Abstract: One morphologically distinct species of genus Aponurus Looss, 1907 were recovered from one family, one genera and one species of marine fish in the waters off the coast of Misurata, western Libya: Aponurus laguncula in Mullus surmuletus. I have used the following characters to distinguish between the species of Aponurus: the general shape of body and vitellaria follicular; length and width body and other organs; size of sinus-sac; length of forebody; post-testicular region; eggs size; and the position of the genital pore, gonads, receptaculum seminis, and acetabulum. Except for the size, the current species of Aponurus showed interspecific similarities in all of the characters enumerated, the most dramatic being in the position of the genital pore in one species (Aponurus laguncula.( During the present study, infection with this digenean was noted in Mullus surmuletus, however with low prevalence of 20% and mean intensity of 4.3±0.43
