RESUMEN
Sagum posteli Delamare-Deboutteville & Nunes-Ruivo, 1954 (Copepoda: Lernanthropidae) is reported from the white grouper Epinephelus aeneus Geoffroy Saint-Hilaire caught off the Turkish Mediterranean coast. This documents the first discovery of this species in the Mediterranean and is only the second record. The species is redescribed from adult females and the cephalothoracic limbs are described for the first time. The valid species of the genus Sagum Wilson, 1913 are reviewed, and the poorly described species S. poeyi Ortiz, Lalana & Suarez, 2003 is relegated as a junior synonym of S. texanum Pearse, 1952, described from the same host. A key is provided to females of the ten valid species of Sagum and the known hosts for all species are summarised.

A detailed redescription of Lernanthropus kroyeri van Beneden, 1851 is provided based on observations made with the aid of scanning electron microscopy. Specimens were obtained from the host, the sea bass Dicentrarchus labrax (L., 1758) obtained from a commercial aquaculture enterprise in Izmir (western Turkey).

This study was carried out to investigate the reasons for scale loss, hemorrhage and local lesions on the skin of cultured meagre (Argyrosomus regius Asso, 1801), that are an alternative to the sea bass and sea bream. All of the 40 fish examined (5.63 +/- 0.89 kg in weight, 91.3 +/- 3.6 cm in length) had parasites on the area with lesions and the parasite was identified as Benedenia sciaenae van Beneden, 1856 (Monogenea: Capsalidae) after examination. The dimensions of the parasite were measured and drawn. This is the first report of B. sciaenae in Turkey.
