A new nematode species, Philometra diplectri n. sp. (Philometridae), is described from male and female specimens found in unidentified tissues of head and anterior trunk (males), and subcutaneously in the mouth and under the operculum (females) of sand perch, Diplectrum formosum (Linnaeus) (Serranidae, Perciformes). Based on light and scanning electron microscopy examination, the new species differs from other congeners parasitizing the subcutaneous tissues, fins, the tissues of the buccal cavity, gill covers or gill arches of marine and brackish-water fishes mainly in having 8 conspicuously large cephalic papillae of the external circle, the absence of caudal projections and the shape and small size of the anterior inflation of the esophagus in gravid female, and in possessing 5 pairs of caudal papillae and spicules 66-78 µm long in male. Philometra diplectri is the first known species of this genus whose gravid females are parasitic in the head tissues of serranid fishes.
