A new nematode species, Philometra spicarae sp. n. (Philometridae), is described from a gravid female found in the abdominal cavity of spicarel, Spicara smaris (Linnaeus) (Centracanthidae, Perciformes), from the Ionian Sea off Sicily, Italy. The new species differs from most other Philometra spp. parasitic in the abdominal cavity of marine fishes by the oesophagus without an anterior inflation, resembling thus only Philometra cheilopogoni Mordvinova, 1986 and Philometra justinei Moravec, Ternengo and Levron, 2006; these two species can be differentiated from P. spicarae by the relative length of the oesophagus to body length (0.6-0.8% vs. 6%) and some other features. From the gonad-infecting species Philometra filiformis (Stossich, 1896), a parasite of Pagellus erythrinus (Linnaeus), P. spicarae differs mainly in having a conspicuously long (1.4 mm) intestinal ligament. It is the first nominal philometrid species described from the fish of the family Centracanthidae.
