Two nematode species of the genus Philometra Costa, 1845, P. ocularis Moravec, Ogawa, Suzuki, Miyazaki et Donai, 2002 (gravid and nongravid females) and P. lateolabracis (Yamaguti, 1935) (males and nongravid females), were recorded from the ocular cavity and ovaries, respectively, of serranid fishes (Serranidae, Perciformes) off New Caledonia, South Pacific. The gravid female of P. ocularis was found to attain a body length up to 96 mm (as compared to 59 mm in the original description). The males of P. lateolabracis are described from fishes of the Pacific region for the first time; their spicules were found to be 147-213 µm in length, suggesting thus the synonymy of the recently re-established species P.jordanoi (López-Neyra, 1951) with P. lateolabracis. The findings of P. ocularis in Epinephelus coioides, E. cyanopodus, E. rivulatus and Variola louti, and P. lateolabracis in Epinephelus cyanopodus and E. fasciatus represent new host records. Both nematode species are reported for the first time from the region of New Caledonia, and P. ocularis from the South Pacific Ocean.

Deux espèces de Nématodes du genre Philometra Costa, 1845, P. ocularis Moravec, Ogawa, Suzuki, Miyazaki et Donai, 2002 (femelles gravides et non gravides) et P. lateolabracis (Yamaguti, 1935) (mâles et femelles non gravides), ont été recensées des cavités oculaires et des ovaires, respectivement, de mérous (Perciformes, Serranidae) de Nouvelle-Calédonie, Pacifique Sud. La femelle gravide de P. ocularis atteint une longueur de 96 mm (à comparer aux 59 mm de la description originale). Les mâles de P. lateolabracis sont décrits de poissons du Pacifique pour la première fois; leurs spicules sont longs de 147-213 µm, ce qui suggère la synonymie de l'espèce récemment ré-établie P. jordanoi (López-Neyra, 1951) avec P. lateolabracis. P. ocularis chez Epinephelus coioides, E. cyanopodus, E. rivulatus et Variola louti, et P. lateolabracis chez Epinephelus cyanopodus et E.fasciatus fournissent des mentions de nouveaux hôtes. Les deux espèces de Nematodes sont mentionnées pour la première fois de Nouvelle-Calédonie, et P. ocularis pour la première fois dans l'Océan Pacifique Sud.
