A new nematode species, Philometroides khalili n. sp. (Philometridae), is described from female specimens recovered from the operculum of the freshwater cyprinid fish Labeo rosae Steindachner (Cyprinidae, Cypriniformes) caught in the Bubi River, Zimbabwe. Based on light and scanning electron microscopical examination, the new species mainly differs from the only other African congeneric species P. africanus Moravec et Van As, 2001 in the body shape (filiform), length of gravid female (56 - 71 mm), in possessing a large oesophageal gland with a conspicuously large cell nucleus and in the shape (transversely oval), size (up to 33 - 36 μm high) and distribution of cuticular bosses. From other congeners it differs by a combination of morphological and biometrical features
