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.
对来自阿尔及利亚海岸的笛鲷属（硬骨鱼纲：鲷科）的双鳞盘虫鳃寄生虫的研究表明，在黑棘鲷（林奈）和真鲷（ Geoffroy Saint - Hilaire）上存在几种1922年约翰斯顿和蒂格斯描述的鳞盘虫属物种。其中一些物种与其他物种的不同之处在于具有“七弦琴状”的交配器官以及奥利弗（1987年）形态学组“ignoratus”的鳞盘。在鳞盘虫属中，阿明和厄泽特（2005年）提出的“ignoratus”亚组，其特征为具有简单的侧背杆，包括1943年的ignoratus鳞盘虫和1957年的fraternus鳞盘虫。两个新物种，falcus鳞盘虫新种和neifari鳞盘虫新种属于“ignoratus”亚组。这些物种通过钩器和交配器官的硬化部分的形态和大小来区分。
