    Abstract:
    Two species of Philometra Costa, 1845 (Nematoda: Philometridae), were, for the first time, recorded from fishes of the family Sparidae (porgies) from the Tyrrhenian Sea off Sicily, Italy: Philometra obladae sp. n. from the body cavity of the saddled seabream Oblada melanura (Linnaeus) and Philometra filiformis (Stossich, Boll Soc Adriat Sci Nat 17:121-136, 1896) from the gonads of the common pandora Pagellus erythrinus (Linnaeus). The new species (a single gravid female available) is characterised mainly by a large body (335 mm long, 3.4 mm wide), minute cephalic papillae (14 in number) arranged in two circles, a relatively short (1.29 mm) oesophagus with a distinct anterior inflation, a rounded caudal end without any projections and the length of larvae (549-600 mum) from the uterus. A key to species of Philometra with females located in the body cavity of marine and brackish-water fishes is given. Some new data on the female morphology of a little-known gonad-infecting species P. filiformis are provided; new observations revealed, for the first time in this species, the presence of lateral cephalic papillae and the absence of previously reported black intestinal corpuscles in the larvae.
