studied. Vitellaria extending to the ovary, eggs relatively small, oesophagus long and the two tandem testes are distinctly separated by an intertesticular space are constant features and can be safely used in separation of present species from different Allocreadium parasites. A key for identification of eight species of the genus Allocreadium is given.
