As most fish, Lethrinus nebulosus is the host of many species of parasites.Monogeneans parasitic on the gills include the diplectanids Calydiscoides difficilis, Calydiscoides duplicostatus and Calydiscoides terpsichore, an ancyrocephalid, and an unidentified polyopisthocotylean. The pharyngeal teeth harbour a species of the capsalid monogenean Encotyllabe which is specialised to this special habitat. Copepods parasitic on the gills include three species of the hatschekiid Hatschekia including Hatschekia gracilis. The digestive tract harbours the opecoelid Macvicaria macassarensis and the zoogonid Diphterostomum tropicum. In New Caledonia, where its parasites were studied, Lethrinus nebulosus has a total of eleven species of parasites.
