The male and subgravid female of Philometra serranellicabrillae Janiszewska, 1949 (Philometridae) collected from the gonads of Serranus cabrilla (Linnaeus) (Serranidae) off Tunisia are described for the first time based on light and scanning electron microscopical studies. The male of this nematode can be separated from other congeneric gonad-infecting nominal species in the structure and shape of the gubernaculum (e.g. absence of a dorsal protuberance and a median smooth field). The shape of the male posterior region is unique in that it bears a pair of big circular papillae posterior to the cloacal opening, which is also present in other Philometra spp. from serranids, i.e. P. indica Moravec & Manoharan, 2014, P. inexpectata Moravec, Chaabane, Justine & Neifar, 2016 and P. jordanoi (López-Neyra, 1951) Yamaguti, 1961. Moreover, P. serranellicabrillae differs from its congeners in other fish families from the Mediterranean Sea, in the length of spicules and gubernaculum.
基于光学显微镜和扫描电子显微镜研究，首次描述了1949年由贾尼谢夫斯卡发现的寄生于突尼斯近海的锯鳃鲈（鲈科）性腺中的细锯鳃鲈嗜子宫线虫（嗜子宫线虫科）的雄性和亚怀卵雌性。该线虫雄性在 gubernaculum 的结构和形状上（例如没有背突起和中间光滑区域）可与其他同类性腺感染的命名物种区分开来。雄性后部区域的形状独特，即泄殖孔开口后方有一对大的圆形乳突，这在其他来自鲈科鱼类的嗜子宫线虫属物种中也存在，即2014年的印度嗜子宫线虫、2016年的意外嗜子宫线虫、莫拉韦克、查巴内、朱斯汀和奈法尔，以及1961年由山口描述的约氏嗜子宫线虫。此外，细锯鳃鲈嗜子宫线虫在交合刺和 gubernaculum 的长度上与地中海其他鱼类科的同类物种不同。
