Abstract
Examination of the 35 specimens of White Sea bream, Diplodus sargus Linne 1758 (Sparidae) were caught from the Sirt Coast, Libya and revealed the presence of one new halpigian parasite, Magnibursatus diplodii n. sp. with incidence 25.7% (9 out of 35 fish examined). The main characters of the obtained parasite are; the. Body is small and slender and at the same time, the forebody is shorter than the anterior one. Oral sucker is subterminal, and ventral sucker cup-shaped, strongly muscular, substantially larger than oral one, protuberant. Testes are two in number,, oval in shaped and separated from each other. Seminal vesicle very elongate, coiled. Pars prostatica short, poorly developed. Ovary spherical to oval in shaped, and separated from posterior testis. Vitellarium comprises 2compact, entire, contiguous masses, situated side by side posterior to ovary. The morphological characters and measurements of the present parasite were discussed with the previously related species. Moreover, Sirt coast is considered a new geographical area for halpegian parasites.
