The philometrid nematode, Philometra saltatrix Ramachandran, 1973, is redescribed from male and female specimens collected from the ovaries of the marine fish (bluefish) Pomatomus saltatrix (L.) (Pomatomidae, Perciformes) from the Tuscan Sea, Italy. The light and scanning electron microscopical examination made it possible to study in detail the morphology of this so far little known species. For the first time, the actual structure of the male cephalic and caudal ends is described. The male possesses 14 small cephalic papillae arranged in two circles, the spicules are 84-111 mu m long and the gubernaculum, 75-84 mu m long, has its distal portion provided with dorsal transverse lamella-like structures. The caudal end of subgravid females bears two very small, hardly visible lateral papilla-like projections. This is the first record of P. sallatrix, a species originally described from the West Atlantic, from the Tuscan Sea and the second one in the Mediterranean region.
