Examinations of marine fishes off New Caledonia, South Pacific, carried out in 2003–2006, yielded some nematodes of the genus Philometra Costa, 1845, including the following three new species: P. cyanopodi sp. nov. (males and subgravid females) and P. lethrini sp. nov. (males and subgravid females) from the gonads of Epinephelus cyanopodus (Richardson) (Serranidae) and Lethrinus genivittatus Valenciennes (Lethrinidae), respectively, and P. lagocephali sp. nov. (gravid female) from the abdominal cavity of Lagocephalus sceleratus (Gmelin) (Tetraodontidae). Another congeneric species P. fasciati sp. nov. from the gonads of Epinephelus fasciatus (Forsskål) (Serranidae), originally reported as P. lateolabracis (Yamaguti, 1935), has been established with reference to the description of males and a mature female published by Moravec and Justine (2005). The new species are characterized mainly by the length of spicules and the length and structure of the gubernaculum, structure of the male caudal end (except for P. lagocephali), body size, location in the host and by the types of hosts. In addition, Philometra sp. (subgravid females) from the gonads of Lutjanus vitta (Quoy et Gaimard) (Lutjanidae) and Philometra cf. ocularis Moravec et al., 2002 (gravid female) from the oculo-orbit of Epinephelus areolatus (Forsskål) were found, the latter representing a new host record.

L’examen de poissons marins de Nouvelle-Calédonie, Pacifique Sud, pratiqué en 2003–2006, a permis de récolter des nématodes du genre Philometra Costa, 1845, y compris les espèces nouvelles suivantes: P. cyanopodi sp. nov. (mâles et femelles subgravides) et P. lethrini sp. nov. (mâles et femelles subgravides) respectivement des gonades de Epinephelus cyanopodus (Richardson) (Serranidae) et Lethrinus genivittatus Valenciennes (Lethrinidae), et P. lagocephali sp. nov. (femelle gravide) de la cavité abdominale de Lagocephalus sceleratus (Gmelin) (Tetraodontidae). Une autre espèce congénérique P. fasciati sp. nov., des gonades de Epinephelus fasciatus (Forsskål) (Serranidae), originellement rapportée comme P. lateolabracis (Yamaguti, 1935), a été établie par référence à la description des mâles et d’une femelle mûre publiée par Moravec et Justine (2005). Les nouvelles espèces sont caractérisées principalement par la longueurs du spicule, la structure du gubernaculum, la structure de l’extrémité caudale du mâle (sauf pour P. lagocephali), la taille du corps, la position chez l’hôte et le type d’hôte. De plus, Philometra sp. (femelles subgravides) des gonades de Lutjanus vitta (Quoy et Gaimard) (Lutjanidae) et Philometra cf. ocularis Moravec et al., 2002 (femelle gravide) de l’œil et de l’orbite de Epinephelus areolatus (Forsskål) ont été trouvés, le dernier représentant un nouvel hôte.
