The male of the gonad-infecting nematode Philometra filiformis (Stossich, 1896) (Philometridae) is for the first time described, based on specimens from the ovary of the marine fish Pagellus erythrinus (Linnaeus) from the Tyrrhenian Sea off Sicily, Italy. It is mainly characterized by the testis extending anteriorly nearly to the anterior end of body, the oesophagus without a usual anterior inflation, the absence of a dorsal barb or distinct transverse lamellae on the tip of the gubernaculum, the measurements of the spicules and the gubernaculum, and a fairly long body.
