Abstract

The study of the diplectanid gill parasites of Diplodus Rafinesque (Teleostei: Sparidae) from off the Algerian coast revealed the presence of several species of Lamellodiscus Johnston & Tiegs, 1922 on D. sargus (Linnaeus) and D. vulgaris (Geoffroy Saint-Hilaire). Some of these species differ from the others by having a copulatory organ "en lyre" and lamellodiscs of the morphological group 'ignoratus' of Oliver (1987). In Lamellodiscus, the subgroup 'ignoratus', proposed by Amine & Euzet (2005), characterised by a simple lateral dorsal bar, includes L. ignoratus Palombi, 1943 and L. fraternus Bychowsky, 1957. Two new species, L. falcus n. sp. and L. neifari n. sp. form part of the 'ignoratus' subgroup. These species are distinguished by the morphology and the size of the sclerotised parts of the haptor and copulatory organ.
