Abstract : A total of twenty species of parasites were studied using light and scanning electron microscopy from 503 specimens of five species of fishes of the family Lethrinidae from the Red Sea ,Jeddah, Saudi Arabia . 460 (91.45%) of fishes were found infected with ectoparasites and 287 (57.06%) with endoparasites. Thirteen species of parasites are proposed as new species in the present study. The new species of parasites include three copepods, one isopod, four digenetic trematodes, one cestode larvae and five nematodes. Five species of copepods were collected including three new species of Hatschekia. Two species of isopods were collected, which include: a new species of Aega infected the gills of L.mahsena and one larval species of the genera Gnathia was collected on the gills of all host fishes. Two species of monogeneans of the genera Encotyllabe and Lamellodiscus, were collected on the gills from the five different species of lethrinid fishes. Five species of digenetic trematodes from two families and five genera were collected. One species of cestode larvae from the order (Tetraphyllidea) of three cercoide stages were isolated. Five species of nematodes of three families are suggested to be new species. Since there is no previous report on all these mentioned parasites from lethrinid fishes from the Red Sea, Saudi Arabia, the present recording may be considered the first at this geographical region of the country.
