Gravid or subgravid females of the following three species belonging to the nematode genus
Philometra were collected from marine perciform fishes of the Bonifacio Strait Marine Reserve, Corsica, France:
Philometra justinei sp. nov. (prevalence 1.5%, intensity 11) and
Philometra sp. (prevalence 3%, intensity 2) from the abdominal cavity and gonads, respectively, of the striped red mullet
Mullus surmuletus (Mullidae), and
Philometra serranellicabrillae Janiszewska, 1949 (prevalence 27%, intensity 2–6) from the gonads of the comber
Serranus cabrilla (Serranidae). The newly described species,
P. justinei, is mainly characterized by the absence of an anterior bulbous inflation of the oesophagus, body length of the gravid female
(196 mm), conspicuously large amphids, number and distribution of cephalic papillae, and the morphology of larvae. It is the
second known species of
Philometra parasitizing fishes of the family Mullidae and the ninth species of this genus reported from marine fishes of the Mediterranean
region.
P. serranellicabrillae, studied for the first time by SEM, is redescribed.
